Description

Technical Field

[0001] This invention relates to a retaining member, an injection device, and a method for guiding the insertion direction. Background Technology

[0002] An apparatus is proposed, which is configured to insert an insertion part (such as a grease supply tube) into a guide through hole of a guide clamp fixed to a clutch housing toward a corresponding part (the part where grease needs to be supplied from the top end of the grease supply tube) (for example, see Japanese Patent Application Laid-Open No. 2020-37949).

[0003] However, Japanese Patent Application Publication No. 2020-37949 has the following problem: it cannot be applied in cases where the guide clamp cannot be fixed to the clamp fixing object (e.g., clutch housing), for example, when the space for fixing the guide clamp cannot be guaranteed by the construction. Summary of the Invention

[0004] The present invention provides a retaining member, an ejection device, and an insertion direction guiding method for inserting an insertion part toward a corresponding part without using a guide clamp.

[0005] The retaining member of the first aspect of the present invention is configured to hold the ejection portion and the imaging portion in a state where the ejection portion of the insertion portion and the imaging portion are arranged side by side adjacently. The insertion portion is configured to be inserted into a corresponding portion in a narrow space while being held by an operator. The ejection portion is cylindrical in shape and has a fluid ejection port at its top end. The imaging portion is cylindrical in shape and is configured to capture an image including the top end of the ejection portion and the surrounding environment of the top end. The retaining member includes: an ejection portion insertion portion configured for pressing the ejection portion in; and an imaging portion insertion portion configured for pressing the imaging portion in.

[0006] With this configuration, the insertion part can be inserted into the corresponding part without the use of a guide clamp.

[0007] This is because the guiding function is achieved by retaining the component.

[0008] In the first embodiment described above, the retaining member may also include a first connecting portion configured to connect the ejection portion insertion portion to the imaging portion insertion portion. Alternatively, the ejection portion insertion portion may be a first semi-cylindrical portion configured for the ejection portion to be pressed in, and the imaging portion insertion portion may be a second semi-cylindrical portion configured for the imaging portion to be pressed in.

[0009] In the first embodiment described above, the first connecting portion may also be a flat portion configured to connect one end of the first semi-cylindrical portion to one end of the second semi-cylindrical portion.

[0010] In the first embodiment described above, the first semi-cylindrical portion may be a section where one end of the plate is folded back into a semi-cylindrical shape. Alternatively, the second semi-cylindrical portion may be a section where the other end of the plate is folded back into a semi-cylindrical shape. Alternatively, the first connecting portion may be a plate portion between the first and second semi-cylindrical portions.

[0011] In the first embodiment described above, the retaining member may also include a second connecting portion and a third connecting portion. Alternatively, the injection insertion portion may be a third semi-cylindrical portion configured for pressing the injection portion into. Alternatively, the imaging insertion portion may include a fourth semi-cylindrical portion configured for pressing the imaging portion into, and a fifth semi-cylindrical portion configured for pressing the imaging portion into. Alternatively, the second connecting portion may be configured to connect the third semi-cylindrical portion to the fourth semi-cylindrical portion, and the third connecting portion may be configured to connect the third semi-cylindrical portion to the fifth semi-cylindrical portion.

[0012] In the first embodiment described above, the second connecting portion may be a flat portion configured to connect one end of the third semi-cylindrical portion to one end of the fourth semi-cylindrical portion, and the third connecting portion may be a flat portion configured to connect the other end of the third semi-cylindrical portion to one end of the fifth semi-cylindrical portion.

[0013] In the first embodiment described above, the third semi-cylindrical portion may also be fixed to the ejection portion inserted into the third semi-cylindrical portion.

[0014] In the first embodiment described above, the fourth semi-cylindrical portion may be a portion where one end of the plate is folded back into a semi-cylindrical shape. Alternatively, the fifth semi-cylindrical portion may be a portion where the other end of the plate is folded back into a semi-cylindrical shape. Alternatively, the third semi-cylindrical portion may be a plate portion between the fourth and fifth semi-cylindrical portions. Alternatively, the second connecting portion may be a plate portion between the third and fourth semi-cylindrical portions, and the third connecting portion may be a plate portion between the third and fifth semi-cylindrical portions. Alternatively, one end of the plate may include: a first force-applying portion configured to apply force to the fifth semi-cylindrical portion by the shooting portion inserted into it; and a second force-applying portion configured to apply force to the third semi-cylindrical portion by the ejection portion inserted into it.

[0015] In the first embodiment described above, the plate may also be made of synthetic resin or spring steel.

[0016] The second aspect of the present invention provides an ejection device comprising an insertion portion configured to be inserted into a corresponding portion within a confined space while held by an operator. The insertion portion includes: a cylindrical ejection portion having a fluid ejection port at its top end; a cylindrical imaging portion configured to capture an image including the top end of the ejection portion and its surrounding environment; and a holding member configured to hold the ejection portion and the imaging portion in a side-by-side arrangement, the holding member including an ejection portion insertion portion and an imaging portion insertion portion. The ejection portion insertion portion is configured for pressing the ejection portion in. The imaging portion insertion portion is configured for pressing the imaging portion in. An ejection portion side mark is provided on the ejection portion. By rotating the holding member, which holds the ejection portion and the imaging portion, relative to the ejection portion, and aligning the holding member side mark of the holding member with the ejection portion side mark, the imaging portion is positioned at a predetermined angular position relative to the ejection portion.

[0017] With this configuration, the insertion part can be inserted into the corresponding part without the use of a guide clamp.

[0018] This is because the guiding function is achieved by retaining the component.

[0019] Furthermore, this configuration allows the imaging unit to be positioned at an appropriate angle relative to the emission unit.

[0020] This is because a retaining member is provided to hold the ejection section and the imaging section in a state where the ejection section and the imaging section are arranged side by side and adjacent to each other, and an ejection section side mark (e.g., a scribing line) is provided on the ejection section, so that the retaining member side mark (e.g., the winding end of the retaining member) of the retaining member is consistent with the ejection section side mark (e.g., the scribing line).

[0021] In the second embodiment described above, the retaining member side mark may also be the winding end of the retaining member.

[0022] A third aspect of the present invention is an insertion direction guiding method for guiding the insertion direction of an insert. The insert is configured to be inserted toward a corresponding part in a confined space while held by an operator. The insert includes an ejection part and an imaging part. The ejection part is cylindrical in shape and has a fluid ejection port at its top end. The imaging part is cylindrical in shape and configured to capture an image including the top end of the ejection part and the surrounding environment of the top end. The insert is held by a holding member with the ejection part and the imaging part arranged side-by-side adjacent to each other. The insertion direction guiding method includes: inserting the insert into an opening or cut in a partition wall provided between the operator and the corresponding part; and inserting the insert toward the corresponding part while bringing the holding member of the insert inserted into the opening or cut into contact with at least a corner of the opening or cut.

[0023] Through the various solutions of the present invention, it is possible to provide a retaining member, an ejection device, and an insertion direction guiding method that can insert the insertion part toward the corresponding part without using a guide clamp. Attached Figure Description

[0053] Before describing the embodiments below, the ejection device (hereinafter also referred to as the grease supply device) of the clutch disengagement mechanism will be specifically described as a reference example. It should be noted that the present invention is not limited to the embodiments described below.

[0054] Reference Example

[0055] The grease supply device in the reference example is used to perform inspection and grease injection maintenance in a low cost and short time for poor sliding caused by grease leakage from the grease lubrication part of the shift fork in the MT (Manual Transmission) clutch housing and foreign matter contamination after the manual transmission vehicle has been submerged in water / crossed a river. This is due to grease leakage from the grease lubrication part of the shift fork in the MT clutch housing and foreign matter contamination.

[0056] Figure 1 This is a schematic diagram illustrating the clutch disengagement mechanism of a reference example. (e.g.) Figure 1 As shown, the clutch device 1 is configured to include: a clutch body 10 for connecting / disconnecting power; a clutch disengagement mechanism 20 for operating the clutch body 10; and a clutch housing 30 that internally houses the clutch body 10. For example, the clutch device 1 is mounted on a manual transmission vehicle and is positioned between the engine and the transmission.

[0057] It should be noted that, Figure 1The X direction, as shown, represents the axial direction along the central axis, and the Z direction represents the direction orthogonal to the central axis (sometimes referred to as the radial or height direction). When the Z direction is set as the height direction, the upper side is sometimes referred to as the top end side, and the lower side as the base end side. Furthermore, the Y direction, described later, represents the direction orthogonal to both the X and Z directions. Sometimes the Y direction is referred to as the width direction.

[0058] The clutch body 10 includes a clutch disc 11, a clutch cover 12, a pressure plate 13, a diaphragm spring 14, and a release bearing 15.

[0059] The clutch disc 11 has a friction surface (clutchfacing) that is sandwiched between the pressure plate 13 and the flywheel 16, and it engages with the input shaft 3 of the transmission via splines. The friction between the friction surface of the clutch disc 11 and the flywheel 16 transmits the rotation of the flywheel 16 to the input shaft 3. The flywheel 16 is bolted to the crankshaft 2 of the engine, and the flywheel 16 rotates integrally with the crankshaft 2.

[0060] The clutch cover 12 is configured to cover the outer periphery of the clutch disc 11 and rotates integrally 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 a component used to press the friction surface of the clutch disc 11 toward the flywheel 16 via the pressure plate 13, and is located on the opposite side of the friction surface of the clutch disc 11 relative to the pressure plate 13. The periphery of the diaphragm spring 14 is connected to the pressure plate 13, and the central portion of the diaphragm spring 14 is connected to the release bearing 15. Thus, the diaphragm spring 14 can press against the pressure plate 13.

[0061] When the clutch body 10 is engaged, the pressure plate 13 uses the elastic force of the diaphragm spring 14 to press the friction surface of the clutch disc 11 toward the flywheel 16. This generates friction between the friction surface of the clutch disc 11 and the flywheel 16, thus transmitting the rotation of the flywheel 16 to the clutch disc 11 in the engaged state.

[0062] When the clutch body 10 is disengaged, the release bearing 15 pushes the center of the diaphragm spring 14, thereby displacing the periphery of the diaphragm spring 14 away from the flywheel 16. At this time, the pressure plate 13 and the diaphragm spring 14 are pulled closer together away from the flywheel 16. As a result, the friction between the friction surface of the clutch disc 11 and the flywheel 16 is eliminated, thus achieving the disengaged state where the rotation of the flywheel 16 is not transmitted to the clutch disc 11.

[0063] The clutch disengagement mechanism 20 includes a clutch disengagement fork 21, a disengagement fork support 22, and a release cylinder 23.

[0064] The clutch release fork 21 is a component for axially moving the release bearing 15 and is configured to swing while supported by the release fork support 22. The clutch release fork 21 is an elongated metal component with a configuration where the top side is divided into two strands.

[0065] like Figure 1 As shown, one end of the clutch release fork 21 is formed by a pressing portion 21a that presses the release bearing 15 axially. The pressing portion 21a is configured with a two-pronged structure, with its top end divided into two branches, thereby clamping the input shaft 3 inside the clutch housing 30. The portion of the pressing portion 21a that faces the release bearing 15 axially (the abutting portion) contacts the release bearing 15. The other end of the clutch release fork 21 is formed by a connecting portion 21b, which protrudes outward from the clutch housing 30 via a through hole 31 and is connected to the release cylinder 23. Furthermore, the other end of the clutch release fork 21 is covered by a fork boot 32 at the position where it extends outward from the clutch housing 30. The fork boot 32 is fitted into the through hole 31. A hole (cooling hole) may also be provided in the fork boot 32 for releasing the frictional heat generated when the clutch body 10 is in a semi-engaged state to the outside of the clutch housing 30.

[0066] Furthermore, the clutch release fork 21 has a fulcrum portion 21c supported by the release fork support member 22 between the pressing portion 21a and the connecting portion 21b. The release fork support member 22 consists of a main body portion fixed to the partition wall of the clutch housing 30 and a pivot portion (not shown) with a spherical surface at the top end of the main body portion. The partition wall of the clutch housing 30 consists of a retainer fitted with a bearing (not shown) that supports the input shaft 3. The retainer is a component fixed to the clutch housing 30. The root side of the release fork support member 22 is bolted to the retainer. In addition, inside the clutch housing 30, the boss portion 30a of the retainer extends along the input shaft 3. The input shaft 3 is inserted through the inside of the boss portion 30a.

[0067] The release bearing 15 is configured to move axially relative to the boss 30a while being supported on the outer periphery of the boss 30a via a sleeve. The release bearing 15 is configured to contact the central portion of the diaphragm spring 14. The release bearing 15 has: an outer ring supported on the boss 30a by a sleeve; and an inner ring that contacts the central portion of the diaphragm spring 14. In the release bearing 15, the inner ring that contacts the diaphragm spring 14 rotates, while the outer ring that contacts the clutch release fork 21 does not rotate.

[0068] Furthermore, when the driver depresses the clutch pedal (not shown), the release cylinder 23 operates. When the connecting part 21b is operated by the release cylinder 23, the clutch release fork 21 swings around the fulcrum part 21c. Through this swinging, the pressing part 21a presses the release bearing 15, causing the release bearing 15 to move axially and push the central part of the diaphragm spring 14 towards the flywheel 16, thereby disengaging the clutch body 10. When the clutch body 10 is disengaged, the flywheel 16 and the clutch disc 11 are disconnected, preventing power transmission. When the operating force from the release cylinder 23 is released, the pressing force from the pressing part 21a on the release bearing 15 disappears, thereby engaging the clutch body 10. When the clutch body 10 is engaged, the flywheel 16 and the clutch disc 11 are connected, enabling power transmission. Thus, the connection and disconnection of the power transmission path between the crankshaft 2 on the engine side and the input shaft 3 on the transmission side are achieved through the swinging of the clutch release fork 21.

[0069] Next, the grease supply device of the reference example will be described. The grease supply device 100 is a device that supplies grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15. The grease supply device 100 is configured such that: the second clamp 120 (insertion part 121) is inserted into the guide through hole (first hole 113, second hole 114) of the first clamp 110, which is fixed to the clutch housing 30 as described later, and the second clamp 120 (insertion part 121) is inserted toward the corresponding part C until the top end 131 of the grease supply pipe 130 provided in the second clamp 120 and the corresponding part C are in a predetermined positional relationship. Figure 1 As shown, corresponding part C refers to the contact portion between the clutch release fork 21 (pressing part 21a), which is a grease-requiring part (the part that needs to be supplied with lubricating grease from the top end 131 of the grease supply pipe 130), and the release bearing 15. Figure 1 As shown, the corresponding part C is disposed in the internal space surrounded by the clutch housing 30 (an example of the cover member of the present invention). A through hole (through hole 31) for clamp fixing is formed in the clutch housing 30, which communicates with the internal space.

[0070] When a vehicle equipped with the clutch device 1 is used in an environment containing sand, mud, or other pollutants, foreign objects may sometimes enter the clutch housing 30 through the cooling holes of the shift fork sleeve 32, the cooling holes provided in the clutch housing 30, or the drainage openings (none shown). Therefore, it is desirable to maintain the clutch disengagement mechanism 20 and perform grease supply maintenance by adding grease to the contact portion between the clutch disengagement fork 21 and the release bearing 15. Therefore, the grease supply device 100 is configured to perform grease supply maintenance without removing the clutch housing 30 (or the manual transmission unit including the clutch housing 30) from the vehicle. This grease supply device 100 uses a grease supply pipe 130 (in... Figure 2 (As shown in the figure) Grease is supplied from the outside of the clutch housing 30 to the contact portion between the clutch release fork 21 and the release bearing 15, which is the part requiring grease supply, through the through hole 31 of the clutch housing 30.

[0071] like Figure 2 As shown, the grease supply device 100 is configured to include a first clamp 110, a second clamp 120, a grease supply pipe 130, a flexible pipe 140, and a grease dispenser 150. The first clamp 110 and the second clamp 120 are components used to position the grease supply pipe 130. The first clamp 110 is a component fitted into the through hole 31 of the clutch housing 30. The second clamp 120 is a component inserted into the insertion hole of the first clamp 110.

[0072] The first clamp 110 is a guide clamp that restricts the direction (insertion direction) of the grease supply tube 130 (grease injection tube), and has a base 111, a protrusion 112, and a first hole 113 and a second hole 114 for positioning. The first clamp 110 is a one-piece molded metal product. The base 111 is formed into a flat plate shape, having a shape that partially covers the opening of the through hole 31. The width of the base 111 (the length in the Y direction described later) is greater than the opening width of the through hole 31. The protrusion 112 is the portion that protrudes from the base 111 and is inserted into the through hole 31. The protrusion 112 functions as a positioning portion, which positions the first clamp 110 by abutting against the inner surface 31a of the through hole 31 and against the plane 21d of the clutch release fork 21.

[0073] The first hole 113 and the second hole 114 are insertion holes for inserting the grease supply tube 130 and the insertion portion 121 of the second clamp 120, and positioning holes for positioning the grease supply tube 130. The first hole 113 and the second hole 114 are arranged in the width direction of the first clamp 110, and are both through holes that extend from the base 111 on the base end side to the protrusion 112 on the top end side. It should be noted that in this description, without specifically distinguishing between the first hole 113 and the second hole 114, the first hole 113 and the second hole 114 are referred to as "insertion holes".

[0074] The second clamp 120 has a prism-shaped insertion portion 121, which is inserted into the first hole 113 and the second hole 114 of the first clamp 110; and a stop portion 122, which abuts against the surface 111a of the first clamp 110. The second clamp 120 is a one-piece metal product. Furthermore, the grease supply tube 130 is integrally formed into the second clamp 120. The second clamp 120 has two through holes 123 and 124 extending linearly from the base end side to the top end side along the insertion portion 121. One through hole 123 is for the grease supply tube. The other through hole 124 is for the endoscope. The grease supply tube 130 is fixed in the through hole 123 when inserted through it. The endoscope 160 is fixed in the through hole 124 when inserted through it (see reference). Figure 3 Furthermore, the stop portion 122 has a stop surface 122a that abuts against the surface 111a of the first clamp 110 (in Figure 3 (as shown in the image).

[0075] The grease supply pipe 130 is a pipe used to supply grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15 inside the clutch housing 30. The grease supply pipe 130 is an elongated ejection portion including a tip portion 131 for ejecting grease (an example of the fluid of the present invention). The grease supply pipe 130 is made of metal. An opening 131a (hereinafter also referred to as ejection port 131a) for ejecting grease is provided at the tip portion 131 of the grease supply pipe 130. A flexible tube 140 is connected to the base end side of the grease supply pipe 130. The grease supply pipe 130 is connected to the grease dispenser 150 via the flexible tube 140.

[0076] like Figure 3 As shown, the grease supply device 100 includes an endoscope 160 as an imaging unit. The endoscope 160 is an elongated imaging device with an imaging section at its tip 160a, which captures images of the tip 131 of the grease supply tube 130 and its surrounding environment (e.g., corresponding part C). The endoscope 160 is integrated into the second clamp 120 and protrudes from the tip side of the insertion portion 121. The tip side of the endoscope 160 is the portion inserted into the interior of the clutch housing 30, and a lens is provided at this tip 160a. The base side of the endoscope 160 is connected to the operation unit 162 via a cable 161. By operating the operation unit 162, an image of the internal structure of the clutch housing 30 can be captured by the endoscope 160. The images captured by the endoscope 160 (e.g., images of the tip 131 of the grease supply tube 130 and its surrounding environment (e.g., corresponding part C)) can be displayed on a display unit 163 mounted on the operation unit 162.

[0077] The grease supply unit 150 consists of a cylinder 151 and a push rod 152 (piston) (see reference). Figure 3The flexible tube 140 is connected to the cylinder 151 of the grease supply unit 150. By pushing the push rod 152 while the cylinder 151 is filled with grease, grease can be supplied from the grease supply unit 150 to the grease supply tube 130. For example, the grease supply tube 130 can be inserted into the clutch housing 30 through the through hole 31 while the grease supply tube 130 and the flexible tube 140 are pre-filled with grease, thereby smoothly performing grease supply achieved by operating the grease supply unit 150.

[0078] The tip 131 of the grease supply tube 130 has a tapered shape and includes an opening 131a for injecting grease. For example, as... Figure 4A As shown, the opening 131a of the grease supply tube 130 can be a circular opening 131a. Or, as... Figure 4B As shown, the opening 131a can also be flat. The top end 131 of the grease supply pipe 130 has a narrowed diameter shape, allowing it to pass through the narrow space within the clutch housing 30 to supply grease to the parts that need grease.

[0079] Here, refer to Figure 5 , Figures 6A-6C The first fixture 110 is described in detail. Figure 5 This is a top view of the base end side of the first clamp 110. Figure 6A It means Figure 5 The diagram showing the view from direction A. Figure 6B This is a three-dimensional view of the first clamp 110 as seen from the back side. Figure 6C It means Figure 5 A diagram of the VIC-VIC line cross section.

[0080] like Figure 5 As shown, the first clamp 110 has a rectangular opening with a first hole 113 and a second hole 114 on the surface 111a side of the base 111. The inner surface of the first hole 113 functions as a guide surface for positioning the grease supply tube 130 by abutting against the insertion part 121, and 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 opposite each other in the Y direction, forming the shorter side portion of the rectangle. The third surface 113c and the fourth surface 113d are opposite each other in the X direction, forming the longer side portion of the rectangle. The inner surface of the second hole 114 functions as a guide surface for positioning the grease supply tube 130, and has a first surface 114a, a second surface 114b, a third surface 114c, and a fourth surface 114d. The first face 114a and the second face 114b are opposite faces in the Y direction, forming the shorter side of a rectangle. The third face 114c and the fourth face 114d are opposite faces in the X direction, forming the longer side of a rectangle.

[0081] Furthermore, the first clamp 110 has an abutment surface 115 that abuts against the plane 21d of the clutch release fork 21. The abutment surface 115 is a positioning surface, and its position in the X direction can be determined by abutting against the plane 21d of the clutch release fork 21. Figure 6A As shown, the contact surface 115 has a predetermined width in the width direction (Y direction) of the base 111 and extends along the height direction (Z direction) of the protrusion 112.

[0082] like Figure 6B As shown, a key portion 116 is provided on the back side 111b of the first clamp 110. The key portion 116 is the part that hooks onto the clutch housing 30 when the protrusion 112 is inserted into the through hole 31. This key portion 116 functions as a part that holds the first clamp 110 within the through hole 31. Furthermore, the openings of the first hole 113 and the second hole 114, which open into the protrusion 112, are also rectangular in shape, similar to the base end side. Figure 6C As shown, the first hole 113 extends in a straight line inside the protrusion 112.

[0083] Next, refer to Figures 7-9 The method of grease supply implemented by the grease supply device 100 will be described. Figure 7 This diagram shows the state in which the first clamp 110 is assembled into the through hole 31 of the clutch housing 30. Figure 8 The diagram shows the state in which the grease supply pipe 130 extends toward the pressing part 21a of the clutch release fork 21 when the second clamp 120 is inserted into the insertion hole of the first clamp 110. Figure 9 This diagram illustrates the height position of the tip 131 of the grease supply tube 130. It should be noted that... Figure 9 The Z direction shown indicates the height direction. Before performing the following procedures, remove the shift fork cover 32. This opens the through hole 31 of the clutch housing 30 for inserting the grease supply pipe 130, etc. (see reference). Figure 2 , Figure 9 (etc.) are revealed.

[0084] As a first step, the first clamp 110 is fixed to the through hole 31 of the clutch housing 30.

[0085] Figure 10 It means from Figure 9 Diagram of the first clamp 110 and the second clamp 120 that have been extracted.

[0086] like Figure 10 As shown, the first clamp 110 is fixed to the clutch housing 30 (the portion surrounding the through hole 31) in a state where it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0087] Specifically, firstly, the protrusion 112 of the first clamp 110 is positioned opposite to the through hole 31 of the clutch housing 30 (see reference). Figure 2 And make the abutment surface 115 of the first clamp 110 and the clutch release fork 21 (plane 21d) face each other (in contact) (see reference). Figure 7 ).

[0088] Next, the first clamp 110 is moved along the clutch release fork 21 (plane 21d) towards the through hole 31 (refer to...). Figure 2 The arrow AR1 in the diagram slides and moves until the protrusion 112 of the first clamp 110 is inserted into the through hole 31 and the base 111 of the first clamp 110 abuts against the surrounding portion of the through hole 31 in the clutch housing 30.

[0089] The protrusion 112 of the first clamp 110 is inserted into the through hole 31. The sides 112a and 112b of the protrusion 112 are opposite (abut against) the inner surfaces 31a and 31b of the through hole 31, thereby positioning the first clamp 110 relative to the clutch housing 30 in the Y direction.

[0090] Furthermore, the base 111 of the first clamp 110 abuts against the periphery of the through hole 31 in the clutch housing 30, thereby positioning the first clamp 110 relative to the clutch housing 30 in the Z direction.

[0091] Next, the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, is moved along the direction of arrow AR2 (refer to...). Figure 7 , Figure 10 Push it in.

[0092] Specifically, the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, is positioned along the direction of arrow AR2 (refer to...). Figure 7 , Figure 10 Push in until the portion surrounding the through hole 31 in the clutch housing 30 is inserted (pressed in) into the space between the base 111 and the key 116 of the first clamp 110 (see reference). Figure 10 The through hole 31 extends to the bottom 117 between the base 111 and the key 116 of the first clamp 110, and the surrounding portion of the through hole 31 abuts against it.

[0093] The distance A1 between the base 111 and the key 116 of the first clamp 110 (refer to...) Figure 10 The thickness B1 of the portion surrounding the through hole 31 in the clutch housing 30 (refer to) Figure 10The relationship is set as A1 < B1. Therefore, when the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, is aligned along the direction of arrow AR2 (refer to...), Figure 7 , Figure 10 When pushed in, the portion surrounding the through hole 31 in the clutch housing 30 is inserted (pressed in) into the space between the base 111 and the key 116 of the first clamp 110. Thus, the first clamp 110 is fixed to the clutch housing 30.

[0094] Furthermore, the periphery of the through hole 31 in the clutch housing 30 abuts against the bottom 117 between the base 111 and the key 116 of the first clamp 110, thereby positioning the first clamp 110 relative to the clutch housing 30 in the X direction.

[0095] As described above, the first clamp 110 is fixed to the clutch housing 30 (the portion surrounding the through hole 31) in a state where it is positioned relative to the clutch housing 30 (an example of the fixing object of the present invention) in the X, Y, and Z directions. In other words, the first clamp 110 engages with the portion surrounding the through hole 31 in the clutch housing 30 in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions.

[0096] Thus, with the first clamp 110 fixed to the clutch housing 30 (the portion surrounding the through hole 31), the first hole 113 of the first clamp 110 extends toward the corresponding portion C (one of the pressing portions 21a) (see reference). Figure 9 Similarly, the second hole 114 of the first clamp 110 extends toward the corresponding part C (the pressing part 21a on the other side). It should be noted that the first clamp 110 can be removed from the clutch housing 30 by following the reverse steps described above.

[0097] The next step after the first step is the insertion process (insertion process) of inserting the grease supply pipe 130 and the second clamp 120 into the insertion holes (first hole 113, second hole 114) of the first clamp 110, which is fixed to the clutch housing 30 as described above. In this insertion process, the second clamp 120 is inserted into the insertion holes (first hole 113, second hole 114) of the first clamp 110 in two stages. On the sides 121a and 121b of the insertion portion 121 of the second clamp 120, at a predetermined distance from the top end, are markings as described later in the second embodiment. The outer periphery of the insertion portion 121 is formed into a rectangular shape. The sides 121a and 121b are the shorter sides of the rectangle. Furthermore, side 121a is one face in the Y direction, and side 121b is the other face in the Y direction. Furthermore, the rectangle of the insertion part 121 is smaller than the rectangle of the opening of the first hole 113 and the rectangle of the opening of the second hole 114.

[0098] like Figure 8 As shown, the insertion portion 121 of the second clamp 120 is inserted into the first hole 113 of the first clamp 110, thereby extending the grease supply pipe 130 toward the pressing portion 21a of the clutch release fork 21, which is the part requiring grease supply. The pressing portion 21a has a two-pronged structure, so the grease supply pipe 130 inserted into the first hole 113 extends toward one of the pressing portions 21a. Before the grease supply pipe 130 reaches the vicinity of the pressing portion 21a of the clutch release fork 21, it is sometimes necessary to avoid obstacles inside the clutch housing 30. For example, a clip, which is a component of the release bearing 15, can be listed as an obstacle. The clip is located near the two-pronged structure of the clutch release fork 21, so it is ideal that the grease supply pipe 130 does not come into contact with the clip before reaching the pressing portion 21a.

[0099] Therefore, as the second step (the first half of the insertion step), the insertion part 121 of the second clamp 120 is inserted into the insertion hole of the first clamp 110 until the marked position. In this second insertion state, the second clamp 120 can be moved relative to the first clamp 110 within the insertion hole, allowing the grease supply tube 130 and endoscope 160 to avoid obstacles within the clutch housing 30. That is, as the third step, a step is performed to move the second clamp 120 in a way that avoids the internal structure of the clutch housing 30 (avoidance action step). In the following steps, the operator performs the following operation: while looking at the screen displayed on the display 163 of the operation unit 162 held by one hand (e.g., the right hand) (including an image of the top part 131 of the grease supply tube 130 and its surrounding environment (e.g., the corresponding part C)), the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) is moved toward the corresponding part C in the direction of arrow AR3 (see reference). Figure 9 Insert the tube 130 so that the tip 131 of the grease supply tube 130 reaches the corresponding part C (refer to...). Figure 9 ).

[0100] Regarding the third step, when the insertion part 121 is inserted into the first hole 113, a gap (approximately 0.5 mm) is provided between the sides 121a and 121b of the insertion part 121 and the inner surface (inner wall) of the first hole 113. Similarly, when the insertion part 121 is inserted into the second hole 114, a gap (approximately 0.5 mm) is provided between the sides 121a and 121b of the insertion part 121 and the inner surface (inner wall) of the second hole 114. Therefore, as long as the second clamp 120 is inserted into the insertion hole up to the marked position, the grease supply tube 130 can be positioned at a height where it does not contact the clamping member of the release bearing 15 and avoids the position of the clamping member and other internal structures. In this case, the stop part 122 side can be held by hand, and the top end side of the insertion part 121 can be moved by swaying in the Y direction.

[0101] like Figure 9 As shown, the height of the tip 131 of the grease supply tube 130 at height h1 is such that it avoids the clamping member of the release bearing 15. In this case, the insertion of the grease supply tube 130 is stopped, and the position of the tip 131 is controlled in such a way that it avoids the clamping member of the release bearing 15. This height h1 also represents the insertion amount (stroke amount).

[0102] For example, in the third step, as a process of moving the grease supply pipe 130 away from obstacles within the clutch housing 30 from a state where the side surface 121b of the insertion portion 121 contacts the first surface 113a of the first hole 113, the side surface 121a of the insertion portion 121 contacts the second surface 113b of the first hole 113, which is in a non-contact state. At this time, the second clamp 120 is moved until the insertion portion 121 slides on the third surface 113c of the first hole 113, so that the side surface 121a contacts the second surface 113b. This sliding includes a parallel movement in the Y direction and a swaying motion that causes the tip portion 131 to sway left and right. Thus, the grease supply pipe 130 is positioned where it does not contact the clamping member.

[0103] Thus, after the position of the grease supply pipe 130 is determined to avoid obstacles within the clutch housing 30, the tip 131 of the grease supply pipe 130 is again brought closer to the area requiring grease supply. That is, the insertion process of the second clamp 120 is restarted, and the insertion part 121 is inserted into the through hole 31 until the stop part 122 of the second clamp 120 abuts against the base 111 of the first clamp 110. With the stop part 122 of the second clamp 120 in contact with the first clamp 110, the tip 131 of the grease supply pipe 130 is inserted into the clutch housing 30 to the predetermined target position. In other words, as the fourth process (the second half of the insertion process), the insertion part 121 is inserted deeper than the marked position, and the tip 131 of the grease supply pipe 130 is inserted into the area requiring grease supply.

[0104] like Figure 9 As shown, in the fourth step, the tip 131 of the grease supply pipe 130 reaches a height h2 where the pressing part 21a of one of the two-strand structures is located. Thus, the tip 131 of the grease supply pipe 130 can be positioned near the pressing part 21a of the clutch release fork 21. This height h2 becomes an insertion amount greater than the height h1.

[0105] Then, as the fifth step, the process of supplying grease from the opening 131a of the grease supply tube 130 is performed. In this fifth step, the operator, while looking at the screen displayed on the display unit 163 of the operation unit 162 which is held by one hand (e.g., the right hand) (including an image of the top part 131 of the grease supply tube 130 and its surrounding environment (e.g., the corresponding part C)), operates the grease supply device 150 by holding it with the other hand (e.g., the left hand). Figure 3 The push rod 152 shown is pushed axially, thereby supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C (see reference). Figure 9In the fifth step, when an appropriate amount of grease is supplied from the grease dispenser 150 connected to the grease supply tube 130, an appropriate amount of grease is ejected from the tip 131 of the grease supply tube 130, and the grease is applied to the pressing part 21a. In this case, the grease supply tube 130 is pre-filled with grease from the grease dispenser 150. Therefore, when the tip 131 of the grease supply tube 130 is positioned as desired, grease supply achieved by operating the grease dispenser 150 will proceed smoothly.

[0106] Then, when the grease supply in the fifth step is completed, the sixth step is to remove the grease supply tube 130. In the sixth step, while keeping the first clamp 110 fitted into the through hole 31, the grease at the tip 131 of the grease supply tube 130 is cut off. After that, the second clamp 120 is pulled out of the through hole 31, and the tip 131 of the grease supply tube 130 is also pulled out of the through hole 31 to the outside of the clutch housing 30.

[0107] For example, the second clamp 120 is pulled out of the insertion hole of the first clamp 110. When the second clamp 120 is pulled out of the insertion hole of the first clamp 110, the second clamp 120 can be moved left and right through the gap between the insertion hole and the insertion part 121. This prevents grease from adhering to parts and components other than the parts that need grease supply.

[0108] If the first to fifth processes described above are for the first hole 113, while maintaining the assembly state of the first fixture 110, the second to fifth processes are performed for the second hole 114. This allows grease to be supplied to both sides of the pressing part 21a with the two-strand structure.

[0109] It should be noted that if there are no obstructions inside the clutch housing 30 before reaching the lubrication point, the second and third steps described above can be omitted. In this case, the marking of the second clamp 120 may not be necessary, and the first step can proceed to the fourth step, inserting the insertion part 121 of the second clamp 120 into the insertion hole of the first clamp 110 and continuing to insert until the stop part 122 abuts against the first clamp 110.

[0110] As explained above, according to the grease supply device 100 of the reference example, grease can be supplied to the pressing portion 21a of the clutch release fork 21 even without removing the clutch housing 30 (or the manual transmission unit including the clutch housing 30) from the vehicle. As a result, grease supply maintenance work becomes easier and workability is improved.

[0111] First Implementation Method

[0112] Next, the injection device of the first embodiment will be described.

[0113] Figure 11 This is a schematic diagram of the ejection device 100A.

[0114] The ejection device 100A of the first embodiment differs from the above-described reference example mainly in that it does not have the first clamp 110 and the second clamp 120, and it has the holding member 170. Hereinafter, the description will focus on the differences from the above-described reference example, and the same reference numerals will be used for the same components as in the above-described reference example, and the description will be omitted as appropriate.

[0115] The ejection device 100A of the first embodiment, like the aforementioned reference example, includes an insertion part 180 (see reference 180) that is inserted into a corresponding part C in a confined space while being held by an operator. Figure 11 The insertion part 180 includes a grease supply tube 130A, an endoscope 160A, and a retaining member 170. Hereinafter, similar to the above-described reference example, the case between the clutch release fork 21 (pressing part 21a) and the release bearing 15, where a narrow space is required for grease supply (the portion requiring grease to be supplied from the tip 131 of the grease supply tube 130A), will be described as an example. It should be noted that one end of the clutch release fork 21 is formed by a pressing part 21a that presses the release bearing 15 axially (see reference). Figure 17 The pressing part 21a is configured with a two-strand structure on its top side, thereby clamping the input shaft 3 inside the clutch housing 30. It should be noted that... Figure 17 The diagram shows the corresponding part C on the near-front side, while the corresponding part C on the far side is located behind the release bearing 15 and is therefore not shown.

[0116] The grease supply tube 130A, like the grease supply tube 130 in the above-described reference example, is an elongated ejection portion including a tip portion 131 for ejecting lubricating grease (an example of the fluid of the present invention). This grease supply tube 130A is made of metal. To facilitate insertion of the tip portion 131 of the grease supply tube 130A between the clutch release fork 21 (pressing portion 21a), which is the point requiring grease supply, and the release bearing 15, the tip portion 131 of the grease supply tube 130A is designed as a prism shape with a rectangular cross-section of transverse length (see reference). Figure 11 The grease supply tube 130A, except for its tip 131, is cylindrical. It should be noted that the grease supply tube 130A, including its tip 131, can also be cylindrical.

[0117] Sometimes the layout of the internal structure of the clutch housing 30 differs for each vehicle model (or each manual transmission unit). Depending on the layout of the internal structure of the clutch housing 30, sometimes the path for inserting the insertion part 180 (grease supply tube 130A and endoscope 160A) from the through hole 31 of the clutch housing 30 toward the corresponding part C is straight, and sometimes the insertion path includes one or more bends along the way.

[0118] In the latter case, when the grease supply tube 130A extends in a straight line as in the grease supply tube 130 of the above-described reference example, the insertion part 180 (grease supply tube 130A and endoscope 160A) will interfere with the obstacles inside the clutch housing 30, making it difficult to insert the insertion part 180 (grease supply tube 130A and endoscope 160A) toward the corresponding part C.

[0119] Therefore, in the first embodiment, assuming that the path for inserting the insertion portion 180 (liposuction tube 130A and endoscope 160A) includes a bend, the portion C1 between the base end and the tip end 131 is bent. Thus, even if there is a bend in the path for inserting the insertion portion 180 (liposuction tube 130A and endoscope 160A), the insertion portion 180 (liposuction tube 130A and endoscope 160A) can be inserted towards the corresponding portion C more easily. It should be noted that, depending on the path for inserting the insertion portion 180 (liposuction tube 130A and endoscope 160A), sometimes multiple portions between the base end and the tip end 131 of the liposuction tube 130A may be bent.

[0120] The grease supply tube 130A has an injection port 131a at its top end 131 (top surface) for injecting grease supplied through a cylindrical tube portion. A flexible tube 140 is connected to the base end of the grease supply tube 130A. The grease supply tube 130A is connected to the grease dispenser 150 via the flexible tube 140.

[0121] Endoscope 160A is an elongated imaging device including an imaging section at its tip 160a, which captures images of the tip 131 of the liposuction tube 130A and its surrounding environment (e.g., corresponding section C). Endoscope 160A is a cylindrical shape with a diameter larger than that of the liposuction tube 130A, and the portion C2 between its base and tip 160a is bent at the same angle as the liposuction tube 130A. It should be noted that, similar to the liposuction tube 130A, depending on the path through which the insertion portion 180 (liposuction tube 130A and endoscope 160A) is inserted, sometimes multiple portions between the base and tip 160a of endoscope 160A are bent.

[0122] The base of the endoscope 160A is connected to the operating unit 162 via a cable 161. By operating the operating unit 162, an image of the internal structure of the clutch housing 30 can be captured by the endoscope 160A. The image captured by the endoscope 160A (e.g., an image including the tip 131 of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C)) can be displayed on the display unit 163 mounted on the operating unit 162.

[0123] Next, the retaining member 170 will be described.

[0124] like Figure 11 As shown, the retaining member 170 holds the liposuction tube 130A and the endoscope 160A in a state where the liposuction tube 130A and the endoscope 160A are arranged side by side and adjacent to each other.

[0125] Figure 12 yes Figure 11 Sectional view XII-XII, Figure 13 It is a three-dimensional view of component 170.

[0126] like Figure 12 , Figure 13 As shown, the retaining member 170 includes: an ejaculation insertion portion 171 for pressing in the grease supply tube 130A (the cylindrical portion on the base end side); an imaging insertion portion 172 for pressing in the endoscope 160A (the cylindrical portion on the base end side); and a first connecting portion 173 for connecting the ejaculation insertion portion 171 and the imaging insertion portion 172.

[0127] The injection insertion portion 171 is a first semi-cylindrical portion into which the grease supply tube 130A (the cylindrical portion on the base end side) is pressed. The imaging insertion portion 172 is a second semi-cylindrical portion into which the endoscope 160A (the cylindrical portion on the base end side) is pressed. The first connecting portion 173 is a flat portion that connects one end of the first semi-cylindrical portion (injection insertion portion 171) to one end of the second semi-cylindrical portion (imaging insertion portion 172). Hereinafter, the first connecting portion 173 will also be referred to as the flat portion 173. This flat portion (first connecting portion 173) extends along the tangential direction of the first semi-cylindrical portion (injection insertion portion 171) and the second semi-cylindrical portion (imaging insertion portion 172) (see reference). Figure 12 ).

[0128] The first semi-cylindrical portion (ejection insertion portion 171) is formed with one end of the plate folded back into a semi-cylindrical shape. Similarly, the second semi-cylindrical portion (shooting insertion portion 172) is formed with the other end of the plate folded back into a semi-cylindrical shape. The first connecting portion 173 is the plate portion between the first semi-cylindrical portion (ejection insertion portion 171) and the second semi-cylindrical portion (shooting insertion portion 172).

[0129] The retaining member 170 (plate) is made of synthetic resin or spring steel. That is, the retaining member 170 can be formed by injection molding of synthetic resin or by bending or pressure forming of plate-shaped spring steel.

[0130] Maintain the axial length L of component 170 (refer to) Figure 13 The length is set to be suitable for fixing the fat supply tube 130A and the endoscope 160A to each other (e.g., L = 40 mm).

[0131] The diameter of the injection insertion portion 171 is slightly larger than the diameter of the grease supply tube 130A. Therefore, when the grease supply tube 130A is inserted into the injection insertion portion 171, the injection insertion portion 171 undergoes elastic deformation and is fixed to the grease supply tube 130A (the cylindrical portion on the base end side) in a state of close contact with the outer peripheral surface of the grease supply tube 130A (the cylindrical portion on the base end side) by its restoring force.

[0132] Similarly, the diameter of the imaging insertion portion 172 is slightly larger than the diameter of the endoscope 160A. Therefore, when the endoscope 160A is inserted into the imaging insertion portion 172, the imaging insertion portion 172 undergoes elastic deformation and is fixed to the endoscope 160A (the cylindrical portion on the base end side) by its restoring force in a state of close contact with the outer peripheral surface of the endoscope 160A (the cylindrical portion on the base end side).

[0133] Figure 14 This is a perspective view of the grease supply tube 130A (the cylindrical part on the base end side).

[0134] like Figure 14 As shown, a first scribe line L1 and a second scribe line L2 extending axially are marked on the outer peripheral surface of the liposuction cannula 130A. The scribe lines L1 and L2 are used to position the endoscope 160A at an appropriate angle relative to the liposuction cannula 130A. This will be described later. The scribe lines L1 and L2 are an example of the ejection section side markings of the present invention. It should be noted that the ejection section side markings are not limited to the scribe lines L1 and L2, and may also be other markings such as lines drawn with a pen or sticker on the outer peripheral surface of the liposuction cannula 130A.

[0135] Next, refer to Figures 15-17 The method of grease supply implemented by the injection device 100A will be described. Figure 15 , Figure 16 This diagram shows the state in which the insertion part 180 is inserted into the through hole 31 of the clutch housing 30 to supply grease to the corresponding part C on the near-front side. It should be noted that... Figure 15 From and Figure 17 The diagram is obtained by observing the through hole 31 from the direction opposite to the middle arrow AR4. Figure 17The diagram shows the state in which the grease supply pipe 130A extends toward the corresponding part C on the near-forward side when the insertion part 180 is inserted into the through hole 31 of the clutch housing 30.

[0136] Before performing the following procedures, remove the shift fork cover 32. This will expose the through hole 31 (see reference 180) in the clutch housing 30 for inserting the insertion part 180. Figure 16 (etc.) are revealed.

[0137] The following is about the method. Figure 17 An example is given illustrating fat donation in the order of corresponding portion C on the proximal anterior side and corresponding portion C on the distal side. It should be noted that... Figure 17 In the middle, the corresponding part C on the far side is located behind the release bearing 15 and is therefore not shown.

[0138] First, as the first step, in order to avoid interference between the insertion part 180 (grease supply tube 130A and endoscope 160A) inserted towards the corresponding part C on the near front side and obstacles inside the clutch housing 30 (in addition, in order to ensure the field of view of the endoscope 160A), the operator positions the endoscope 160A at an appropriate angle relative to the grease supply tube 130A according to the layout of the internal structure of the clutch housing 30.

[0139] This is achieved by rotating the holding member 170, which holds the liposuction cannula 130A and the endoscope 160A, relative to the liposuction cannula 130A (see reference). Figure 15 Arrow AR5 in the middle), and make the winding end 174 on the injection insertion part 171 side of the retaining member 170 and the first scribe line L1 marked on the outer peripheral surface of the grease supply tube 130A (refer to Figure 14 Consistent (refer to) Figure 15 ).

[0140] The first line L1 is set at an angle θ1 relative to the fat supply canal 130A (reference line AX) on the endoscope 160A. Figure 15 In the case of the position, the winding end 174 on the injection insertion part 171 side is aligned with the first scribe line L1. Figure 15 In this case, the angle θ1 is, for example, 75°. The winding end 174 on the injection insertion portion 171 side is an example of the retaining member side marking of the present invention. It should be noted that the retaining member side marking is not limited to the winding end 174 on the injection insertion portion 171 side; it can also be other markings such as lines drawn with a pen or sticker on the retaining member 170. It should be noted that the reference line AX is, for example, along the upper surface of the prism-shaped top end 131 of the grease supply tube 130A (see reference). Figure 11 Extend in a parallel direction (refer to) Figure 11 ).

[0141] Therefore, the operator visually confirms the positional relationship between the winding end 174 of the insertion portion 171 side of the retaining member 170 and the first scribe line L1, thereby determining the position of the endoscope 160A relative to the liposuction tube 130A (reference line AX) at an angle θ1 (refer to...). Figure 15 The position of ).

[0142] Next, as a second step, the operator inserts the endoscope 160A into the insertion portion 180, positioned at the aforementioned angle θ1, via the through hole 31 of the clutch housing 30. The through hole 31 of the clutch housing 30 is an example of the "opening or cutout formed in the partition wall between the operator and the corresponding part" of the present invention. At this time, as... Figure 15 As shown, the corner of the retaining member 170, which is inserted into the shooting part 172, is aligned with the corresponding part C on the near-front side of the through hole 31 in the clutch housing 30. Figure 15 The insertion part 180 is inserted into the corresponding part C near the front while being guided in the insertion direction of the insertion part 180. Thus, in the first embodiment, the guiding function is achieved by the corner of the through hole 31 of the clutch housing 30 and the shooting part insertion part 172 of the retaining member 170.

[0143] It should be noted that the tutorial function can also be implemented as follows. Figure 18 This diagram shows a modified example of the state in which the insertion part 180 is inserted into the through hole 31 of the clutch housing 30 to supply grease to the corresponding part C on the near-front side. That is, as shown... Figure 18 As shown, it is also possible to not only make the insertion part 172 of the retaining member 170 and the corner of the through hole 31 of the clutch housing 30 corresponding to the corresponding part C on the front side (in) Figure 18 The flat portion 173 also contacts the corner portion of the clutch housing 30 that corresponds to the corresponding portion C on the near-front side in the through hole 31. Figure 18 The insertion part 180 is inserted into the right corner of the clutch housing 30, and the insertion part 172 of the retaining member 170 is in contact with the right corner of the clutch housing 30. This is an example of achieving the guiding function through the corner of the through hole 31 of the clutch housing 30, the insertion part 172 of the retaining member 170, and the flat part 173. It should be noted that in Figure 18 In this case, the angle θ1 is, for example, 100°.

[0144] In the following procedure, the operator performs the following operation: while looking at the screen displayed on the display unit 163 of the operating part 162 held by one hand (e.g., the right hand) (including an image of the tip 131 of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C near the front)), the operator moves the insertion part 180 held by the other hand (e.g., the left hand) toward the corresponding part C near the front in the direction of arrow AR4 (see reference). Figure 16 , Figure 17 Insert the tube 130A so that the tip 131 of the tube reaches the corresponding part C on the anterior side.

[0145] As the insertion part 180 is inserted toward the corresponding part C on the anterior side, the tip 131 of the grease supply tube 130A soon reaches a position P4 (refer to) that is closer to the previously predetermined distance from the corresponding part C on the anterior side. Figure 17 Next, reach position P3 near the corresponding part C on the anterior side (refer to...). Figure 17 ).

[0146] Thus, in order to visually determine the required insertion depth until the tip 131 of the grease supply tube 130A reaches a position P4 closer to the previously predetermined distance from the corresponding part C, and a position P3 near the corresponding part C, such as... Figure 11 As shown, the retaining component 170 is marked with a third scribing line L3 and a fourth scribing line L4. It should be noted that the retaining component 170 can also be marked with lines drawn with a universal pen or stickers instead of scribing lines L3 and L4.

[0147] The third line L3 is located at the top 131 of the grease supply tube 130A, reaching a position P4 that is closer to the previously specified distance than the corresponding part C (see reference). Figure 17 In the case where the top part 131 of the grease supply pipe 130A and the corresponding part C are in a predetermined positional relationship, the third scribing line L3 is aligned with the through hole 31 of the clutch housing 30.

[0148] Therefore, the operator visually confirms the positional relationship between the third scribe line L3 and the through hole 31 of the clutch housing 30, thereby ensuring that the top end 131 of the grease supply pipe 130A reaches a position P4 closer to the corresponding part C than a previously specified distance (see reference). Figure 17 The required insertion depth up to ) . Furthermore, it is possible to determine when the tip 131 of the grease supply tube 130A reaches a position P4 closer to the previously specified distance than the corresponding part C (refer to) Figure 17 ).

[0149] The fourth line L4 is located at position P3 near the corresponding part C at the top 131 of the grease supply tube 130A (see reference). Figure 17In the case where the top part 131 of the grease supply pipe 130A and the corresponding part C are in a predetermined positional relationship, the fourth scribing line L4 is aligned with the through hole 31 of the clutch housing 30.

[0150] Therefore, the operator visually confirms the positional relationship between the fourth scribe line L4 and the through hole 31 of the clutch housing 30, thereby determining the position P3 (see reference) until the top end 131 of the grease supply pipe 130A reaches the vicinity of the corresponding part C. Figure 17 The required insertion depth up to ) is determined. Furthermore, it is possible to determine when the tip 131 of the grease supply tube 130A reaches position P3 near the corresponding part C (see reference). Figure 17 ).

[0151] It should be noted that the third line L3 can also be omitted.

[0152] Next, when the fourth scribing line L4 aligns with the through hole 31 of the clutch housing 30, that is, when the top end 131 of the grease supply pipe 130A reaches the position P3 near the corresponding part C on the front side (refer to...). Figure 17 In the case of [missing information], as the third step, the operator inserts the tip 131 of the grease supply pipe 130A between the clutch release fork 21 (pressing part 21a) and the release bearing 15 (see [missing information]). Figure 17 The lubricant is supplied from the injection port 131a of the grease supply tube 130A to the corresponding portion C near the front. Specifically, the operator operates the grease supply unit 150 by holding it with the other hand (e.g., the left hand) while looking at the image displayed on the display unit 163 of the operation unit 162, which is held by one hand (e.g., the right hand). The image includes the top portion 131 of the grease supply tube 130A and its surrounding environment (e.g., the corresponding portion C near the front). Figure 11 The push rod 152 shown is pushed axially, thereby supplying grease from the injection port 131a of the grease supply pipe 130A to the corresponding part C near the front (see reference). Figure 17 ).

[0153] Next, after the grease supply to the corresponding part C on the front side is completed, as the fourth step, the operator pulls the grease supply pipe 130A out of the through hole 31 of the clutch housing 30.

[0154] Next, as the fifth step, in order to avoid interference between the insertion part 180 (grease supply tube 130A and endoscope 160A) inserted toward the corresponding part C on the far side and obstacles inside the clutch housing 30 (in addition, in order to ensure the field of view of the endoscope 160A), the operator positions the endoscope 160A at an appropriate angle relative to the grease supply tube 130A according to the layout of the internal structure of the clutch housing 30.

[0155] This is achieved by rotating the holding member 170, which holds the liposuction cannula 130A and the endoscope 160A, relative to the liposuction cannula 130A (see reference). Figure 19 Arrow AR2 in the middle), and make the winding end 174 on the side of the injection insertion part 171 of the retaining member 170 and the second scribe line L2 marked on the outer peripheral surface of the grease supply tube 130A (refer to the arrow AR2 in the middle), and make ... Figure 14 Consistent (refer to) Figure 19 ). Figure 19 This diagram shows the state in which the insertion part 180 is inserted into the through hole 31 of the clutch housing 30 in order to supply grease to the corresponding part C on the remote side. It should be noted that... Figure 19 From and Figure 17 The diagram is obtained by observing the through hole 31 from the direction opposite to the middle arrow AR4.

[0156] The second line L2 is set at an angle θ2 (reference) between the endoscope 160A and the fat supply canal 130A (baseline AX). Figure 19 In the case of the position, the winding end 174 on the injection insertion portion 171 side of the member 170 is kept aligned with the second scribe line L2. Figure 19 In this case, the angle θ2 is, for example, 75°.

[0157] Therefore, the operator visually confirms the positional relationship between the winding end 174 on the insertion side of the ejection portion 171 of the retaining member 170 and the second scribe line L2, thereby determining the position of the endoscope 160A relative to the grease supply tube 130A (reference line AX) at an angle θ2 (refer to...). Figure 19 The position of ).

[0158] Next, as the sixth step, the operator inserts the endoscope 160A into the insertion portion 180, positioned at the aforementioned angle θ2, through the through hole 31 of the clutch housing 30. At this time, as... Figure 19 As shown, the corner portion of the retaining member 170, which is inserted into the shooting portion 172, is aligned with the corresponding portion C on the far side in the through hole 31 of the clutch housing 30. Figure 19 The insertion part 180 is inserted by guiding the insertion direction of the insertion part 180 toward the corresponding part C on the far side. Thus, in the first embodiment, the guiding function is achieved by the corner of the through hole 31 of the clutch housing 30 and the shooting part insertion part 172 of the retaining member 170.

[0159] It should be noted that the tutorial function can also be implemented as follows. Figure 20 This diagram shows a modified example of inserting the insertion part 180 into the through hole 31 of the clutch housing 30 to supply grease to the corresponding part C on the remote side. That is, as shown... Figure 20As shown, it is also possible to make... Figure 15 The corner portion of the retaining member 170 after it has been reversed left and right, corresponding to the corresponding portion C on the far side in the through hole 31 of the clutch housing 30, is the insertion portion 172 of the retaining member 170 and the insertion portion C on the far side. Figure 20 The insertion part 180 is inserted while the left corner is in contact with the insertion part. This is achieved by performing the following steps between the fourth and fifth steps: pulling out the grease supply tube 130A and endoscope 160A from the holding member 170, reversing the holding member 170 left and right, and holding the grease supply tube 130A and endoscope 160A again through the reversed holding member 170.

[0160] Alternatively, the bootstrapping function can be implemented as follows. Figure 21 This diagram shows a modified example of inserting the insertion part 180 into the through hole 31 of the clutch housing 30 to supply grease to the corresponding part C on the remote side. That is, as shown... Figure 21 As shown, it is also possible to not only make the insertion part 172 of the retaining member 170 and the corner of the through hole 31 of the clutch housing 30 corresponding to the corresponding part C on the far side (in) Figure 21 The flat portion 173 also contacts the corner portion (located on the left side) of the through hole 31 in the clutch housing 30, corresponding to the corresponding portion C on the far side. Figure 21 The insertion part 180 is inserted into the left corner of the clutch housing 30, and the insertion part 172 of the retaining member 170 is in contact with the left corner of the clutch housing 30. This is an example of achieving the guiding function through the corner of the through hole 31 of the clutch housing 30, the insertion part 172 of the retaining member 170, and the flat part 173. It should be noted that in Figure 21 In this case, the angle θ2 is, for example, 100°.

[0161] In the following process, the operator performs the following operation: while looking at the screen (including an image of the tip 131 of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C on the remote side) displayed on the display unit 163 of the operation unit 162 which is held by one hand (e.g., the right hand), the operator inserts the insertion part 180 held by the other hand (e.g., the left hand) toward the corresponding part C on the remote side, so that the tip 131 of the grease supply tube 130A reaches the corresponding part C on the remote side.

[0162] As the insertion part 180 is inserted toward the corresponding part C on the far side, soon the tip 131 of the grease supply tube 130A reaches a position P4 closer to the previously predetermined distance than the corresponding part C on the far side (see reference). Figure 17 Next, reach position P3 near the corresponding part C on the far side (refer to...). Figure 17 ).

[0163] Next, when the fourth scribing line L4 aligns with the through hole 31 of the clutch housing 30, that is, when the top end 131 of the grease supply pipe 130A reaches the position P3 near the corresponding part C on the far side (refer to...). Figure 17 In the case of the seventh step, the operator inserts the tip 131 of the grease supply pipe 130A between the clutch release fork 21 (pressing part 21a) and the release bearing 15, and supplies grease from the injection port 131a of the grease supply pipe 130A to the corresponding part C on the remote side. Specifically, the operator operates the grease supply device 150 by holding it with the other hand (e.g., left hand) while looking at the image displayed on the display 163 of the operation unit 162 which is held by one hand (e.g., right hand) (including an image of the tip 131 of the grease supply pipe 130A and its surrounding environment (e.g., the corresponding part C on the remote side)). Figure 11 The push rod 152 shown is pushed along its axial direction, thereby supplying grease from the injection port 131a of the grease supply pipe 130A to the corresponding part C on the remote side.

[0164] Next, after the grease supply to the corresponding part C on the far side is completed, as the eighth step, the operator pulls the grease supply pipe 130A out of the through hole 31 of the clutch housing 30.

[0165] By implementing the above procedures, the grease supply to the corresponding part C on the near side and the corresponding part C on the far side is completed.

[0166] As described above, according to the first embodiment, the insertion part 180 can be inserted toward the corresponding part C without the use of a guide clamp.

[0167] This is because the guiding function is achieved through the through hole 31 (corner, etc.) of the clutch housing 30 and the retaining member 170 (shooting part insertion part 172, flat part 173).

[0168] Furthermore, according to the first embodiment, the endoscope 160A can be positioned at an appropriate angle relative to the fat supply tube 130A.

[0169] This is because a retaining member 170 is provided to hold the liposuction tube 130A and the endoscope 160A in a state where they are arranged side by side adjacent to each other, and the liposuction tube 130A is provided with an ejection part side mark (e.g., scribing lines L1, L2), so that the retaining member side mark of the retaining member 170 (e.g., the winding end 174 on the ejection part insertion part 171 side of the retaining member 170) is consistent with the ejection part side mark (e.g., scribing lines L1, L2).

[0170] Furthermore, according to the first embodiment, grease can be supplied to the pressing portion 21a of the clutch release fork 21 even without removing the clutch housing 30 (or the manual transmission unit including the clutch housing 30) from the vehicle. This simplifies grease supply maintenance and improves workability.

[0171] Next, a first variation of the retaining member 170 of the first embodiment described above will be explained.

[0172] Figure 22 This is a perspective view of retaining member 170A, which is the first modified example. Figure 23 yes Figure 22 Sectional view of XXIII-XXIII.

[0173] like Figure 22 , Figure 23 As shown, the retaining member 170A includes: a third semi-cylindrical portion 175, which is an ejection insertion portion for pressing the grease supply tube 130A (the cylindrical portion on the base end side); a fourth semi-cylindrical portion 176 and a fifth semi-cylindrical portion 177, which are imaging insertion portions for pressing the endoscope 160A (the cylindrical portion on the base end side); a second connecting portion 178 connecting the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176; and a third connecting portion 179 connecting the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177.

[0174] The second connecting portion 178 is a flat portion that connects one end of the third semi-cylindrical portion 175 to one end of the fourth semi-cylindrical portion 176. This flat portion (the second connecting portion 178) extends along the tangential direction of the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176 (see reference). Figure 23 ).

[0175] The third connecting portion 179 is a flat portion that connects one end of the third semi-cylindrical portion 175 to one end of the fifth semi-cylindrical portion 177. This flat portion (the third connecting portion 179) extends along the tangential direction of the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177 (see reference). Figure 23 ).

[0176] The fourth semi-cylindrical portion 176 is formed with one end of the plate folded back into a semi-cylindrical shape. Similarly, the fifth semi-cylindrical portion 177 is formed with the other end of the plate folded back into a semi-cylindrical shape.

[0177] The third semi-cylindrical portion 175 is formed in the plate portion between the fourth semi-cylindrical portion 176 and the fifth semi-cylindrical portion 177.

[0178] The second connecting portion 178 is the plate portion between the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176. The third connecting portion 179 is the plate portion between the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177.

[0179] One end of the plate (free end) includes: a first force-applying part 190, which applies force to the fifth semi-cylindrical part 177 by inserting an endoscope 160A (cylindrical portion on the base end side) inserted into the fifth semi-cylindrical part 177; and a second force-applying part 191, which applies force to the third semi-cylindrical part 175 by inserting a grease supply tube 130A (cylindrical portion on the base end side) inserted into the third semi-cylindrical part 175.

[0180] The third semi-cylindrical portion 175 is fixed to the grease supply tube 130A (the cylindrical portion on the base end side) inserted into the third semi-cylindrical portion 175. This fixing can be performed by known methods such as adhesives or welding.

[0181] The retaining member 170A (plate) is made of synthetic resin or spring steel. That is, the retaining member 170A can be formed by injection molding of synthetic resin or by bending or pressure forming of plate-shaped spring steel.

[0182] As explained above, according to the first variation, the operator presses the endoscope 160A (the cylindrical portion at the base end) into the fourth semi-cylindrical portion 176 or the fifth semi-cylindrical portion 177 according to the layout of the internal structure of the clutch housing 30, thereby positioning the endoscope 160A at an appropriate angle relative to the grease supply tube 130A. This prevents interference between the insertion portion 180 (grease supply tube 130A and endoscope 160A) and obstacles inside the clutch housing 30 when the insertion portion 180 (grease supply tube 130A and endoscope 160A) is inserted toward the corresponding portion C.

[0183] Furthermore, according to the first modified example, the second connecting portion 178 and the third connecting portion 179 are flat portions. Therefore, compared with the second modified example described later, where the fourth connecting portion 178B and the fifth connecting portion 179B, which correspond to the second connecting portion 178 and the third connecting portion 179, are curved portions, the manufacturing cost of the retaining member 170A (processing costs, etc., for bending the second connecting portion 178 and the third connecting portion 179) can be suppressed.

[0184] Furthermore, according to the first variation, by implementing the same steps as the first to eighth steps described in the first embodiment, the same effect as the first embodiment can be achieved.

[0185] Next, a second variation of the first embodiment described above will be described.

[0186] Figure 24 This is a perspective view of retaining member 170B, which is a second variation. Figure 25 yes Figure 24 XXV-XXV sectional view.

[0187] The retaining member 170B is equivalent to a retaining member formed by replacing the second connecting portion 178, which is a flat portion, of the retaining member 170A (a first variation) with a fourth connecting portion 178B, which is a curved portion, and replacing the third connecting portion 179, which is a flat portion, of the retaining member 170A (a first variation) with a fifth connecting portion 179B, which is a curved portion. Furthermore, the third semi-cylindrical portion 175 is not fixed to the grease supply tube 130A (the cylindrical portion at the base end) inserted into the third semi-cylindrical portion 175. Otherwise, it is the same as the retaining member 170A (a first variation). Hereinafter, the description will focus on the differences from the retaining member 170A (a first variation), and the same reference numerals will be used for the same components, with appropriate omissions in the description.

[0188] like Figure 24 , Figure 25 As shown, the retaining member 170B includes: a third semi-cylindrical portion 175, which is an injection insertion portion for pressing the grease supply tube 130A (the cylindrical portion on the base end side); a fourth semi-cylindrical portion 176 and a fifth semi-cylindrical portion 177, which are imaging insertion portions for pressing the endoscope 160A (the cylindrical portion on the base end side); a fourth connecting portion 178B, which connects the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176; and a fifth connecting portion 179B, which connects the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177.

[0189] The fourth connecting part 178B is a curved part that connects one end of the third semi-cylindrical part 175 to one end of the fourth semi-cylindrical part 176.

[0190] The fifth connecting part 179B is a curved part that connects the other end of the third semi-cylindrical part 175 to one end of the fifth semi-cylindrical part 177.

[0191] The fourth connecting part 178B is the plate portion between the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176. The fifth connecting part 179B is the plate portion between the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177.

[0192] The retaining member 170B (plate) is made of synthetic resin or spring steel. That is, the retaining member 170B can be formed by injection molding of synthetic resin or by bending or pressure forming of plate-shaped spring steel.

[0193] As explained above, according to the second variation, the operator presses the endoscope 160A (the cylindrical portion at the base end) into the fourth semi-cylindrical portion 176 or the fifth semi-cylindrical portion 177 according to the layout of the internal structure of the clutch housing 30, thereby positioning the endoscope 160A at an appropriate angle relative to the grease supply tube 130A. This prevents interference between the insertion portion 180 (grease supply tube 130A and endoscope 160A) and obstacles inside the clutch housing 30 when the insertion portion 180 (grease supply tube 130A and endoscope 160A) is inserted toward the corresponding portion C.

[0194] Furthermore, according to the second variation, by implementing the same steps as the first to eighth steps described in the first embodiment, the same effect as the first embodiment can be achieved.

[0195] In the first embodiment described above, an example of using grease as a fluid was given, but the method is not limited thereto. For example, a liquid may also be used as a fluid. In this case, the corresponding part C is the part where liquid needs to be supplied. Furthermore, fluids other than grease or liquid may also be used as fluids.

[0196] Furthermore, in the first embodiment described above, an example of applying the injection device and insertion direction guidance method of the present invention to the vehicle field (grease injection maintenance of the clutch disengagement mechanism) was described, but it is not limited thereto. For example, the injection device and insertion direction guidance method of the present invention can also be applied to various fields other than the vehicle field, such as the medical field and the semiconductor field. For example, in the first embodiment described above, an example of the partition between the operator and the corresponding part C being the clutch housing 30 was described, but it is not limited thereto. That is, the partition between the operator and the corresponding part C can also be a partition corresponding to the field in which the injection device and insertion direction guidance method of the present invention are applied. Furthermore, in the first embodiment described above, an example of inserting the insertion part 180 into the corresponding part C while contacting the corner of the opening (e.g., the through hole 31) formed in the partition (e.g., the insertion direction of the insertion part 180 is guided toward the corresponding part C) was described, but it is not limited thereto. For example, if a cut (not shown) is formed in the partition between the operator and the corresponding part C, the insertion part 180 can be inserted toward the corresponding part C while the corner of the cut is brought into contact with the insertion part 180 (i.e., the insertion direction of the insertion part 180 is guided toward the corresponding part C).

[0197] The values ​​shown in the above embodiments are all examples, and appropriate values ​​different from them can certainly be used.

[0198] The above embodiments are merely examples in all respects. The invention is not to be limited by the description of the above embodiments. The invention can be practiced in a wide variety of other forms without departing from its spirit or essential characteristics.
