Description

[0001] The present invention relates to an injection device.

[0002] A device has been proposed in which an insertion section (a lubrication line or the like) is inserted into a guide through-hole of a guide holding device attached to a coupling housing designed to be inserted into a corresponding section (a section to which grease must be supplied from a tip end section of the lubrication line) in a tight or narrow space (see, for example, the unexamined patent disclosure JP 2020-37949 A).

[0003] However, in JP 2020-37949 A, if foreign matter (sludge, dust, powder or the like) adheres to the relevant section in the confined space, the foreign matter cannot be removed, so that a problem arises in that grease is added which is mixed with the foreign matter.

[0004] The object of the present invention is to provide an injection device suitable for removing foreign substances adhering to a corresponding section in a confined space.

[0005] This problem is solved by the features of claims 1 and 4. Advantageous further developments are defined in the dependent claims.

[0006] An injection device according to a first aspect of the invention comprises an insertion section designed to be inserted into a corresponding section in a confined space while being grasped by an operator. The insertion section comprises an injection section, which is a double-walled pipe comprising an inner pipe and an outer pipe, the latter defining an annular pipe between the inner and outer pipes. The inner pipe includes, at a tip end section, a first fluid substance injection port designed to inject a grease as a first fluid substance supplied to the inner pipe.The annular pipeline is a pipeline comprising at a tip end section a second fluid substance injection port designed to inject air as a second fluid substance through a through-hole (203a) in the outer pipeline (203) connected to an air source (207). This air is supplied to the annular pipeline to remove foreign substances adhering to the corresponding section (C) in the confined space.

[0007] With such a configuration, foreign substances adhering to the corresponding section in the confined space can be removed by spraying the second fluid substance injected from the second fluid substance injection port towards the corresponding section.

[0008] In this respect, a pointed end of the inner pipe can protrude further than a pointed end of the outer pipe.

[0009] In this aspect, the introductory section may further comprise an imaging unit designed to capture an image containing the tip end section of the inner pipeline, the tip end section of the annular pipeline and a surrounding area of ​​the tip end section of the inner pipeline (202) and the tip end section of the annular pipeline.

[0010] An injection device according to a second aspect of the invention comprises an insertion section designed to be inserted into a corresponding section in a confined space while being grasped by an operator. The insertion section comprises an injection section comprising a first pipeline and a second pipeline arranged parallel to each other. The first pipeline includes, at a tip end section, a first fluid substance injection port designed to inject a grease as a first fluid substance supplied to the first pipeline.The second pipeline is a pipeline which includes at a tip end section a second fluid substance injection port designed to inject a second fluid substance from an air source supplied to the second pipeline to remove foreign matter adhering to the corresponding section (C) in the confined space.

[0011] In the first aspect and the second aspect, the first fluid substance can be a fluid substance that is supplied to the corresponding section, and the second fluid substance can be a fluid substance for removing foreign substances, which removes the foreign substances adhering to the corresponding section.

[0012] In the first aspect and the second aspect, the fluid substance can be an application fluid applied to the relevant section (C), and the fluid substance for removing foreign matter can be air.

[0013] With each aspect of the present invention, it is possible to provide an injection device suitable for removing foreign substances adhering to a corresponding section in a confined space.

[0016] A lubrication device for a clutch release mechanism is described below, specifically as a first embodiment (reference example) of the present invention, with reference to the drawings. The present invention is not limited to the embodiments described below. First embodiment

[0017] A lubrication device of a first embodiment is used to provide inexpensive and quick inspection and grease injection maintenance for sliding defects (for example, sliding disturbances with increased friction, abnormal noises) caused by leakage of lubricating grease (hereinafter referred to as "grease") from a fork grease lubrication section in an MT clutch housing and by contamination by foreign substances after a vehicle with a manual transmission has been flooded or crossed a river.

[0018] Fig. Figure 1 is a view schematically showing a clutch release mechanism of the first embodiment. As shown in Fig. As shown in Figure 1, a clutch device 1 comprises a clutch main body 10, which performs an engine connection / disconnection operation, a clutch release mechanism 20 for actuating the clutch main body 10, and a clutch housing 30 in which the clutch main body 10 is received. The clutch device 1 is, for example, installed in a vehicle with a manual transmission and is arranged between an engine and a transmission.

[0019] One in Fig. The X-direction shown represents an axial direction along a central axis, and a Z-direction represents a direction (which can be described as a radial direction or a vertical direction) orthogonal to the central axis. If the Z-direction is the vertical direction, a top side can be described as a tip end side and a bottom side as a base end side. Furthermore, a Y-direction, described below, represents a direction orthogonal to both the X-direction and the Z-direction. The Y-direction can be described as a horizontal direction.

[0020] The clutch body 10 comprises a clutch disc 11, a clutch cover 12, a pressure plate 13, a diaphragm spring 14 and a release bearing 15.

[0021] The clutch disc 11 has a friction surface (a clutch lining) that is arranged between the pressure plate 13 and a flywheel 16 and is splined to an input shaft 3 of the transmission. The rotation of the flywheel 16 is transmitted to the input shaft 3 by the frictional force between the friction surface of the clutch disc 11 and the flywheel 16. The flywheel 16 is bolted to a crankshaft 2 of the engine, and the flywheel 16 and the crankshaft 2 rotate together.

[0022] The clutch cover 12 covers an outer circumferential side of the clutch disc 11 and rotates together with the pressure plate 13 and the diaphragm spring 14. The pressure plate 13 is located between the friction surface of the clutch disc 11 and the diaphragm spring 14. The diaphragm spring 14 is used to press the friction surface of the clutch disc 11 against the flywheel 16 via the pressure plate 13 and is located on the side of the friction surface of the clutch disc 11 opposite the pressure plate 13. A circumferential edge section of the diaphragm spring 14 is connected to the pressure plate 13, and a central section of the diaphragm spring 14 is connected to the release bearing 15. This allows the diaphragm spring 14 to press against the pressure plate 13.

[0023] When the clutch main body 10 is engaged, the pressure plate 13 pushes the friction surface of the clutch disc 11 towards the side of the flywheel 16 by the elastic force of the diaphragm spring 14. This puts it into a coupled state in which a frictional force is generated between the friction surface of the clutch disc 11 and the flywheel 16, and the rotation of the flywheel 16 is transmitted to the clutch disc 11.

[0024] When the clutch main body 10 disengages, the release bearing 15 compresses the central section of the diaphragm spring 14, causing the circumferential edge section of the diaphragm spring 14 to be displaced away from the flywheel 16. In this case, the pressure plate 13, together with the diaphragm spring 14, is pulled away from the flywheel 16. This puts it into a disengaged state, in which the frictional force between the friction surface of the clutch disc 11 and the flywheel 16 is eliminated, and the rotation of the flywheel 16 is not transmitted to the clutch disc 11.

[0025] The clutch release mechanism 20 comprises a release fork 21, a release fork holder 22 and a release cylinder 23.

[0026] The release fork 21 is an element for moving the release bearing 15 in an axial direction and is pivotable while being held or supported by the release fork holder 22. The release fork 21 is an elongated metal element with a forked tip.

[0027] As it is in Fig. As shown in Figure 1, a first end face of the release fork 21 consists of a pressure section 21a, which presses the release bearing 15 in the axial direction. The pressure section 21a has a forked structure, in which the tip end face is forked to clamp the input shaft 3 in the clutch housing 30. A section (contact section) of the pressure section 21a, which faces the release bearing 15 in the axial direction, comes into contact with the release bearing 15. A second end face of the release fork 21 consists of a connecting section 21b, which projects from the clutch housing 30 through a through-hole 31 and is connected to the release cylinder 23. Furthermore, the second end face of the release fork 21 is covered at one position by a fork shoe 32, which extends from the clutch housing 30. The fork shoe 32 is attached to the through hole 31.The fork shoe 32 may be provided with a hole (cooling hole) to dissipate the frictional heat generated when the clutch main body 10 is in a half-engaged state from the clutch housing 30.

[0028] Furthermore, the release fork 21 comprises a pivot section 21c, which is supported between the pressure section 21a and the connecting section 21b by the release fork holder 22. The release fork holder 22 comprises a main body section attached to a wall section of the clutch housing 30 and a pivot section (not shown) with a spherical surface on a tip end face of the main body section. The wall section of the clutch housing 30 includes a retainer to which a bearing (not shown) for supporting the input shaft 3 is attached. The retainer is an element that is attached to the clutch housing 30. A base face of the release fork holder 22 is bolted to the retainer. Furthermore, a hub section 30a of the retainer extends along the input shaft 3 within the clutch housing 30. The input shaft 3 is inserted into the hub section 30a.

[0029] The release bearing 15 is axially movable relative to the hub section 30a by virtue of being supported on an outer circumference of the hub section 30a by a sleeve or bushing. The release bearing 15 is in contact with the central section of the diaphragm spring 14. The release bearing 15 has an outer ring, which is supported on the hub section 30a by a sleeve or bushing, and an inner ring, which is in contact with the central section of the diaphragm spring 14. In the release bearing 15, an inner ring, which is in contact with the diaphragm spring 14, rotates, while an outer ring, which is in contact with the release fork 21, does not rotate.

[0030] When a driver depresses a clutch pedal (not shown), the release cylinder 23 is activated. When the connecting section 21b is actuated by the release cylinder 23, the release fork 21 pivots with the pivot section 21c as its pivot point. Due to this pivoting, the pressure section 21a presses on the release bearing 15, and the release bearing 15 moves axially, whereupon the central section of the diaphragm spring 14 is pressed towards the side of the flywheel 16. As a result, the clutch main body 10 is switched to an open state. When the clutch main body 10 is in the open state, the flywheel 16 and the clutch disc 11 are separated, or decoupled, so that no power can be transmitted. When the actuating force from the release cylinder 23 is released, the pressure force acting on the release bearing 15 by the pressure section 21a disappears.As a result, the clutch main body 10 is switched into an engaged or coupled state. When the clutch main body 10 is switched into the engaged state, the flywheel 16 and the clutch disc 11 are connected so that they can transmit power. In this way, pivoting the release fork 21 connects and disconnects a power transmission path between the crankshaft 2 on the engine side and the input shaft 3 on the transmission side.

[0031] A lubrication device 100 of the first embodiment is described below. The lubrication device 100 is a device that supplies grease to the contact section between the pressure section 21a of the release fork 21 and the release bearing 15. The lubrication device 100 is designed such that a second holding device 120 (an insertion section 121) is inserted into guide through-holes (first hole 113, second hole 114) of a first holding device 110, which is attached to the clutch housing 30 as described below, and the second holding device 120 (the insertion section 121) is inserted into a corresponding section C up to a tip end section 131 of a lubrication line 130, which is arranged on the second holding device 120, and the corresponding section C has a predetermined spatial relationship. As described in Fig. As shown in Figure 1, the corresponding section C refers to a contact section between the release fork 21 (the pressure section 21a) and the release bearing 15, which is a lubrication-required section (a section to which grease must be supplied from the tip end section 131 of the lubrication line 130). As shown in Fig. As shown in Figure 1, the corresponding section C is arranged in an interior space enclosed by the coupling housing 30 (an example of a cover element of the present invention). The coupling housing 30 includes a through-hole (the through-hole 31) for attaching a retaining device, which is connected to the interior space.

[0032] When a vehicle equipped with the clutch device 1 is used in an environment containing sand, muddy water, and the like, foreign matter can enter the clutch housing 30 through the cooling hole of the fork shoe 32 described above, the cooling hole provided in the clutch housing 30, or an opening section (none of which are shown) for draining water. Therefore, it is desirable to service the clutch release mechanism 20 and perform lubrication maintenance to supply additional grease to the contact section between the release fork 21 and the release bearing 15. The lubrication device 100 is therefore designed so that lubrication maintenance can be performed without having to attach or remove the clutch housing 30 (or a transmission unit that includes the clutch housing 30) from the vehicle.This lubrication device 100 supplies grease from outside the clutch housing 30 through the through-hole 31 of the clutch housing 30 to the contact section between the release fork 21 and the release bearing 15, which is the section requiring lubrication, using the lubrication line 130 (in . Fig. 2 and the like shown).

[0033] As it is in Fig. As shown in Figure 2, the lubrication device 100 comprises the first holding device 110, the second holding device 120, the lubrication line 130, a flexible line 140, and a lubrication device 150. The first holding device 110 and the second holding device 120 are elements for positioning the lubrication line 130. The first holding device 110 is an element that is attached to the through-hole 31 of the coupling housing 30. The second holding device 120 is an element that is inserted into the insertion hole of the first holding device 110.

[0034] The first retaining device 110 is a guide retaining device that regulates the direction (insertion direction) of the lubrication line 130 (grease injection line) and comprises a base section 111, a projection 112, and the first hole 113 and the second hole 114 as positioning holes. This first retaining device 110 is a one-piece formed metal product. The base section 111 is formed in the form of a flat plate and has a shape suitable for partially covering the opening portion of the through-hole 31. The width (the length in the Y-direction described below) of the base section 111 is greater than the opening width of the through-hole 31. The projection 112 is a section that projects from the base section 111 and is a section that is inserted into the through-hole 31.The projection 112 serves as a positioning section for positioning the first holding device 110 by resting against an inner surface 31a of the through hole 31 and against a plane 21d of the release fork 21.

[0035] The first hole 113 and the second hole 114 are insertion holes into which the lubrication line 130 and the insertion section 121 of the second retaining device 120 are inserted, and are positioning holes for positioning the lubrication line 130. The first hole 113 and the second hole 114 are formed side by side in the width direction of the first retaining device 110, and both are through holes extending from the base section 111 on a base end face toward the projecting section 112 on a tip end face. In this description, the term "insertion hole" is used when the first hole 113 and the second hole 114 are not specifically distinguished.

[0036] In the second holding device 120, the insertion section 121 has a square, cylindrical shape that is inserted into the first hole 113 and the second hole 114 of the first holding device 110, and a stop section 122 that rests against a surface 111a of the first holding device 110. This second holding device 120 is a one-piece molded metal product. Furthermore, the lubrication line 130 is integrated with the second holding device 120. The second holding device 120 has two through-holes 123, 124 that extend linearly along the insertion section 121 from the base end to the tip end. One through-hole 123 is for a lubrication line. The other through-hole 124 is for an endoscope. A lubrication line 130 is secured in the through-hole 123 when inserted. An endoscope 160 is secured in the inserted state in the through-hole 124 (see Fig. 3) Furthermore, the stopper section 122 has a stopper surface 122a (shown in Fig. 3), which rests on the surface 111a of the first holding device 110.

[0037] The lubrication line 130 is a line for supplying grease to the contact section between the pressure section 21a of the release fork 21 and the release bearing 15 in the clutch housing 30. The lubrication line 130 is a long injection section comprising the tip end section 131 through which grease (an example of the fluid substance of the present invention) is injected. This lubrication line 130 is made of metal. The tip end section 131 of the lubrication line 130 comprises an opening section 131a (hereinafter also referred to as an injection port 131a) for injecting grease. The flexible line 140 is connected to the base end of the lubrication line 130. The lubrication line 130 is connected to the lubrication device 150 via the flexible line 140.

[0038] As it is in Fig. As shown in Figure 3, the lubrication device 100 comprises an endoscope 160 as an imaging means. The endoscope 160 is a long imaging device with an imaging unit for capturing an image that includes the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C) in a tip end section 160a. The endoscope 160 is an example of an imaging device of the present invention. The endoscope 160 is integrated into the second holding device 120 and projects from the tip end of the insertion section 121. The tip end of the endoscope 160 is a section that is inserted into the coupling housing 30, and a lens is arranged on a tip end section 161a. The base end of the endoscope 160 is connected to an actuating section 162 via a cable 161. By actuating the actuating section 162, the internal structure of the coupling housing 30 can be photographed through the endoscope 160.An image (for example, an image showing the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C)), taken with the endoscope 160, can be displayed on a display section 163 attached to the actuating section 162.

[0039] The lubrication device 150 comprises a cylinder 151 and a push rod 152 (piston) (see Fig. 3) A flexible line 140 is connected to the cylinder 151 of the lubrication device 150. By pressing the push rod 152 with the cylinder 151 filled with grease, the grease can be supplied from the lubrication device 150 to the lubrication line 130. It is also possible to carry out the lubrication smoothly by, for example, inserting the lubrication line 130 into the clutch housing 30 via the through-hole 31, pre-filling grease into the lubrication line 130 and the flexible line 140, and then actuating the lubrication device 150.

[0040] The tip end section 131 of the lubrication line 130 has a reduced diameter shape and includes the opening section 131a for injecting grease. For example, the opening section 131a of the lubrication line 130 can have a circular shape, as shown in Fig. 4A is shown. Alternatively, as shown in Fig. As shown in Figure 4B, the opening section 131a can have a flat shape. Since the tip end section 131 of the lubrication line 130 has a reduced diameter, it is possible to lubricate the section requiring lubrication through a narrow space in the coupling housing 30.

[0041] The first holding device 110 is described in detail below with regard to the Fig. 5 and 6A to 6C described. Fig. Figure 5 is a top view of the base end face of the first holding device 110. Fig. 6A is a view from the direction of arrow A in Fig. 5. Fig. Figure 6B is a perspective view from the rear of the first holding device 110. Fig. 6C is a view showing a cross-section along the VIC-VIC line of Fig. 5 shows.

[0042] As it is in Fig. As shown in Figure 5, the first holding device 110 comprises rectangular opening sections of the first hole 113 and the second hole 114 on the side of surface 111a of the base section 111. The inner surface of the first hole 113 is a surface that serves as a guide surface for positioning the lubrication line 130 by causing the insertion section 121 to bear against it. The inner surface of the first hole 113 has a first surface 113a, a second surface 113b, a third surface 113c, and a fourth surface 113d. The first surface 113a and the second surface 113b are surfaces facing each other in the Y direction and each form a short side of the rectangular shape. The third surface 113c and the fourth surface 113d are surfaces facing each other in the X direction and each form a long side of the rectangular shape.The inner surface of the second hole 114 is a surface that serves as a guide surface for positioning the lubrication line 130 and has a first surface 114a, a second surface 114b, a third surface 114c, and a fourth surface 114d. The first surface 114a and the second surface 114b are surfaces facing each other in the Y-direction and each form a short side of the rectangular shape. The third surface 114c and the fourth surface 114d are surfaces facing each other in the X-direction and each form a long side of the rectangular shape.

[0043] Furthermore, the first holding device 110 has a contact surface 115 that rests against the plane 21d of the release fork 21. The contact surface 115 is a positioning surface, and the position of the first holding device 110 in the X-direction can be determined by ensuring that the contact surface 115 rests against the plane 21d of the release fork 21. As shown in Fig. As shown in Figure 6A, the mounting surface 115 has a predetermined width in the lateral direction (Y-direction) of the base section 111 and extends in the vertical direction (Z-direction) of the projection section 112.

[0044] As it is in Fig. As shown in Figure 6B, a key section 116 is arranged on one side of a rear surface 111b of the first retaining device 110. The key section 116 is a section that engages with the coupling housing 30 when the projection 112 is inserted into the through-hole 31. This key section 116 serves as a section for holding the first retaining device 110 in the through-hole 31. Furthermore, opening sections of the first hole 113 and the second hole 114, which are open into the projection 112, are also rectangular, as on the base end side. As shown in Fig. As shown in 6C, the first hole 113 extends linearly into the projection 112.

[0045] The following is a lubrication procedure using the lubrication device 100 with regard to the Fig. Described in sections 7 to 9. Fig. Figure 7 is a view showing a state in which the first retaining device 110 is attached to the through-hole 31 of the coupling housing 30. Fig. Figure 8 is a view showing a condition in which the lubrication line 130 extends towards the pressure section 21a of the release fork 21, with the second retaining device 120 inserted into the insertion hole of the first retaining device 110. Fig. Figure 9 is a view used to illustrate the vertical position of the tip end section 131 of the lubrication line 130. The in Fig. Figure 9 shows the Z-direction as representing the height direction. The fork shoe 32 is removed before the following steps are carried out. As a result, the through hole 31 (see the Fig. 2, Fig. 9 and the like) of the clutch housing 30 for the insertion of the lubrication line 130 and the like, exposed.

[0046] As a first step, the first holding device 110 is attached to the through-hole 31 of the coupling housing 30 (an example of a fixing target element of the present invention).

[0047] Fig. Figure 11 is a view showing the first holding device 110 and the second holding device 120. Fig. 9 shows.

[0048] As it is in Fig. As shown in Figure 11, the first holding device 110 is attached to the coupling housing 30 (circumferential section of the through hole 31) in a state in which it is positioned in the X direction, the Y direction and the Z direction with respect to the coupling housing 30.

[0049] In particular, the projection 112 of the first holding device 110 and the through hole 31 of the coupling housing 30 are first facing each other (see Fig. 2), and the mounting surface 115 of the first holding device 110 and the release fork 21 (level 21d) are facing each other (contact) (see Fig. 7).

[0050] Then the projection 112 of the first holding device 110 is inserted into the through hole 31, and the first holding device 110 is pushed along the release fork 21 (plane 21d) in one direction (see the arrow AR1 in Fig. 2), in which it is brought close to the through hole 31 until the base section 111 of the first holding device 110 rests against the circumferential section of the through hole 31 of the coupling housing 30.

[0051] By inserting the projecting section 112 of the first holding device 110 into the through hole 31 and causing the side surfaces 112a and 112b of the projecting section 112 and the inner surfaces 31a and 31b of the through hole 31 to face each other (abutting each other), the first holding device 110 is positioned in the Y direction with respect to the coupling housing 30.

[0052] Furthermore, the first holding device is positioned in the Z direction with respect to the coupling housing 30 by causing the base section 111 of the first holding device 110 to abut the circumferential section of the through hole 31 of the coupling housing 30.

[0053] The first holding device 110 is then positioned in the Y-direction and the Z-direction with respect to the coupling housing 30 in the direction of arrow AR2 (see the Fig. 7 and Fig. 11) pressed.

[0054] In particular, the circumferential section of the through-hole 31 of the coupling housing 30 is placed in a space between the base section 111 and the key section 116 of the first retaining device 110 (see Fig. 11) inserted (pressed in), and the first retaining device 110 is positioned in the Y-direction and the Z-direction with respect to the clutch housing 30 in the direction of arrow AR2 (see the Fig. 7 and Fig. 11) pressed until the circumferential section of the through-hole 31 meets a bottom section 117 between the base section 111 and the key section 116 of the first retaining device 110.

[0055] A distance A1 (see Fig. 11) between the base section 111 and the key section 116 of the first holding device 110 and a thickness B1 (see Fig. 11) The circumferential section of the through-hole 31 of the coupling housing 30 is adjusted such that the relationship A1 < B1 is satisfied. Therefore, when the first holding device 110 is in a state positioned in the Y-direction and the Z-direction with respect to the coupling housing 30, as described above, in the direction of arrow AR2 (see the Fig. 7 and Fig. 11) is pressed, the circumferential section of the through-hole 31 of the coupling housing 30 is inserted (pressed in) into the space between the base section 111 and the key section 116 of the first retaining device 110. As a result, the first retaining device 110 is fastened to the coupling housing 30.

[0056] By causing the circumferential section of the through-hole 31 of the clutch housing 30 to meet the bottom section 117 between the base section 111 and the key section 116 of the first retaining device 110, the first retaining device 110 is positioned in the X direction with respect to the clutch housing 30.

[0057] As described above, the first retaining device 110 is attached to the clutch housing 30 in a position relative to the clutch housing 30 (the circumferential section of the through-hole 31) in the X, Y, and Z directions (the example of the fixing target element of the present invention). In other words, the first retaining device 110 engages in the circumferential section of the through-hole 31 of the clutch housing 30 in a position relative to the clutch housing 30 in the X, Y, and Z directions. The base section 111 and the key section 116 of the first retaining device 110 are examples of engagement sections of the present invention.

[0058] In a state in which the first retaining device 110 has been attached to the coupling housing 30 (the circumferential section of the through-hole 31) in this manner, the first hole 113 of the first retaining device 110 extends in the direction of the corresponding section C (the first pressure section 21a) (see Fig. 9) Accordingly, the second hole 114 of the first retaining device 110 extends towards the corresponding section C (of the second pressure section 21a). The first retaining device 110 can be removed from the coupling housing 30 by reversing the procedure.

[0059] As the next step of the first step, an insertion step is performed in which the lubrication line 130 and the second retaining device 120 are inserted into the insertion hole (the first hole 113, the second hole 114) of the first retaining device 110, which has been attached to the coupling housing 30 as described above. Once the second retaining device 120 is inserted into the insertion hole (the first hole 113, the second hole 114) of the first retaining device 110 in this insertion step, a two-step insertion step is performed for the second retaining device 120. In a second embodiment, marking lines, described below, are applied to side surfaces 121a and 121b of the insertion section 121 of the second retaining device 120 at positions at a predetermined distance from the tip end face. The outer circumferential shape of the insertion section 121 is rectangular.The side surfaces 121a and 121b are short side segments of a rectangular shape. Furthermore, side surface 121a is the first surface in the Y-direction, and side surface 121b is the second surface in the Y-direction. Additionally, the rectangular shape of the insertion segment 121 is smaller than the rectangular shape of the opening segment of the first hole 113 and the rectangular shape of the opening segment of the second hole 114.

[0060] As it is in Fig. As shown in Figure 8, the lubrication line 130 extends through the insertion of the insertion section 121 of the second retaining device 120 into the first hole 113 of the first retaining device 110 towards the pressure section a of the release fork 21, which is the section requiring lubrication. Since the pressure section 21a has a forked structure, the lubrication line 130 inserted into the first hole 113 extends towards the first pressure section 21a. At the point when the lubrication line 130 reaches the vicinity of the pressure section 21a of the release fork 21, it may be necessary to bypass or avoid obstructions in the clutch housing 30. For example, an obstruction could be a clip that is a component of the release bearing 15. Since the clamp is located near the forked structure of the release fork 21, it is desirable that the lubrication line 130 does not hit the clamp before it reaches the pressure section 21a.

[0061] As a second step (the first half-step of the insertion step), the insertion section 121 of the second retaining device 120 is inserted into the insertion hole of the first retaining device 110 up to the position of the marking line. With this second step in place, the lubrication line 130 and the endoscope 160 can be actuated to reposition the second retaining device 120 relative to the first retaining device 110 within the insertion hole, so that the lubrication line 130 and the endoscope 160 can avoid or bypass obstructions in the clutch housing 30. That is, as a third step (avoidance step), the second retaining device 120 is actuated to bypass the internal structure of the clutch housing 30.In the following steps, an operator, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C)) displayed on the display section 163, which is attached to the actuating section 162, which he has grasped with one hand (for example, the right hand), guides the second holding device 120 (insertion section 121), grasped with the other hand (for example, the left hand), into the corresponding section C in one direction (see the . Fig. 9 and Fig. 11) of arrow AR3, so that the tip end section 131 of the lubrication line 130 reaches the corresponding section C (see Fig. 9).

[0062] In the third step, when the insertion section 121 is inserted into the first hole 113, a clearance (approximately 0.5 mm) is provided between the side surfaces 121a and 121b of the insertion section 121 and the inner surface (inner wall) of the first hole 113. Similarly, when the insertion section 121 is inserted into the second hole 114, a clearance (approximately 0.5 mm) is provided between the side surfaces 121a and 121b of the insertion section 121 and the inner surface (inner wall) of the second hole 114. Therefore, if the second holding device 120 is inserted into the insertion hole up to the position of the marking line, the lubrication line 130 can be positioned at a height where the lubrication line 130 does not come into contact with the clamp of the release bearing 15, and in a position where it avoids the internal structure such as the clamp.In this case, it is possible to hold the side of the stopper section 122 in the hand and to pivot the tip end side of the insertion section 121 in the Y direction.

[0063] As it is in Fig. As shown in Figure 9, the tip section 131 of the lubrication line 130 is located at such a height that the tip section 131 of the release bearing 15 is not clamped at a height h1. In this case, the insertion of the lubrication line 130 is stopped and the position of the tip section 131 is controlled to prevent clamping of the release bearing 15. This height h1 further represents the insertion amount (stroke amount).

[0064] For example, in the third step, starting from the state in which the side surface 121b of the insertion section 121 rests against the first surface 113a of the first hole 113, the lubrication line 130 is actuated to prevent obstructions inside the coupling housing 30. This brings the side surface 121a of the insertion section 121 into contact with the second surface 113b of the first hole 113, which had been in a non-contact state. In this case, the second holding device 120 is moved until the insertion section 121 slides on the third surface 113c of the first hole 113 and the side surface 112a comes into contact with the second surface 113b. This sliding involves a parallel translational movement in the Y direction and a pivoting of the side of the tip end section 131 from right to left.As a result, the lubrication line 130 is in a position where it does not come into contact with the clamp.

[0065] In this way, once the position of the lubrication line 130 is fixed at a position where it can avoid the obstruction in the clutch housing 30, the tip end section 131 of the lubrication line 130 is brought back into contact with the section requiring lubrication. That is, the insertion step of the second retaining device 120 is restarted, and the insertion section 121 is inserted into the through-hole 31 until the stop section 122 of the second retaining device 120 rests against the base section 111 of the first retaining device 110. In a state where the stop section 122 of the second retaining device 120 is in contact with the first retaining device 110, the tip end section 131 of the lubrication line 130 is inserted into the clutch housing 30 to a predetermined target position.That is, as a fourth step (the second half of the insertion step), the insertion section 121 is inserted deeper than the position of the marking line, and the tip end section 131 of the lubrication line 130 is inserted into the section requiring lubrication.

[0066] As it is in Fig. As shown in Figure 9, the tip end section 131 of the lubrication line 130 reaches a height h2 in the fourth step, where one of the forked structures, the first pressure section 21a, is located. Thus, it can be determined that the tip end section 131 of the lubrication line 130 is located in the vicinity of the pressure section a of the release fork 21. This height h2 has a greater inlet value than the height h1.

[0067] Then, as a fifth step, a step is carried out to supply grease from the opening section 131a of the lubrication line 130. In the fifth step, the operator, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C)) displayed on the display section 163 attached to the actuating section 162, which he has grasped with one hand (for example, the right hand), grasps the lubrication device 150 with the other hand (for example, the left hand) and actuates it (for example, presses the button in the display section 163). Fig. 3 push rod 152 shown in its axial direction), to supply grease from the opening section 131a of the lubrication line 130 to the corresponding section C (see Fig. 9) In the fifth step, once a suitable quantity of grease has been supplied by the lubricating device 150, which is connected to the lubrication line 130, a suitable quantity of grease is ejected from the tip section 131 of the lubrication line 130, and the grease is applied to the pressure section 21a. In this case, the grease is pre-filled into the lubrication line 130 by the lubricating device 150. Therefore, once the tip section 131 of the lubrication line 130 is determined to be in the desired position, lubrication is carried out smoothly by actuating the lubricating device 150.

[0068] Then, once the lubrication process is complete in the fifth step, the lubrication line 130 is removed in a sixth step. In this sixth step, the grease is cut off from the tip section 131 of the lubrication line 130 while the first retaining device 110 is attached to the through-hole 31. The second retaining device 120 is then removed from the through-hole 31, and the tip section 131 of the lubrication line 130 is also removed from the through-hole 31 to the outside of the clutch housing 30.

[0069] For example, the second retaining device 120 is removed from the insertion hole of the first retaining device 110. Once the second retaining device 120 is removed from the insertion hole of the first retaining device 110, it can be pivoted from right to left around the gap between the insertion hole and the insertion section 121. As a result, it is possible to prevent grease from adhering to sections and parts other than the section requiring lubrication.

[0070] If the steps described above, from the first to the fifth step, are steps for the first hole 113, then the steps from the second to the fifth step are performed for the second hole 114. This makes it possible to lubricate both pressure sections 21a with the forked structure while maintaining the fixed state of the first holding device 110.

[0071] If there are no obstructions in the clutch housing 30 up to the section requiring lubrication, the second and third steps described above can be omitted. In this case, the marking line of the second holding device 120 is not necessary, and the fourth step can be carried out following the first step, and the insertion section 121 of the second holding device 120 can be inserted into the insertion hole of the first holding device 110 continuously until the stopper section 122 rests against the first holding device 110.

[0072] As described above, according to the lubrication device 100 of the first embodiment, it is possible to lubricate the pressure section 21a of the release fork 21 without removing the clutch housing 30 (or a transmission unit comprising the clutch housing 30) from the vehicle. This facilitates maintenance lubrication work and improves machinability. Second embodiment

[0073] The following describes an introduction amount recording device 100A of a second embodiment (reference example).

[0074] The Fig. Figures 12A to 12C are schematic views of the entry amount detection device of the second embodiment. Fig. Figures 12A to 12C show states in which the second holding device 120 is inserted into the first holding device 110 in this sequence.

[0075] The insertion amount detection device 100A is a device for visually detecting, from outside the coupling housing 30, the required insertion amount (hereinafter also referred to as the required insertion amount) of the second holding device 120 with respect to the first holding device 110, until the tip end section 131 of the lubrication line 130 reaches a position P1 near the corresponding section C or a position P2 (see Fig. 9), which has reached a predetermined distance from the corresponding section C.

[0076] The insertion amount detection device 100A has the same configuration as the lubrication device 100 of the first embodiment. However, the insertion amount detection device 100A differs from the lubrication device 100 of the first embodiment in that the insertion section 121 of the second holding device 120 has a first marking line L1 and a second marking line L2.

[0077] The differences compared to the first embodiment are described below, and configurations identical to those of the first embodiment are designated with the same reference numerals, with a description of these omitted where necessary. In the following description, as described in the first embodiment, the first retaining device 110 is attached to the coupling housing 30 (the circumferential section of the through-hole 31) in a state in which it is positioned in the X, Y, and Z directions with respect to the coupling housing 30.

[0078] The first holding device 110 and the second holding device 120 are made of resin or metal.

[0079] As it is in Fig. As shown in Figure 12A, the insertion section 121 of the second holding device 120 is inserted into the first hole 113 (or the second hole 114) formed in the first holding device 110 and is inserted in the direction of arrow AR4 into the corresponding section C (see Figure 12A). Fig. 9) in a state in which the operator has grasped the second holding device 120. With the insertion of the second holding device 120 into the corresponding section C, the tip end section 131 of the lubrication line 130 finally reaches position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C and the position P1 (see Fig. 9) is near the corresponding section C.

[0080] In this way, in order to visually detect the required insertion amount of the second holding device 120 with respect to the first holding device 110, until the tip end section 131 of the lubrication line 130 reaches position P2 (see Fig. 9) reached, which is the predetermined distance from the corresponding section C and the position P1 (see Fig. 9) is near the corresponding section C, as described in Fig. As shown in Figure 12A, the first marking line L1 and the second marking line L2 are attached to the insertion section 121 of the second holding device 120. Instead of the marking lines L1 and L2, a mark drawn with a magic marker or a sticker can be attached to the insertion section 121 of the second holding device 120.

[0081] The first marking line L1 is provided at a position where, when the tip end section 131 of the lubrication line 130 reaches position P2 (see Fig. 9) reached, which is the predetermined distance from the corresponding section C (if the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship), the first marking line L1 reaches the first holding device 110 (for example, a guide flange F provided on the first holding device 110) (for example, overlaps with the guide flange F) (see Fig. 12B).

[0082] Therefore, by visually confirming the spatial relationship between the first marking line L1 and the first holding device 110 (for example, the guide flange F provided on the first holding device 110) from outside the coupling housing 30, the operator can determine the required insertion amount of the second holding device 120 relative to the first holding device 110 until the tip end section 131 of the lubrication line 130 reaches position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C.

[0083] The second marking line L2 is placed at a position where, when the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) in the vicinity of the corresponding section C (if the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship), the second marking line L2 (for example, overlapping with the guide flange F) reaches the first holding device 110 (for example, the guide flange F arranged on the first holding device 110) (see Fig. 12C).

[0084] Therefore, by visually confirming the spatial relationship between the second marking line L2 and the first holding device 110 (for example, the guide flange F arranged on the first holding device 110) from outside the coupling housing 30, the operator can determine the required insertion amount of the second holding device 120 relative to the first holding device 110 until the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) reached near the corresponding section C, capture.

[0085] The marking line L1 can be omitted.

[0086] As described above, according to the second embodiment, the required insertion amount of the second holding device 120 relative to the first holding device 110 can be increased until the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) near the corresponding section C or position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C, is reached, and can be visually detected from outside the coupling housing 30.

[0087] Furthermore, the second embodiment offers the following advantages. That is, the required insertion length (stroke) until the tip end section 131 of the lubrication line 130 reaches the vicinity of the corresponding section C can vary for each vehicle model (for each transmission unit). In this case, for each vehicle model with a different required insertion length (for each transmission unit), the insertion section 121 of the second retaining device 120 has a marking (for example, a marking line, a line drawn with a marker, or a sticker) that aligns with the first retaining device 110 (for example, the guide flange F provided on the first retaining device 110) when the tip end section 131 of the lubrication line 130 reaches the vicinity of the corresponding section C.Consequently, it is possible to lubricate several vehicle models (multiple manual transmission units) with different required application amounts by using a single initial holding device 110. That is, since it is not necessary to prepare the initial holding device 110 for each vehicle model (for each manual transmission unit), it is possible to avoid an increase in the number of types of initial holding devices 110 and a corresponding increase in investment (costs). Third embodiment

[0088] The following describes an introduction amount recording device 100B of a third embodiment (reference example).

[0089] The Fig. Figures 13A to 13B are schematic views of the entry amount recording device of the third embodiment. Fig. Figures 13A to 13B show states in which the second holding device 120 is inserted into the first holding device 110.

[0090] The input amount detection device 100B is a device for detecting the fact that (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship) the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) near the corresponding section C, by hand (feeling of the hand holding the second holding device 120) rather than visually.

[0091] The insertion amount detection device 100B has the same configuration as the lubrication device 100 of the first embodiment. However, the insertion amount detection device 100B differs from the lubrication device 100 of the first embodiment in that the insertion section 121 of the second holding device 120 comprises first projections p1a, p1b.

[0092] The differences compared to the first embodiment are described below, and configurations identical to those of the first embodiment are designated with the same reference numerals, with a description of these omitted where necessary. In the following description, the first holding device 110, as described in the first embodiment, is attached to the coupling housing 30 (the circumferential section of the through-hole 31) in a state in which it is positioned in the X, Y, and Z directions with respect to the coupling housing 30.

[0093] At least one of the first holding device 110 and the second holding device 120 is made of resin. If one is made of resin, the other can be made of resin or metal.

[0094] As it is in Fig. As shown in Figure 13A, the insertion section 121 of the second holding device 120 is inserted into the first hole 113 (or the second hole 114) formed in the first holding device 110 and is inserted in the direction of arrow AR5 into the corresponding section C (see Figure 13A). Fig. 9) in a state in which the operator has grasped the second holding device 120. With the insertion of the second holding device 120 into the corresponding section C, the tip end section 131 of the lubrication line 130 finally reaches position P1 (see Fig. 9) near the corresponding section C.

[0095] In order to perceive in this way not visually, but by hand (the feeling of the hand holding the second holding device 120) that the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) in the vicinity of the corresponding section C (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship), the first projections p1a, p1b are provided on the introduction section 121 of the second holding device 120.

[0096] The first projections p1a, p1b are, for example, hemispherical projections. However, the first projections p1a, p1b are not limited to hemispherical shapes, but can be projections of other shapes.

[0097] If the second retaining device 120 is inserted into the first hole 113 (or the second hole 114) (see Fig. 13B) is introduced into the corresponding section C and the tip end section 131 of the lubrication line 130 is at position P1 (see Fig. 9) in the vicinity of the corresponding section C, the first projections p1a, p1b are located at positions where they cause friction (friction force) with the first hole 113 (or the second hole 114).

[0098] To create this friction, as described in Fig. As shown in Figure 13A, the diameter A2 (nominal dimension) of the first hole 113 (and of the second hole 114) and the thickness B2 (nominal dimension) of the insertion section 121 of the second holding device 120 with the first projections p1a, p1b are set such that they satisfy the relationship A2 < B2.

[0099] Therefore, by inserting the second holding device 120 into the corresponding section C, the operator can perceive by hand (feel of the hand holding the second holding device 120) rather than visually that (the friction described above) the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) near the corresponding section C.

[0100] As described above, according to the third embodiment, the fact that the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) in the vicinity of the corresponding section C (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship) can be detected not visually, but by hand (feel of the hand holding the second holding device 120).

[0101] This is because the first projections p1a, p1b are located in positions where they cause friction (a frictional force) with the first hole 113 (or the second hole 114) when the second holding device 120 is inserted into the first hole 113 (or the second hole 114) (see Fig. 13B) is introduced in the direction of the corresponding section C and the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) is reached near the corresponding section C (if the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship).

[0102] Therefore, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C)) displayed on the display section 163, which is attached to the actuating section 162 that he has grasped with one hand (for example, the right hand), the operator can concentrate on inserting the second holding device 120 (insertion section 121), which he grasps with the other hand (for example, the left hand), into the corresponding section C in the direction of arrow AR5, so that the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) near the corresponding section C.

[0103] Furthermore, the second embodiment offers the following advantages. As described above, the friction generated between the first projections p1a, p1b and the inner wall of the first hole 113 (or the second hole 114) causes the second retaining device 120 to be attached to the first retaining device 110 when the first projections p1a, p1b are inserted into the first hole 113 (or the second hole 114). Furthermore, the gap (clearance) between the insertion section 121 of the second retaining device 120, inserted into the first hole 113 (or the second hole 114), and the inner wall of the first hole 113 (or the second hole 114) is approximately 0.5 mm.

[0104] Therefore, when the described friction occurs, the position of the tip end section 131 of the lubrication line 130 with respect to the corresponding section C does not change (almost not), even if the operator releases the second holding device 120.

[0105] Therefore, if the friction described above occurs, that is, if the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) near the corresponding section C, by releasing the other hand (for example, the left hand) that previously held the second holding device 120, and re-grasping and operating the lubrication device 150 with the other, free hand (for example, the left hand) (for example, the one in Fig. (3. Push rod 152 shown in its axial direction), grease is supplied from the opening section 131a of the lubrication line 130 to the corresponding section C. That is, a single operator can insert the second holding device 120 into the corresponding section C and then supply grease from the opening section 131a of the lubrication line 130 to the corresponding section C. This improves work efficiency. Fourth embodiment

[0106] The following describes an introduction amount recording device 100C of a fourth embodiment (reference example).

[0107] The Fig. Figures 14A to 14C are schematic views of the entry amount detection device of the fourth embodiment. Fig. Figures 14A to 14C show states in which the second holding device 120 is inserted into the first holding device 110.

[0108] The introduction amount detection device 100C is a device for detecting the fact that the tip end section 131 of the lubrication line 130 is in position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C or position P1 (see Fig. 9) near the corresponding section C (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship) is reached by hand (feeling of the hand holding the second holding device 120) rather than visually.

[0109] The insertion amount detection device 100C has the same configuration as the lubrication device 100 of the first embodiment. However, the insertion amount detection device 100C differs from the lubrication device 100 of the first embodiment in that first projections p1a, p1b are arranged on the insertion section 121 of the second holding device 120 and second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are arranged on the inner wall of the first hole 113 (and the second hole 114) formed in the first holding device 110.

[0110] The differences compared to the first embodiment are described below, and configurations identical to those of the first embodiment are designated with the same reference numerals, with their description omitted where necessary. In the following description, the first holding device 110, as described in the first embodiment, is attached to the coupling housing 30 (the circumferential section of the through-hole 31) in a state in which it is positioned in the X, Y, and Z directions with respect to the coupling housing 30.

[0111] At least one of the first holding device 110 and the second holding device 120 is made of resin. If one is made of resin, the other can be made of resin or metal.

[0112] As it is in Fig. As shown in Figure 14A, the insertion section 121 of the second holding device 120 is inserted into the first hole 113 (or the second hole 114) formed in the first holding device 110 and is inserted in a state in the direction of arrow AR6 into the corresponding section C (see Figure 14A). Fig. 9) introduced, in which the second holding device 120 is grasped by the operator. With the insertion of the second holding device 120 into the corresponding section C, the tip end section 131 of the lubrication line 130 finally reaches position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C, and then the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) near the corresponding section C.

[0113] In this way, the introductory section 121 of the second holding device 120 includes, in order to perceive not visually, but by hand (the feeling of the hand holding the second holding device 120), that the tip end section 131 of the lubrication line 130 is in position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C, and the position P1 (see Fig. 9) in the vicinity of the corresponding section C (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship), the first projections p1a, p1b are reached. Furthermore, the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first retaining device 110.

[0114] The first projections p1a, p1b and the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are, for example, hemispherical projections. However, the first projections p1a, p1b and the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are not limited to hemispherical shapes, but can be projections of other shapes.

[0115] The first projections p1a, p1b are arranged at positions where they are inserted into the first hole 113 (or the second hole 114) when the tip end section 131 of the lubrication line 130 is inserted into the corresponding section C at position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C, and then the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) reached near the corresponding section C (see the Fig. 14B and Fig. 14C).

[0116] The second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are in a row in the introduction direction (see the arrow AR6 in Fig. 14) the second holding device 120 arranged.

[0117] The first projections p1a and p1b pass through the respective second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3), while by inserting the second holding device 120 into the corresponding section C they cause friction with the second projections p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3).

[0118] To cause this friction, as described in Fig. Figure 14A shows a diameter A3 (nominal size) of the first hole 113 (and of the second hole 114) which includes the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3), and a thickness B3 (nominal size) of the insertion section 121 of the second retaining device 120 which includes the first projections p1a, p1b, such that they satisfy the relationship A3 < B3.

[0119] Therefore, by inserting the second holding device 120 into the corresponding section C, the operator can perceive by hand (the feeling of the hand holding the second holding device 120) rather than visually (the friction described above) that the tip end section 131 of the lubrication line 130 is in position P2 (see Fig. 9), which is the predetermined distance from the corresponding section C, and then the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) in the vicinity of the corresponding section C. For example, if the first projections p1a, p1b pass through the second projections p2a1, p2b1 while bearing against (or being pressed into) the second projection p2a1, p2b1 by inserting the second holding device 120 into the corresponding section C, the operator can perceive that (due to the friction described above) the tip end section 131 of the lubrication line 130 reaches position P2 (see Fig. 9), which is a predetermined distance from the corresponding section C, is reached, not visually, but by hand (the feel of the hand holding the second holding device 120). Furthermore, when the first projections p1a, p1b pass through the second projections p2a2, p2b2, while bearing against (or pressing into) the second projections p2a2, p2b2 by further insertion of the second holding device 120 into the corresponding section C, the operator can perceive that (the friction described above) the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) near the corresponding section C, not visually, but by hand (the feeling of the hand holding the second holding device 120).

[0120] As described above, according to the fourth embodiment, the fact that the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) in the vicinity of the corresponding section C (the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship) can be detected not visually, but by hand (the feeling of the hand holding the second holding device 120).

[0121] This is due to the fact that the first projections p1a, p1b and the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are arranged at positions where both projections cause friction (a frictional force) when the tip end section 131 of the lubrication line 130 is at position P2 (see Fig. 9) is reached, which is the predetermined distance from the corresponding section C, and then the tip end section 131 of the lubrication line 130 is inserted into the corresponding section C by inserting the second holding device 120 into the corresponding section C (if the tip end section 131 of the lubrication line 130 and the corresponding section C have a predetermined spatial relationship) the position P1 (see Fig. 9) near the corresponding section C.

[0122] Therefore, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130 and its surroundings (for example, the corresponding section C)) displayed on the display section 163, which is attached to the actuating section 162 held with one hand (for example, the right hand), the operator can concentrate on inserting the second holding device 120 (insertion section 121), which he holds with the other hand (for example, the left hand), into the corresponding section C in the direction of arrow AR6, so that the tip end section 131 of the lubrication line 130 reaches position P2 (see Fig. 9) is reached, which is the predetermined distance from the corresponding section C, and the tip end section 131 of the lubrication line 130 then reaches position P1 (see Fig. 9) near the corresponding section C.

[0123] Furthermore, the fourth embodiment offers the following advantages. As described above, the second holding device 120 is in a state where it is attached to the first holding device 110 when the tip end section 131 of the lubrication line 130 is in position P1 (see Figure 1). Fig. 9) is reached near the corresponding section C and the first projections p1a, p1b are introduced into the first hole 113 (or the second hole 114) (see Fig. 14C). Furthermore, the gap (free space) between the insertion section 121 of the second retaining device 120 inserted into the first hole 113 (or the second hole 114) and the inner wall of the first hole 113 (or the second hole 114) is approximately 0.5 mm.

[0124] Therefore, when the tip end section 131 of the lubrication line 130 reaches position P1 (see Fig. 9) is reached near the corresponding section C and the first projections p1a, p1b are introduced into the first hole 113 (or the second hole 114) (see Fig. 14C), the position of the tip end section 131 of the lubrication line 130 with respect to the corresponding section C does not (or hardly) change, even when the operator releases the second holding device 120 with the hand that is holding the second holding device 120.

[0125] Therefore, if the tip end section 131 of the lubrication line 130 is in position P1 (see Fig. 9) near the corresponding section C, by releasing the second holding device 120 with the other hand (for example, the left hand) that is holding the second holding device 120, and re-grasping and operating the lubrication device 150 with the other, free hand (for example, the left hand) (for example, by pressing the in Fig. 3. Push rod 152 (shown in its axial direction), grease from the opening section 131a of the lubrication line 130 is supplied to the corresponding section C. That is, a single operator can first insert the second holding device 120 into the corresponding section C and then supply grease from the opening section 131a of the lubrication line 130 to the corresponding section C. This improves work efficiency.

[0126] Furthermore, the fourth embodiment offers the following advantages. The required insertion length (stroke) until the tip end section 131 of the lubrication line 130 reaches the area of ​​the corresponding section C can differ for each vehicle model (for each transmission unit). In this case, for each vehicle model with a different required insertion length (for each transmission unit), the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are arranged such that friction (the frictional force) occurs when the tip end section 131 of the lubrication line 130 reaches the area of ​​the corresponding section C. Consequently, it is possible to lubricate several vehicle models (several transmission units) with different required insertion lengths by using a first holding device 110.Since it is not necessary to prepare the first holding device 110 for each vehicle model (for each manual transmission unit), it is possible to avoid an increase in the types of the first holding device 110 and a corresponding increase in investment (costs).

[0127] The following is a modification example. Fig. Figure 15 is a schematic view of the introduction amount recording device (modification example) of the fourth embodiment.

[0128] As it is in Fig. Figure 14A shows an example in the fourth embodiment in which the first projections pa1, pb1 are provided in the introductory section 121 of the second holding device 120 and the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first holding device 110. However, the present invention is not limited to this.

[0129] As it is in Fig. As shown in Figure 15, for example, the second projections p2a (p2a1, p2a2, p2a3), p2b (p2b1, p2b2, p2b3) can be provided in the introduction section 121 of the second holding device 120 and the first projections pa1, pb1 on the inner wall of the first hole 113 (and the second hole 114) formed in the first holding device 110.

[0130] Furthermore, the fourth embodiment describes an example in which three second projections p2a (p2a1, p2a2, p2a3) are used on one side and three second projections p2b (p2b1, p2b2, p2b3) are used on the other side. However, the present invention is not limited to this. For example, four or more second projections p2a can be used on one side and four or more second projections p2b on the other side.

[0131] Modification examples of the first to fourth embodiments are described below.

[0132] The first to fourth embodiments described above illustrate the example in which fat is used as a fluid substance. However, the present invention is not limited to this. For example, a fluid can be used as the fluid substance. In this case, the corresponding section C is the section to which the fluid must be supplied. Furthermore, a fluid substance other than fat or fluid can be used as the fluid substance.

[0133] Furthermore, the third and fourth embodiments describe an example in which the first projections p1a, p1b are arranged in the introductory section 121 of the second retaining device 120. However, the present invention is not limited to this. For example, the first projections p1a, p1b can be provided on the lubrication line 130 if the second retaining device 120 is omitted.

[0134] Furthermore, the first to fourth embodiments described above describe an example in which the lubrication line 130 is arranged in the second holding device 120. However, the present invention is not limited to this. For example, the lubrication line 130 can be omitted. In this way, the endoscope 160 can be used to inspect confined spaces. In this case, the corresponding section C is a location that requires a constriction inspection. Furthermore, the first to fourth embodiments described above describe examples in which the endoscope 160 is arranged in the second holding device 120. However, the present invention is not limited to this. For example, the endoscope 160 can be omitted.

[0135] Furthermore, the first to fourth embodiments describe examples in which the injection quantity detection device of the present invention is applied to the field of vehicles (grease injection maintenance of the clutch release mechanism). However, the present invention is not limited to this. For example, the injection quantity detection device of the present invention can be applied to various other fields besides vehicles, such as medicine. For example, the first to fourth embodiments described above describe examples in which the clutch housing 30 (the circumferential section of the through-hole 31) is used as a fixing target element. However, the present invention is not limited to this.This means that a fixing target element corresponding to the area to which the input amount detection device of the present invention is applied can be used. Accordingly, the examples in which the coupling housing 30 is used as the cover element are described in the first to fourth embodiments. However, the present invention is not limited to this. That is to say, a cover element corresponding to the area to which the input amount detection device of the present invention is applied can be used. Fifth embodiment

[0136] The following describes an injection device of a fifth embodiment (reference example).

[0137] Fig. 16 is a configuration view of an injection device 100A.

[0138] The injection device 100A of the fifth embodiment differs from that of the first embodiment in that it essentially does not include the first holding device 110 and the second holding device 120, but does include a holding element 170. The differences compared to that of the first embodiment are described below, and the same components as those of the first embodiment are designated with the same reference numerals, their descriptions being omitted where necessary.

[0139] Similar to the first embodiment, the injection device 100A of the fifth embodiment comprises an introductory section 180 (see Fig. 16), which is inserted into the corresponding section C in a confined space while being grasped by an operator. The insertion section 180 comprises a lubrication line 130A, an endoscope 160A, and a retaining element 170. Similar to the first embodiment, the following is an example of a case in which the confined space is a lubrication point (a point to which grease must be supplied from the tip end section 131 of the lubrication line 130A) between the release fork 21 (the pressure section 21a) and the release bearing 15. One end face of the release fork 21 comprises a pressure section 21a that presses the release bearing 15 in the axial direction (see Fig. 22) presses. The pressure section 21a has a forked structure in which the tip end is forked in such a way that it clamps the input shaft 3 in the clutch housing 30. In Fig. Section C on the front side is shown in Figure 22. The corresponding section C on the rear side is located behind the release bearing 15 and is not shown.

[0140] The lubrication line 130A, similar to the lubrication line 130 of the first embodiment, is a long injection section comprising a tipped end section 131 from which grease (an example of the fluid substance of the present invention) is injected. This lubrication line 130A is made of metal. To facilitate the insertion of the tipped end section 131 of the lubrication line 130 into a section between the release fork 21 (the pressure section 21a) and the release bearing 15, which is the section requiring lubrication, the tipped end section 131 of the lubrication line 130A has a square, cylindrical shape with a horizontally long, rectangular cross-section (see Figure 1). Fig. 16) The lubrication line 130A has a cylindrical shape except for the tip section 131. The lubrication line 130A can have a cylindrical shape including the tip section 131.

[0141] The internal structure of the clutch housing 30 can vary depending on the vehicle model (for each manual transmission unit). Depending on the internal structure of the clutch housing 30, the insertion path of the insertion section 180 (the lubrication line 130A and the endoscope 160A) from the through-hole 31 of the clutch housing 30 into the corresponding section C can be linear, or the insertion path can include one or more curved sections in the middle.

[0142] In the latter case, if the lubrication line 130A extends linearly like the lubrication line 130 of the first embodiment, the insertion section 180 (the lubrication line 130A and the endoscope 160A) collides with the obstruction in the coupling housing 30. Therefore, it is difficult to insert the insertion section 180 (the lubrication line 130A and the endoscope 160A) into the corresponding section C.

[0143] Therefore, in the fifth embodiment, assuming that the insertion path of the insertion section 180 (of the lubrication line 130A and the endoscope 160A) includes a curved section in the middle, a section C1 is curved between the base end section and the tip end section. This makes it relatively easy to insert the insertion section 180 (of the lubrication line 130A and the endoscope 160A) into the corresponding section C, even if there is a curved section in the middle of the path through which the insertion section 180 (of the lubrication line 130A and the endoscope 160A) is inserted. Depending on the path through which the insertion section 180 (of the lubrication line 130A and the endoscope 160A) is inserted, the lubrication line 130A can be curved at several points between the base end section and the tip end section.

[0144] The tip end section 131 (the tip end face) of the lubrication line 130A includes an injection port 131a for injecting grease, which is supplied through a cylindrical section of the line. A flexible line 140 is connected to the base end of the lubrication line 130A. The lubrication line 130 is connected to the lubrication device 150 via the flexible line 140.

[0145] The endoscope 160A is a long imaging device with an imaging unit for capturing an image encompassing the tip end section 131 of the lubrication line 130A and its surroundings (for example, the corresponding section C) within the tip end section 160A. The endoscope 160A has a cylindrical shape with a larger diameter than the lubrication line 130A, and a section C2 between the base end section and the tip end section is bent at the same angle as the lubrication line 130A. Similar to the lubrication line 130A, the endoscope 160A can be bent at several points between the base end section and the tip end section, depending on the path through which the insertion section 180 (the lubrication line 130A and the endoscope 160A) is inserted.

[0146] The base end of the endoscope 160A is connected to the actuating section 162 via the cable 161. By actuating the actuating section 162, it is possible to capture an image of the internal structure of the coupling housing 30 with the endoscope 160A. The image captured by the endoscope 160A (for example, the image showing the tip end section 131 of the lubrication line 130A and its surroundings (for example, the corresponding section C)) can be displayed on the display section 163, which is attached to the actuating section 162.

[0147] The retaining element 170 is described below.

[0148] As it is in Fig. As shown in Figure 16, the retaining element 170 holds the lubrication line 130A and the endoscope 160A parallel and next to each other.

[0149] Fig. 17 is a cross-sectional view along line XVII-XVII of Fig. 16, and Fig. Figure 18 is a perspective view of the holding element 170.

[0150] As it is in the Fig. 17 and Fig. As shown in Figure 18, the retaining element 170 comprises an injection section insertion section 171 into which the lubrication line 130A (the cylindrical section on the side of the base end section) is pressed, an imaging unit insertion section 172 into which the endoscope 160A (the cylindrical section on the side of the base end section) is pressed, and a first connecting section 173 that connects the injection section insertion section 171 to the imaging unit insertion section 172.

[0151] The injection section insertion section 171 is a first semi-cylindrical section into which a lubrication line 130A (the cylindrical section on the side of the base end section) is pressed. The imaging unit insertion section 172 is a second semi-cylindrical section into which the endoscope 160A (the cylindrical section on the side of the base end section) is pressed. The first connecting section 173 is a flat section that connects an end section of the first semi-cylindrical section (injection section insertion section 171) to an end section of the second semi-cylindrical section (imaging unit insertion section 172). Hereinafter, the first connecting section 173 will also be referred to as a flat section 173.This flat section (the first connecting section 173) extends in a tangential direction to the first semi-cylindrical section (the injection section introduction section 171) and the second semi-cylindrical section (the imaging unit introduction section 172) (see . Fig. 17).

[0152] The first semi-cylindrical section (the injection section introduction section 171) is formed by bending back a first end section of the plate into a semi-cylindrical shape. Similarly, the second semi-cylindrical section (the imaging unit introduction section 172) is formed by bending back a second end section of the plate into a semi-cylindrical shape. The first connecting section 173 is a plate section between the first semi-cylindrical section (the injection section introduction section 171) and the second semi-cylindrical section (the imaging unit introduction section 172).

[0153] The retaining element 170 (the plate) is made of synthetic resin or spring steel. That is, the retaining element 170 can be formed by injection molding a synthetic resin or by bending or pressing a plate-shaped piece of spring steel.

[0154] An axial length L (see Fig. 18) of the retaining element 170 is set to a length (for example L = 40 mm) which is suitable for connecting the lubrication line 130A to the endoscope 160A.

[0155] The diameter of the injection section insertion section 171 is slightly larger than the diameter of the lubrication line 130A. Therefore, the injection section insertion section 171 is elastically deformed when the lubrication line 130A is inserted and is attached to the lubrication line 130A (the cylindrical section on the side of the base end section) in a state where, due to its restoring force, it is in close contact with the outer circumferential surface of the lubrication line 130A (the cylindrical section on the side of the base end section).

[0156] Accordingly, the diameter of the imaging unit insertion section 172 is slightly larger than the diameter of the endoscope 160A. Therefore, when the endoscope 160A is inserted, the imaging unit insertion section 172 is elastically deformed and is attached to the endoscope 160A (the cylindrical section on the side of the base end section) in a state where it is in close contact with the outer circumferential surface of the endoscope 160A (the cylindrical section on the side of the base end section) due to its restoring force.

[0157] Fig. Figure 19 is a perspective view of lubrication line 130A (the cylindrical section on the side of the base end section).

[0158] As it is in Fig. As shown in Figure 19, the outer circumferential surface of the lubrication line 130A comprises a first marking line L1 and a second marking line L2 extending in the axial direction. The marking lines L1 and L2 are used to position the endoscope 160A at a suitable angular position relative to the lubrication line 130A. This is described below. The marking lines L1 and L2 are examples of the markings on the side of the injection section of the present invention. The markings on the side of the injection section are not limited to the marking lines L1 and L2, but can also be other markings besides lines drawn with a magic marker or a sticker, which may be applied to the outer circumferential surface of the lubrication line 130A.

[0159] The following is a lubrication procedure using the 100A injection device with reference to the Fig. described in sections 20 to 22. Fig. 20 and Fig. Figure 21 shows a state in which the insertion section 180 is inserted into the through-hole 31 of the clutch housing 30 to supply grease to the corresponding section C on the front. Fig. Figure 20 is a view of the through hole 31 from a direction opposite to arrow AR4 in Fig. 22 considered. Fig. Figure 22 is a view showing a condition in which the lubrication line 130A extends in the direction of the corresponding section C on the front, in which the insertion section 180 is inserted into the through hole 31 of the coupling housing 30.

[0160] The fork shoe 32 is removed before the following steps are carried out. As a result, the through hole 31 (see Fig. 21 and the like) of the coupling housing 30 for the insertion of the insertion section 180.

[0161] Below, in Fig. 22, is an example of the lubrication process described in the sequence of the corresponding section C on the front and the corresponding section C on the back. Fig. 22 the corresponding section C is located on the rear side behind the release bearing 15 and is not shown.

[0162] First, as a first step to avoid (and to ensure the field of view of the endoscope 160A) the insertion section 180 (the lubrication line 130A and the endoscope 160A) being inserted into the corresponding section C on the front, colliding with obstacles inside the coupling housing 30, the operator positions the endoscope 160A at a suitable angular position with respect to the lubrication line 130A according to the internal structure of the coupling housing 30.

[0163] This is done by rotating (see the AR5 arrow in Fig. 20) of the retaining element 170 is realized in a state in which the lubrication line 130A and the endoscope 160A are held with respect to the lubrication line 130A and a winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170 is connected to the first marking line L1 (see Fig. 19), which is attached to the outer circumferential surface of the lubrication line 130A, is brought into alignment (see Fig. 20).

[0164] The first marking line L1 is located at a position where the winding end section 174 on the side of the injection section insertion section 171 coincides with the first marking line L1 when the endoscope 160A is at a position of an angle θ1 (see Fig. 20) is arranged with respect to lubrication line 130A (reference line AX). In the case of Fig. 20, the angle θ1 is, for example, 75°. The winding end section 174 on the side of the injection section introduction section 171 is an example of the marking on the side of the retaining element of the present invention. However, the marking on the side of the retaining element is not limited to the winding end section 174 on the side of the injection section introduction section 171, but can be another marking, for example, a line drawn with a magic marker or a sticker affixed to the retaining element 170. The reference line AX extends in a direction parallel to the upper surface (see Fig. 16) of the square, cylindrical tip end section 131 of the lubrication line 130A (see Fig. 16).

[0165] Therefore, by visually confirming the spatial relationship between the winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170 and the first marking line L1, the operator can ascertain that the endoscope 160A is at the position of angle θ1 (see Fig. 20) with respect to lubrication line 130A (reference line AX).

[0166] Subsequently, as a second step, the operator inserts the insertion section 180, in which the endoscope 160A is arranged, through the through-hole 31 of the coupling housing 30 at the position of the angle θ1. The through-hole 31 of the coupling housing 30 is an example, according to the present invention, of "an opening section or a notched section formed in a wall section between the operator and the corresponding section." In this case, as shown in Fig. As shown in Figure 20, the introduction section 180 is introduced, while the imaging unit introduction section 172 of the retaining element 170 is brought into contact with a corner section (a right corner section in Fig. 20) is located, which corresponds to the corresponding section C on the front of the through-hole 31 of the coupling housing 30, that is, while the insertion direction of the insertion section 180 is guided into the corresponding section C on the front. As described above, in the fifth embodiment, the guiding function is realized by the corner section of the through-hole 31 of the coupling housing 30 and the imaging unit insertion section 172 of the retaining element 170.

[0167] The leadership function can be implemented as follows. Fig. Figure 23 is a view (modification example) showing a state in which the insertion section 180 is inserted into the through-hole 31 of the clutch housing 30 to supply grease to the corresponding section C on the front. That is, as shown in Fig. As shown in Figure 23, the introduction section 180 can be inserted, while not only the imaging unit introduction section 172 of the retaining element 170, but also the flat section 173 come into contact with the corner section (the right corner section in Figure 23). Fig. 23), which corresponds to the corresponding section C on the front of the through-hole 31 of the coupling housing 30. This is an example of the realization of the guiding function by the corner section of the through-hole 31 of the coupling housing 30, the imaging unit insertion section 172, and the flat section 173 of the retaining element 170. In the case of Fig. For example, in 23 the angle θ1 is 100°.

[0168] In the following steps, the operator, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130A and its surroundings (for example, the corresponding section C on the front)) displayed on the display section 163, which is attached to the actuating section 162, which he grasps with one hand (for example, the right hand), guides the insertion section 180, which he grasps with the other hand (for example, the left hand), in the direction of arrow AR4 (see Fig. 21 and Fig. 22) into the corresponding section C on the front side, so that the tip end section 131 of the lubrication line 130A reaches the corresponding section C on the front side.

[0169] With the insertion of the insertion section 180 into the corresponding section C on the front side, the tip end section 131 of the lubrication line 130A finally reaches a position P4 (see Fig. 22), which is a predetermined distance from the corresponding section C on the front side, and then reaches a position P3 (see Fig. 22) near the corresponding section C on the front.

[0170] In this way, the retaining element 170 is positioned to visually detect the required insertion amount until the tip end section 131 of the lubrication line 130A reaches position P4, which is the predetermined distance from the corresponding section C, and position P3 near the corresponding section C, as shown in Fig. As shown in Figure 16, the retaining element 170 is provided with a third marking line L3 and a fourth marking line L4. Instead of the marking lines L3 and L4, a marking such as a line drawn with a Magic Marker or a sticker can be applied to the retaining element 170.

[0171] The third marking line L3 is provided at a position where the third marking line L3 coincides with the through hole 31 of the coupling housing 30 when the tip end section 131 of the lubrication line 130A is at position P4 (see Fig. 22) is reached, which is the predetermined distance from the corresponding section C (if the tip end section 131 of the lubrication line 130A and the corresponding section C have a predetermined spatial relationship).

[0172] Therefore, by visually confirming the spatial relationship between the third marking line L3 and the through-hole 31 of the coupling housing 30, the operator can determine the required insertion amount until the tip end section 131 of the lubrication line 130A reaches position P4 (see Fig. 22) is reached, which is the predetermined distance from the corresponding section C. Furthermore, it can be determined that the tip end section 131 of the lubrication line 130A is at position P4 (see Fig. 22) has reached, which is the predetermined distance from the corresponding section C.

[0173] The fourth marking line L4 is provided at a position where the fourth marking line L4 coincides with the through hole 31 of the coupling housing 30 when the tip end section 131 of the lubrication line 130A is at position P3 (see Fig. 22) is reached near the corresponding section C (if the tip end section 131 of the lubrication line 130A and the corresponding section C have a predetermined spatial relationship).

[0174] Therefore, by visually confirming the spatial relationship between the fourth marking line L4 and the through-hole 31 of the coupling housing 30, the operator can determine the required insertion amount until the tip end section 131 of the lubrication line 130 reaches position P3 (see Fig. 22) in the vicinity of the corresponding section C. Furthermore, it can be determined that the tip end section 131 of the lubrication line 130 reaches position P3 (see Fig. 22) near the corresponding section C.

[0175] The third marking line L3 can be omitted.

[0176] Then, when the fourth marking line L4 coincides with the through hole 31 of the coupling housing 30, that is, when the tip end section 131 of the lubrication line 130A reaches position P3 (see Fig. 22) near the corresponding section C on the front, the operator, as a third step (see Fig. 22), the tip end section 131 of the lubrication line 130 between the release fork 21 (the pressure section 21a) and the release bearing 15, and supplies grease to the corresponding section C on the front from the injection port 131a of the lubrication line 130A. In particular, the operator, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130A and its surroundings (for example, the corresponding section C on the front)) displayed on the display section 163 attached to the actuating section 162, which he grasps with one hand (for example, the right hand), grasps the lubrication device 150 with the other hand (for example, the left hand) and actuates it (for example, presses the in Fig. 16 shown push rod 152 in its axial direction) it to the corresponding section C (see Fig. 22) to supply grease to the front of the injection port 131a of the lubrication line 130A.

[0177] Then, when the supply of grease to the corresponding section C on the front is complete, the operator, as a fourth step, removes the lubrication line 130A from the through-hole 31 of the coupling housing 30.

[0178] Then, as a fifth step, the operator positions the endoscope 160A at a suitable angular position with respect to the lubrication line 130A according to the internal structure of the coupling housing 30 in order to avoid (and to ensure the field of view of the endoscope 160A) the insertion section 180 (the lubrication line 130A and the endoscope 160A) being inserted into the corresponding section C on the rear side colliding with obstacles inside the coupling housing 30.

[0179] This is done by rotating (see the AR2 arrow in Fig. 24) of the retaining element 170 is realized in a state in which the lubrication line 130A and the endoscope 160A are held relative to the lubrication line 130A and the winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170 is aligned with the second marking line L2 (see Fig. 19), which is attached to the outer circumferential surface of lubrication line 130A, is brought into conformity (see Fig. 24). Fig. Figure 24 is a view showing a state in which the insertion section 180 is inserted into the through-hole 31 of the clutch housing 30 to supply grease to the corresponding section C on the rear side. Fig. Figure 24 is a view of the through hole 31, viewed from the direction opposite to arrow AR4 in Fig. 22.

[0180] The second marking line L2 is provided at a position where the winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170 coincides with the second marking line L2 when the endoscope 160A is at a position of an angle θ2 (see Fig. 24) is arranged with respect to lubrication line 130A (reference line AX). In the case of Fig. For example, in 24 the angle θ2 is 75°.

[0181] Therefore, by visually confirming the spatial relationship between the winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170 and the second marking line L2, the operator can ascertain that the endoscope 160A is at the position of angle θ2 (see Fig. 24) with respect to lubrication line 130A (reference line AX).

[0182] Then, as a sixth step, the operator inserts the insertion section 180, in which the endoscope 160A is positioned at the angle θ2, through the through-hole 31 of the coupling housing 30. In this case, as shown in Fig. As shown in Figure 24, the introduction section 180 is introduced, while the imaging unit introduction section 172 of the retaining element 170 comes into contact with a corner section (a left corner section in Fig. 24) is held, which corresponds to the corresponding section C on the rear side of the through-hole 31 of the coupling housing 30, that is, while the insertion direction of the insertion section 180 is guided into the corresponding section C on the rear side. As described above, in the fifth embodiment, the guiding function is realized by the corner section of the through-hole 31 of the coupling housing 30 and the imaging unit insertion section 172 of the retaining element 170.

[0183] The leadership function can be implemented as follows. Fig. Figure 25 is a view (a modification example) showing a state in which the insertion section 180 is inserted into the through-hole 31 of the clutch housing 30 to supply grease to the corresponding section C on the rear. That is, as shown in Fig. As shown in Figure 25, the introductory section 180 can be introduced, while the imaging unit introductory section 172 of the retaining element 170, which is shown in Fig. The right-left reversed retaining element 170 shown in 20 is in contact with the corner section (the left corner section in Fig. 25) is held, which corresponds to the corresponding section C on the rear side of the through-hole 31 of the coupling housing 30. This is achieved by performing a process between the fourth and fifth steps in which the lubrication line 130A and the endoscope 160A are removed from the holding element 170, the holding element 170 is reversed from right to left, and the lubrication line 130A and the endoscope 160A are again held with the holding element 170, which has been reversed from right to left.

[0184] Furthermore, the leadership function can be implemented as follows. Fig. Figure 26 is a view (modification example) showing a state in which the insertion section 180 is inserted into the through-hole 31 of the clutch housing 30 to supply grease to the corresponding section C on the rear side. That is, as shown in Fig. As shown in Figure 26, the introduction section 180 can be inserted, while not only the imaging unit introduction section 172 of the retaining element 170, but also the flat section 173 come into contact with the corner section (the left corner section in Fig. 26) is located, which corresponds to the corresponding section C on the rear side of the through-hole 31 of the coupling housing 30. This is an example of the realization of the guiding function by the corner section of the through-hole 31 of the coupling housing 30, the imaging unit insertion section 172, and the flat section 173 of the retaining element 170. In the case of Fig. For example, in 26 the angle θ2 is 100°.

[0185] In the following steps, the operator, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130A and its surroundings (for example, the corresponding section C on the rear)) displayed on the display section 163, which is attached to the actuating section 162, which he has grasped with one hand (for example, the right hand), inserts the insertion section 180, grasped with the other hand (for example, the left hand), into the corresponding section C on the rear, so that the tip end section 131 of the lubrication line 130A reaches the corresponding section C on the rear.

[0186] With the insertion of the insertion section 180 into the corresponding section C on the back, the tip end section 131 of the lubrication line 130A finally reaches position P4 (see Fig. 22), which is the predetermined distance from the corresponding section C on the reverse side, and then position P3 (see Fig. 22) near the corresponding section C on the reverse side.

[0187] Then, when the fourth marking line L4 coincides with the through hole 31 of the coupling housing 30, that is, when the tip end section 131 of the lubrication line 130A is at position P3 (see Fig. 22) near the corresponding section C on the rear side, the operator, as a seventh step, inserts the tip end section 131 of the lubrication line 130 between the release fork 21 (pressure section 21a) and the release bearing 15 and supplies grease to the corresponding section C on the rear side from the injection port 131a of the lubrication line 130A. Specifically, while paying close attention to the screen (an image containing the tip end section of the lubrication line 130A and its surroundings (for example, the corresponding section C on the rear side)) displayed on the display section 163 attached to the actuating section 162, which is gripped with one hand (for example, the right hand), the operator grasps the lubrication device 150 with the other hand (for example, the left hand) and actuates it (for example, presses the Fig. 16 push rod 152 shown in its axial direction) it, to supply grease from the injection port 131a from the lubrication line 130A to the corresponding section C on the rear.

[0188] Then, when the supply of grease to the corresponding section C on the rear is complete, the operator, as an eighth step, removes the lubrication line 130A from the through-hole 31 of the coupling housing 30.

[0189] Performing each of the above steps completes the lubrication of the corresponding section C on the front and the corresponding section C on the back.

[0190] As described above, according to the fifth embodiment, the insertion section 180 can be inserted into the corresponding section C without using a guide holding device.

[0191] This is due to the fact that the guiding function is realized through the through-hole 31 (the corner section or the like) of the coupling housing 30 and the retaining element 170 (the imaging unit insertion section 172, the flat section 173).

[0192] Furthermore, according to the fifth embodiment, the endoscope 160A can be arranged at a suitable angular position with respect to the lubrication line 130A.

[0193] This is due to the retaining element 170, which holds the lubrication line 130A and the endoscope 160A parallel and adjacent to each other, and the lubrication line 130A with the marking (for example, the marking lines L1 and L2) on the side of the injection section, which corresponds to the marking (for example, the winding end section 174 on the side of the injection section insertion section 171 of the retaining element 170) on the side of the retaining element of the retaining element 170.

[0194] Furthermore, according to the fifth embodiment, it is possible to lubricate the pressure section 21a of the release fork 21 without removing the clutch housing 30 (or a transmission unit comprising the clutch housing 30) from the vehicle. This simplifies lubrication maintenance and improves machinability.

[0195] The following describes a first modification example of the retaining element 170 of the fifth embodiment.

[0196] Fig. Figure 27 is a perspective view of a holding element 170A, which is the first modification example, and Fig. 28 is a cross-sectional view along line XXVIII-XXVIII of Fig. 27.

[0197] As it is in the Fig. 27 and Fig. As shown in Figure 28, the retaining element 170A comprises a third semi-cylindrical section 175, which is an injection section insertion section in which the lubrication line 130A (the cylindrical section on the side of the base end section) is pressed in, a fourth semi-cylindrical section 176 and a fifth semi-cylindrical section 177, each of which is an imaging unit insertion section in which the endoscope 160A (the cylindrical section on the side of the base end section) is pressed in, a second connecting section 178, which connects the third semi-cylindrical section 175 to the fourth semi-cylindrical section 176, and a third connecting section 179, which connects the third semi-cylindrical section 175 to the fifth semi-cylindrical section 177.

[0198] The second connecting section 178 is a flat section that connects a first end section of the third semi-cylindrical section 175 with a first end section of the fourth semi-cylindrical section 176. This flat section (the second connecting section 178) extends tangentially to the third semi-cylindrical section 175 and the fourth semi-cylindrical section 176 (see Fig. 28).

[0199] The third connecting section 179 is a flat section that connects a second end section of the third semi-cylindrical section 175 with a first end section of the fifth semi-cylindrical section 177. This flat section (the third connecting section 179) extends tangentially to the third semi-cylindrical section 175 and the fifth semi-cylindrical section 177 (see Fig. 28).

[0200] The fourth semi-cylindrical section 176 is formed from a first end section of the plate that is bent back into a semi-cylindrical shape. Similarly, the fifth semi-cylindrical section 177 comprises a second end section of the plate that is bent back into a semi-cylindrical shape.

[0201] The third semi-cylindrical section 175 is formed in a plate section between the fourth semi-cylindrical section 176 and the fifth semi-cylindrical section 177.

[0202] The second connecting section 178 is a plate section between the third semi-cylindrical section 175 and the fourth semi-cylindrical section 176. The third connecting section 179 is a plate section between the third semi-cylindrical section 175 and the fifth semi-cylindrical section 177.

[0203] An end section (a free end section) of the plate comprises a first pre-tensioning section 190, which pre-tensions the endoscope 160A (the cylindrical section on the side of the base end section) inserted into the fifth semi-cylindrical section 177 with respect to the fifth semi-cylindrical section 177, and a second pre-tensioning section 191, which pre-tensions the lubrication line 130A (the cylindrical section on the side of the base end section) inserted into the third semi-cylindrical section 175 with respect to the third semi-cylindrical section 175.

[0204] The third semi-cylindrical section 175 is attached to the lubrication line 130A (the cylindrical section on the side of the base end section), which is inserted into the third semi-cylindrical section 175. This attachment can be carried out using any known method, such as gluing or welding.

[0205] The retaining element 170A (the plate) is made of synthetic resin or spring steel. This means that the retaining element 170A can be formed by injection molding a short resin or by bending or pressing a plate-shaped piece of spring steel.

[0206] As described above, according to the first modification example, by pressing the endoscope 160A (the cylindrical section on the side of the base end section) into the fourth semi-cylindrical section 176 or the fifth semi-cylindrical section 177, depending on the internal structure of the coupling housing 30, the operator can position the endoscope 160A at a suitable angular position with respect to the lubrication line 130A. Consequently, when inserting the insertion section 180 (the lubrication line 130A and the endoscope 160A) into the corresponding section C, a collision of the insertion section 180 (the lubrication line 130A and the endoscope 160A) with obstructions in the coupling housing 30 can be avoided.

[0207] Furthermore, according to the first modification example, the second connecting section 178 and the third connecting section 179 are flat sections. Thus, compared with a second modification example described below, in which a fourth connecting section 178B and a fifth connecting section 179B, corresponding to the second connecting section 178 and the third connecting section 179 respectively, are curved sections, the manufacturing costs (the processing costs for bending the second connecting section 178 and the third connecting section 179, or the like) of the retaining element 170A can be reduced.

[0208] Furthermore, according to the first modification example, the same effect as in the fifth embodiment can be achieved by performing the same steps as in the first to the eighth steps described in the fifth embodiment.

[0209] The second modification example of the fifth embodiment is described below.

[0210] Fig. Figure 29 is a perspective view of a holding element 170B, which is the second modification example, and Fig. 30 is a cross-sectional view along line CC of Fig. 29.

[0211] The retaining element 170B corresponds to a retaining element in which the second connecting section 178, which is the flat section of the retaining element 170A as in the first modification example, is replaced by the fourth connecting section 178B, which is the curved section, and the third connecting section 179, which is the flat section of the retaining element 170A as in the first modification example, is replaced by the fifth connecting section 179B, which is the curved section. Furthermore, the third semi-cylindrical section 175 is not attached to the lubrication line 130A (the cylindrical section on the side of the base end section) that is inserted into the third semi-cylindrical section 175. Otherwise, it is the same as the retaining element 170A according to the first modification example.The differences compared to the retaining element 170A according to the first modification example are described below, and the same configurations are designated with the same reference symbols, and the description is omitted where necessary.

[0212] As it is in the Fig. 29 and Fig. As shown in Figure 30, the retaining element 170B comprises the third semi-cylindrical section 175, which is an injection section insertion section into which the lubrication line 130A (the cylindrical section on the side of the base end section) is pressed, the fourth semi-cylindrical section 176 and the fifth semi-cylindrical section 177, each of which is an imaging unit insertion section into which the endoscope 160A (the cylindrical section on the side of the base end section) is pressed, the fourth connecting section 178B, which connects the third semi-cylindrical section 175 to the fourth semi-cylindrical section 176, and the fifth connecting section 179B, which connects the third semi-cylindrical section 175 to the fifth semi-cylindrical section 177.

[0213] The fourth connecting section 178B is the curved section that connects a first end section of the third semi-cylindrical section 175 with a first end section of the fourth semi-cylindrical section 176.

[0214] The fifth connecting section 179B is the curved section that connects a second end section of the third semi-cylindrical section 175 with a first end section of the fifth semi-cylindrical section 177.

[0215] The fourth connecting section 178B is a plate section between the third semi-cylindrical section 175 and the fourth semi-cylindrical section 176. The fifth connecting section 179B is a plate section between the third semi-cylindrical section 175 and the fifth semi-cylindrical section 177.

[0216] The retaining element 170B (the plate) is made of synthetic resin or spring steel. This means that the retaining element 170B can be formed by injection molding a synthetic resin or by bending or pressing a plate-shaped piece of spring steel.

[0217] As described above, according to the second modification example, the operator can position the endoscope 160A at a suitable angular position relative to the lubrication line 130A by pressing the endoscope 160A (the cylindrical section on the side of the base end section) into the fourth semi-cylindrical section 176 or the fifth semi-cylindrical section 177, depending on the internal structure of the coupling housing 30. Consequently, when inserting the insertion section 180 (containing the lubrication line 130A and the endoscope 160A) into the corresponding section C, a collision of the insertion section 180 (containing the lubrication line 130A and the endoscope 160A) with obstructions inside the coupling housing 30 can be avoided.

[0218] Furthermore, according to the second modification example, by performing the same steps as the first to eighth steps described in the fifth embodiment, the same effect as in the fifth embodiment can be achieved.

[0219] The fifth embodiment described above illustrates the use of fat as a fluid substance. However, the present invention is not limited to this. For example, a fluid can be used as the fluid substance. In this case, the corresponding section C is the section to which the fluid must be supplied. Furthermore, a fluid substance other than fat and fluid can be used as the fluid substance.

[0220] Furthermore, the fifth embodiment describes an example in which the injection device and the insertion direction guidance method of the present invention are applied to the field of vehicles (grease injection maintenance of the clutch release mechanism). However, the present invention is not limited to this. For example, the injection device and the insertion direction guidance method of the present invention can be applied to various other fields besides vehicles, such as medicine or semiconductors. For example, the fifth embodiment described above describes an example in which the wall section between the operator and the corresponding section is the clutch housing 30. However, the present invention is not limited to this.This means that the wall section between the operator and the corresponding section can be a wall section corresponding to the area to which the injection device and the insertion direction guidance method of the present invention are applied. Furthermore, the fifth embodiment describes an example in which the insertion section 180 is inserted into the corresponding section C while (that is, while guiding the insertion direction of the insertion section 180 into the corresponding section) the insertion section 180 is held in contact with the corner section of the opening section (for example, the through-hole 31) formed in the wall section (for example, the coupling housing 30) between the operator and the corresponding section. However, the present invention is not limited to this.For example, if a notch section (not shown) is formed in the wall section between the operator and the corresponding section, the insertion section 180 can be inserted into the corresponding section C while ensuring that the insertion section 180 is in contact with the corner section of the notch section (that is, while the insertion direction of the insertion section 180 is guided into the corresponding section). Sixth embodiment

[0221] A sixth embodiment, a configuration example for removing foreign substances adhering to the corresponding section C, is described below. This configuration example can be applied to the first through fifth embodiments. Furthermore, this configuration example can be applied not only to removing foreign substances adhering to the corresponding section C, but also to removing foreign substances adhering to the surrounding area of ​​the corresponding section C or the like.

[0222] The Fig. 31 and Fig. Figure 32 are perspective views of the configuration example for removing the foreign substances adhering to the corresponding section C.

[0223] As it is in Fig. As shown in Figure 31, the configuration example for removing the foreign substances adhering to the corresponding section C includes an insertion section 200 which is inserted into the corresponding section C in a confined space while being grasped by an operator.

[0224] The inlet section 200 comprises an injection section 201. The injection section 201 is a double pipe comprising an inner pipe 202 and an outer pipe 203. The inner pipe 202 is a pipe comprising, at its tip end section, a first fluid substance injection port 202a, from which grease (an example of the first fluid substance and the fluid substance for application of the present invention) supplied to the inner pipe 202 is injected. For example, the inner pipe 202 is the lubrication line 130 of the first to fourth embodiments and the lubrication line 130A of the fifth embodiment. A lubrication device 205 is connected to the inner pipe 202 via a flexible line 206. The lubrication device 205 is, for example, the lubrication device 150 of the first to fifth embodiments.The grease supplied by the lubrication device 205 via the flexible line 206 is fed via the inner pipe 202 to the first fluid substance injection port 202a and is injected from the first fluid substance injection port 202a. The grease injected from the first fluid substance injection port 202a is supplied (applied) to the corresponding section C.

[0225] The outer pipe 203 is a pipe that forms an annular pipe 204 between the outer pipe 203 (the inner circumferential area) and the inner pipe 202 (the outer circumferential area). That is, the space around the inner pipe 202 is defined as the annular pipe 204 by the outer pipe 203. Consequently, compared to the case described below, Fig. 34. Space can be saved. The annular pipe 204 can, for example, form a spacer (not shown) between the inner pipe 202 (the outer circumferential surface) and the outer pipe 203 (the inner circumferential surface). The spacer can, for example, be a convex section (or sections) formed by plastic deformation of a part of the outer pipe 203 (the inner circumferential surface), or it can be further spacers.

[0226] The inner pipe 202 and the outer pipe 203 can be a round pipe, a rectangular pipe or a pipe of another shape.

[0227] The annular pipeline 204 is a pipeline comprising, at its tip end section, a second fluid substance injection port 204a, from which air (an example of a second fluid substance and a fluid substance for removing foreign matter according to the present invention) introduced into the annular pipeline 204 is injected (blown in). An air source 207 is connected to the annular pipeline 204. For example, the air source 207 is, as shown in Fig. Figure 32 shows a flexible line 208 connected to a through-hole 203a formed on the side of the base end section of the outer pipe 203, and is connected to the annular pipe 204. The air source 207 is, for example, an electric air pump capable of switching between supplying and stopping air by an operator. The air supplied by the air source 207 via the flexible line 208 is fed via the annular pipe 204 to the second fluid substance injection port 204a and injected (blown in) from the second fluid substance injection port 204a. The air injected from the second fluid substance injection port 204a is blown towards the corresponding section C. As a result, foreign matter (for example, sludge, dust, powder) adhering to the corresponding section C is removed (cleaned).

[0228] Furthermore, the introductory section 200 includes an imaging unit 220. The imaging unit 220 is, for example, the endoscope 160 of the first to fourth embodiments and the endoscope 160A of the fifth embodiment. To prevent grease adhesion and the like, the imaging unit 220 can be arranged at a position separated from the tip end section (the first fluid substance injection port 202a, the second fluid substance injection port 204a) of the injection section 201 by a certain distance.

[0229] The following is a procedure for removing the foreign substances adhering to the corresponding section C.

[0230] First, as a first step, an operator inserts the insertion section 200 through the through-hole 31 of the coupling housing 30.

[0231] Each of the following steps is performed while paying close attention to the screen (an image containing the tip end section of the inner pipe 202, the tip end section of the annular pipe 204 and their surroundings (for example, foreign matter adhering to the corresponding section C)) displayed on the display section 163, which is attached to the actuating section 162, which is held by the operator with one hand (for example, the right hand).

[0232] Then, as a second step, the operator inserts the insertion section 200, grasped with the other hand (for example, the left hand), into the corresponding section C until the second fluid substance injection port 204a reaches the environment of the corresponding section C, to which the foreign substances adhere.

[0233] Then, as a third step, the operator activates the air source 207 to introduce (blow in) air from the second fluid substance injection port 204a and blow the air towards the corresponding section C. By performing the individual steps described above, the foreign substances adhering to the corresponding section C can be removed (cleaned) from that section. Furthermore, in the second step, while air is being introduced (blown in) from the second fluid substance injection port 204a, the insertion section 200 can be inserted into the corresponding section C, and in the step for supplying (introducing) grease to the corresponding section C, the air source 207 can be activated to stop the introduction (blowing in) of air from the second fluid substance injection port 204a.

[0234] As described above, according to the sixth embodiment, by blowing the air injected (blown) from the second fluid substance injection port 204a towards the corresponding section C, the foreign substances adhering to the corresponding section C in the narrow space can be removed (cleaned).

[0235] The following is a modification example.

[0236] Fig. Figure 33 is a perspective view of a configuration example (modification example 1) for removing foreign substances adhering to the corresponding section C.

[0237] As it is in Fig. As shown in Figure 33, the tip end section of the inner pipe 202 can protrude further than the tip end section of the outer pipe 203. In this way, it is possible to avoid the second fluid substance injection port 204a becoming clogged with grease.

[0238] Fig. Figure 34 is a perspective view of a configuration example (modification example 1) for removing foreign substances adhering to the corresponding section C.

[0239] In the sixth embodiment, an example is described in which the injection section, which is a double pipe comprising the inner pipe 202 and the outer pipe 203, is used as the injection section 201. However, the present invention is not limited to this.

[0240] For example, as it says in Fig. Figure 34 shows that the injection section 201 is an injection section comprising a first pipeline 210 and a second pipeline 211 arranged parallel to each other.

[0241] The first pipe 210 is a pipe that includes a first fluid substance injection port 210a at its tip end, from which grease supplied to the first pipe 210 is injected. The second pipe 211 is a pipe that includes a second fluid substance injection port 211a at its tip end, from which air supplied to the second pipe 211 is injected (blown).

[0242] The same effect as that of the sixth embodiment can be achieved through this modification example.

[0243] The sixth embodiment describes an example in which grease is used as the first fluid substance. However, the present invention is not limited to this. For example, a fluid can be used as the first fluid substance. In this case, the corresponding section C is a section to which the fluid must be supplied. Furthermore, a fluid substance other than grease and fluid can be used as the first fluid substance, for example, solder (e.g., molten solder). In this case, the corresponding section C is a section to which the solder must be supplied.

[0244] Furthermore, the sixth embodiment describes an example in which a gas, such as air (for example, air at room temperature), is used as the second fluid substance. However, the present invention is not limited to this. A liquid, such as a cleaning fluid, can be used as the second fluid substance. Furthermore, for example, if the corresponding section C is dried, air at a high temperature (warm air) can be used as the second fluid substance. Furthermore, if the corresponding section C is cooled, air at a low temperature (cold air) can be used as the second fluid substance.

[0245] Furthermore, the sixth embodiment describes an example in which the injection device of the present invention is applied to the field of vehicles (grease injection maintenance of the clutch release mechanism). However, the present invention is not limited to this. The injection device of the present invention can be applied to various other fields besides vehicles, such as medicine or semiconductors.

[0246] Furthermore, the sixth embodiment describes an example in which the introductory section 200 includes the imaging unit 220. However, the present invention is not limited to this. For example, the imaging unit 220 can be omitted.

[0247] All numerical values ​​shown in the above embodiments are examples, and it is understood that other suitable numerical values ​​may also be used.

[0248] Each of the above embodiments is merely an example in every respect. The present invention is not limited by the description of the above embodiments. The present invention can be implemented in various other forms without departing from its core or key features.
