Description

Technical Field

[0001] This invention relates to an injection device. 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, in Japanese Patent Application Publication No. 2020-37949, the grease is supplied (applied) by injecting grease in the insertion direction, so it is impossible to supply (apply) grease in the direction that intersects with the insertion direction. Summary of the Invention

[0004] The present invention provides an injection device capable of supplying (coating) fluid (e.g., grease) in a direction intersecting the insertion direction.

[0005] The present invention relates to an ejection device having an insertion part. The insertion part is a member that is inserted into a corresponding part within a narrow space while being held by an operator. The insertion part includes an ejection part that serves as a fluid supply conduit closed at its tip. Furthermore, at least one fluid ejection port is formed on the side of the tip of the ejection part, communicating between the outer and inner peripheral surfaces of the tip and allowing fluid supplied via the ejection part to be ejected.

[0006] According to the above-described ejection device, fluid (e.g., grease) is ejected from an ejection port formed on the side of the top end of the ejection section, thus enabling the fluid to be supplied (applied) in a direction intersecting the insertion direction.

[0007] In the above-described ejection device, the orientation, position, number, size, and shape of the fluid ejection outlet can be appropriately selected according to the application.

[0008] In the above-described ejection device, the fluid ejection outlet may be formed in a plurality of circumferentially at the top end of the ejection section.

[0009] In the above-described ejection device, the total area of ​​the fluid ejection outlets disposed on the upper side when the insertion part is inserted in the horizontal direction may be greater than the total area of ​​the fluid ejection outlets disposed on the lower side when the insertion part is inserted in the horizontal direction.

[0010] In the above-described ejection device, the fluid ejection port may also be a conical shape in which the diameter of the outer peripheral surface of the top end of the ejection portion is small and the diameter of the inner peripheral surface of the top end of the ejection portion is large.

[0011] In the above-described ejection device, the insertion part may also include an imaging device configured to capture images of the tip of the ejection part, the fluid ejection outlet, and the surrounding environment of the tip and the fluid ejection outlet.

[0012] In the above-described ejection device, the imaging device may also be an endoscope.

[0013] Alternatively, the ejection device of the above-described scheme may also include a feeder and a flexible tube. Alternatively, the feeder may be configured to supply fluid to the insertion portion. Alternatively, the flexible tube may be configured to connect the insertion portion to the feeder.

[0014] The ejection device of the present invention can supply (apply) fluid (e.g., grease) in a direction that intersects the insertion direction. Attached Figure Description

[0059] Hereinafter, the grease supply device for the clutch disengagement mechanism, which is a first embodiment (reference example) of the present invention, will be specifically described with reference to the accompanying drawings. It should be noted that the present invention is not limited to the embodiments described below.

[0060] The grease supply device of the first embodiment 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 mixing after the manual transmission vehicle has been submerged in water / crossed a river.

[0061] Figure 1This is a schematic diagram illustrating the clutch disengagement mechanism of the first embodiment. (As shown) 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.

[0062] It should be noted that, Figure 1 The 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The clutch disengagement mechanism 20 includes a clutch disengagement fork 21, a disengagement fork support 22, and a release cylinder 23.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] Next, refer to Figure 2 , Figure 3 The grease supply device 100 of the first embodiment will now be described. The grease supply device 100 is a device that supplies grease to the contact portion between the pressing portion 21a of the clutch release fork 21 and the release bearing 15. The grease supply device 100 is configured such that: a second clamp 120 (insertion portion 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 portion 121) is pushed towards the corresponding portion C until the tip portion 131 of the grease supply pipe 130 provided in the second clamp 120 and the corresponding portion 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 1As shown, the corresponding part C is disposed in the internal space surrounded by the clutch housing 30. Here, the clutch housing 30 is 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.

[0075] 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.

[0076] 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 tube 130, a flexible tube 140, and a grease dispenser 150. Here, the grease supply device 100 is an example of the "injection device" of the present invention. The grease supply tube 130 is an example of the "injection section" of the present invention. Furthermore, the grease dispenser 150 is an example of the "supplyer" of the present invention. The first clamp 110 and the second clamp 120 are components for positioning the grease supply tube 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.

[0077] 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.

[0078] 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".

[0079] 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).

[0080] 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. Here, grease is an example of the "fluid" of the present invention. The grease supply pipe 130 is made of metal. An opening 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.

[0081] like Figure 3As 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 an example of the "imaging device" of the present invention. 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 portion 162 via a cable 161. By operating the operation portion 162, imaging of the internal structure of the clutch housing 30 via the endoscope 160 can be achieved. Images captured by the endoscope 160 (e.g., images including the tip 131 of the fat supply tube 130 and its surrounding environment (e.g., the corresponding part C)) can be displayed on the display unit 163 mounted on the operation unit 162.

[0082] The grease supply unit 150 consists of a cylinder 151 and a push rod 152 (piston) (see reference). Figure 3 The 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.

[0083] 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.

[0084] 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 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] As a first step, the first clamp 110 is fixed to the through hole 31 of the clutch housing 30. Here, the clutch housing 30 is also an example of the fixing object of the present invention.

[0090] Figure 10A and Figure 10B This diagram schematically illustrates a modified example of the first clamp 110. The first clamp 110D includes a base 111, a protrusion 112, and a first hole 113 for positioning. The first hole 113 is an insertion hole for inserting the grease supply tube 130, the endoscope 160, and the second clamp 120. Here, the first hole 113 is positioned offset from the center in the Y direction relative to the first clamp 110D. Thus, the grease supply device 100 can apply grease at different positions after inserting the first clamp 110D, by rotating the first clamp 110D 180 degrees and inserting it again. Figure 10A This is a schematic diagram of inserting the first clamp 110D. Figure 10B Is to make Figure 10A A schematic diagram showing the first clamp 110D rotating 180 degrees and being inserted. Figure 10A In this configuration, the first side 115A of the first clamp 110D becomes the contact surface that abuts against the clutch release fork 21. Figure 10B In this configuration, the second side 115B of the first clamp 110D becomes the contact surface that abuts against the clutch release fork 21. The grease supply tube 130 is positioned outward from the center of the endoscope 160 relative to the Y direction. It should be noted that, alternatively, the endoscope 160 may be positioned outward from the center of the grease supply tube 130 relative to the Y direction.

[0091] Figure 11 It means from Figure 9 A diagram of the first clamp 110 and the second clamp 120 that have been pulled out.

[0092] like Figure 11 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.

[0093] 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 ).

[0094] 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) 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.

[0095] 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.

[0096] 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.

[0097] 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 11 Push in.

[0098] 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 11 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 11 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.

[0099] The distance A1 between the base 111 and the key 116 of the first clamp 110 (refer to...) Figure 11 The thickness B1 of the portion surrounding the through hole 31 in the clutch housing 30 (refer to) Figure 11 The 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 11When 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.

[0100] 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.

[0101] 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 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. The base 111 and key 116 of the first clamp 110 are examples of the "engaging portion" of the present invention.

[0102] 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 arms of the two-pronged pressing portion 21a) (see reference). Figure 9 Similarly, the second hole 114 of the first clamp 110 extends toward the corresponding part C (the other arm of the pressing part 21a that is divided into two branches). It should be noted that the first clamp 110 can be removed from the clutch housing 30 by following the reverse steps described above.

[0103] 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.

[0104] like Figure 8As 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 arm of the pressing portion 21a, which is divided into two prongs. 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.

[0105] 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 ).

[0106] 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 clamping member and other internal structures. In this case, the operator can hold the stop part 122 side and move the second clamp 120 by shaking the top end of the insertion part 121 in the Y direction.

[0107] 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).

[0108] 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 the 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, thereby causing the side surface 121a (refer to...) Figure 2 The sliding process includes a parallel movement in the Y direction and a swaying motion that causes the tip 131 to oscillate left and right. This results in a position where the grease supply tube 130 does not contact the clamping member.

[0109] 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.

[0110] like Figure 9 As shown, in the fourth step, the tip 131 of the grease supply pipe 130 reaches the height h2 of one arm of the pressing part 21a of the two-strand structure. 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.

[0111] 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 9 In 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.

[0112] Then, when the grease supply in the fifth step is completed, the sixth step is to remove the grease supply pipe 130. In the sixth step, while keeping the first clamp 110 fitted into the through hole 31, the supply of grease to the tip 131 of the grease supply pipe 130 is stopped. After that, the second clamp 120 is pulled out from the through hole 31, and the tip 131 of the grease supply pipe 130 is also pulled out from the through hole 31 to the outside of the clutch housing 30.

[0113] For example, the second clamp 120 is pulled out from the insertion hole of the first clamp 110. When the second clamp 120 is pulled out from 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 or components other than the parts that need grease supply.

[0114] If the first to fifth steps described above are for the first hole 113, while maintaining the assembly state of the first clamp 110 toward the through hole 31, the second to fifth steps are performed for the second hole 114. This allows grease to be supplied to both arms of the two-strand pressing part 21a.

[0115] 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.

[0116] As explained above, according to the grease supply device 100 of 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. As a result, grease supply maintenance work becomes easier and workability is improved.

[0117] Next, the insertion amount control device 100A of the second embodiment (reference example) will be described.

[0118] Figures 12A-12C This is a schematic diagram of the insertion amount control device 100A according to the second embodiment. Figures 12A-12C The following describes the sequence of inserting the second clamp 120 into the first clamp 110.

[0119] The insertion depth control device 100A is used to visually control the position P1 (see reference) from outside the clutch housing 30 until the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C. Figure 9Or, a position P2 that is closer to the previously specified distance than the corresponding part C (refer to...). Figure 9 The means for determining the required insertion amount (hereinafter also referred to as the required insertion amount) of the second clamp 120 relative to the first clamp 110 up to the first clamp 110.

[0120] The insertion amount control device 100A has the same configuration as the grease supply device 100 of the first embodiment, but the difference is that the insertion part 121 of the second clamp 120 is marked with a first scribe line L1 and a second scribe line L2.

[0121] Hereinafter, the description will focus on the differences from the first embodiment. The same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 will be fixed to the clutch housing 30 (the portion around the through hole 31) in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions as described in the first embodiment above.

[0122] The first clamp 110 and the second clamp 120 can be made of either resin or metal.

[0123] like Figure 12A As shown, with regard to the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR4. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0124] Thus, in order to visually determine the position P2 (refer to) until the tip 131 of the grease supply tube 130 reaches a predetermined distance closer to the corresponding part C, the position is determined. Figure 9 ), the corresponding position P1 near part C (refer to) Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to the specified depth is as follows: Figure 12A As shown, the insertion part 121 of the second clamp 120 is marked with a first line L1 and a second line L2. It should be noted that the insertion part 121 of the second clamp 120 may also be marked with marks such as lines drawn with a universal pen or stickers instead of lines L1 and L2.

[0125] The first line L1 is located at the top end 131 of the fat supply tube 130, at a position P2 that is closer to the previously specified distance than the corresponding part C (see reference). Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, the first scribe line L1 reaches the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (e.g., overlapping with the guide flange F) (refer to...). Figure 12B ).

[0126] Therefore, the operator can visually confirm the positional relationship between the first scribe line L1 and the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) from the outside of the clutch housing 30, thereby knowing the position P2 (refer to) until the top end 131 of the grease supply pipe 130 reaches a predetermined distance closer to the corresponding part C than before. Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0127] The second line L2 is located at position P1 near the corresponding part C at the top 131 of the grease supply tube 130 (refer to...). Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, the second scribe line L2 reaches the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (e.g., overlapping with the guide flange F) (refer to...). Figure 12C ).

[0128] Therefore, the operator can visually confirm the positional relationship between the second scribe line L2 and the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) from the outside of the clutch housing 30, thereby determining the position P1 until the top end 131 of the grease supply pipe reaches the vicinity of the corresponding part C (see reference). Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0129] It should be noted that the line L1 can also be omitted.

[0130] As explained above, according to the second embodiment, the position P1 (see reference ) where the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C can be visually determined from outside the clutch housing 30. Figure 9 Or, a position P2 that is closer to the previously specified distance than the corresponding part C (refer to...). Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0131] Furthermore, according to the second embodiment, there are the following advantages. Specifically, the required insertion amount (stroke) until the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C varies for each vehicle model (each manual transmission unit). In this case, for each vehicle model (each manual transmission unit) with different required insertion amounts, a mark (e.g., a line drawn with a pen or sticker) indicating the arrival of the tip 131 of the grease supply pipe 130 at the first clamp 110 (e.g., the guide flange F of the first clamp 110) is pre-marked on the insertion portion 121 of the second clamp 120. Thus, one first clamp 110 can be used to supply grease to multiple vehicle models (multiple manual transmission units) with different required insertion amounts. That is, it is not necessary to prepare a first clamp 110 for each vehicle model (each manual transmission unit), thereby suppressing the increase in the types of first clamps 110 and the associated increase in investment (cost).

[0132] Next, the insertion amount control device 100B of the third embodiment (reference example) will be described.

[0133] Figures 13A-13B This is a schematic diagram of the insertion amount control device 100B according to the third embodiment. Figures 13A-13B The following describes the sequence of inserting the second clamp 120 into the first clamp 110.

[0134] The insertion amount control device 100B is used to determine, by touch (the feeling of the hand holding the second clamp 120) rather than by sight, whether the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.)

[0135] The insertion amount control device 100B has the same configuration as the grease supply device 100 of the first embodiment, but the difference is that the insertion part 121 of the second clamp 120 is provided with first protrusions p1a and p1b.

[0136] Hereinafter, the description will focus on the differences from the first embodiment. The same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 will be fixed to the clutch housing 30 (the portion around the through hole 31) in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions as described in the first embodiment above.

[0137] At least one of the first clamp 110 and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal.

[0138] like Figure 13A As shown, with regard to the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR5. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches position P1 near the corresponding part C (see reference). Figure 9 ).

[0139] Thus, in order to determine by touch (the feeling of the hand holding the second clamp 120) rather than by sight, the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The top end 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship), and the insertion part 121 of the second clamp 120 is provided with first protrusions p1a and p1b.

[0140] The first protrusions p1a and p1b are, for example, hemispherical protrusions. It should be noted that the first protrusions p1a and p1b are not limited to hemispherical shapes, but can also be protrusions of other shapes.

[0141] The first protrusions p1a and p1b are provided at the position P1 near the corresponding part C when the second clamp 120 is inserted toward the corresponding part C. (Refer to...) Figure 9 In the case of ), the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 13B ), and cause friction (frictional force) to occur between the first hole 113 (or the second hole 114) and the location.

[0142] In order to generate this friction, such as Figure 13A As shown, the diameter A2 (design size) of the first hole 113 (and the second hole 114) and the thickness B2 (design size) of the insertion portion 121 of the second clamp 120 including the first protrusions p1a and p1b are set to a relationship of A2 < B2.

[0143] Therefore, the operator can determine the position of the grease supply tube 130 by touch (the feeling of holding the second clamp 120) rather than by sight, as the second clamp 120 is inserted toward the corresponding part C. Figure 9 (The aforementioned friction).

[0144] As explained above, according to the third embodiment, the position P1 near the corresponding part C can be determined by touch (the feeling of the hand holding the second clamp 120) rather than by sight (see reference). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a prescribed positional relationship.)

[0145] This is because the first protrusions p1a and p1b are present, and as the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 reaches a position P1 near the corresponding part C (see reference). Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, it is inserted into the first hole 113 (or the second hole 114) (see reference). Figure 13B This causes friction (frictional force) to occur between the first hole 113 (or the second hole 114) and the first hole 113 (or the second hole 114).

[0146] Therefore, the operator can focus on the following operation: while looking at the screen displayed on the display unit 163 of the operating unit 162 held by one hand (e.g., the right hand) (including an image of the tip 131 of the grease supply tube 130 and its surrounding environment (e.g., the corresponding part C)), the operator inserts the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) toward the corresponding part C in the direction of arrow AR5, so that the tip 131 of the grease supply tube 130 reaches a position P1 near the corresponding part C (see reference). Figure 9 ).

[0147] Furthermore, according to the third embodiment, there are the following advantages. Specifically, as described above, when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114), the second clamp 120 is fixed to the first clamp 110 by the friction generated between the first protrusions p1a and p1b and the inner wall of the first hole 113 (or the second hole 114). Furthermore, the gap (void) G1 between the insertion portion 121 of the second clamp 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.

[0148] Therefore, even if the operator releases the hand holding the second clamp 120 when the aforementioned friction occurs, the position of the top part 131 of the grease supply tube 130 relative to the corresponding part C will not change (almost not change)

[0149] Therefore, under the aforementioned friction condition, that is, when the tip 131 of the grease supply tube 130 reaches the position P1 near the corresponding part C (refer to...), Figure 9In this case, release the other hand (e.g., the left hand) that was previously holding the second clamp 120, and use the freed hand (e.g., the left hand) to hold the fat dispenser 150 again to operate the fat dispenser 150 (e.g., to...). 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. That is, one operator can insert the second clamp 120 toward the corresponding part C, and then supply grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0150] Next, the insertion amount control device 100C of the fourth embodiment (reference example) will be described.

[0151] Figures 14A-14C This is a schematic diagram of the insertion amount control device 100C according to the fourth embodiment. Figures 14A-14C The following describes the sequence of inserting the second clamp 120 into the first clamp 110.

[0152] The insertion depth control device 100C is used to determine, by touch (the feeling of the hand holding the second clamp 120) rather than by sight, whether the tip 131 of the grease supply tube 130 has reached a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.)

[0153] The insertion amount control device 100C has the same configuration as the grease supply device 100 of the first embodiment, but the difference from the grease supply device 100 of the first embodiment is that the insertion portion 121 of the second clamp 120 is provided with first protrusions p1a and p1b, and second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0154] Hereinafter, the description will focus on the differences from the first embodiment. The same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 will be fixed to the clutch housing 30 (the portion around the through hole 31) in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions as described in the first embodiment above.

[0155] At least one of the first clamp 110 and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal.

[0156] like Figure 14A As shown, with regard to the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR6. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0157] Thus, in order to determine by touch (the feeling of the hand holding the second clamp 120) rather than by sight, the tip 131 of the grease supply tube 130 has reached a position P2 closer to the previously predetermined distance than the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 (The top end 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.) The insertion part 121 of the second clamp 120 is provided with first protrusions p1a and p1b. In addition, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0158] The first protrusions p1a and p1b, and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are, for example, hemispherical protrusions. It should be noted that the first protrusions p1a and p1b, and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are not limited to hemispherical shapes, but can also be protrusions of other shapes.

[0159] The first protrusions p1a and p1b are provided at the point where, during the operation of inserting the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 reaches a position P2 that is closer to the corresponding part C than a previously predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 In the case of [missing information], the first protrusions p1a and p1b are inserted into the position of the first hole 113 (or the second hole 114) (refer to [missing information]). Figure 14B , Figure 14C ).

[0160] The second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are along the insertion direction of the second clamp 120 (refer to...). Figures 14A-14C The arrows (AR6) in the image are configured as a column.

[0161] As the second clamp 120 is inserted toward the corresponding part C, the first protrusions p1a and p1b pass through the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) with friction between them.

[0162] In order to generate this friction, such as Figure 14A As shown, the diameter A3 (design dimension) of the first hole 113 (and the second hole 114) including the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) and the thickness B3 (design dimension) of the insertion portion 121 of the second clamp 120 including the first protrusions p1a and p1b are set to be A3 < B3.

[0163] Therefore, the operator can determine by touch (the feeling of the hand holding the second clamp 120) rather than by sight that, as the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 reaches a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 (The aforementioned friction). For example, when the second clamp 120 is inserted toward the corresponding part C, and the first protrusions p1a and p1b abut (or press against) the second protrusions p2a1 and p2b1, the operator can determine by touch (the feeling of the hand holding the second clamp 120) rather than by sight that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9(The aforementioned friction). Furthermore, during the operation of further inserting the second clamp 120 toward the corresponding part C, when the first protrusions p1a and p1b abut (or press against) the second protrusions p2a2 and p2b2 and pass through them, the operator can determine by touch (the feeling of the hand holding the second clamp 120) rather than by sight that the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The aforementioned friction).

[0164] As explained above, according to the fourth embodiment, the tip 131 of the grease supply tube 130 can be determined by touch (the feeling of the hand holding the second clamp 120) rather than by sight to determine that it has reached a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 Furthermore, the tip 131 of the grease supply tube 130 reaches the position P1 near the corresponding part C (refer to...). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a prescribed positional relationship.)

[0165] This is because the first protrusions p1a, p1b and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are present. During the insertion of the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 reaches a position P2 (refer to) that is closer to the previously predetermined distance from the corresponding part C. Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 In the case where the top end 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, friction (frictional force) is generated.

[0166] Therefore, the operator can focus on the following operation: while looking at the screen displayed on the display unit 163 of the operating unit 162 held by one hand (e.g., the right hand) (including an image of the tip 131 of the grease supply tube 130 and its surrounding environment (e.g., the corresponding part C)), the operator inserts the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) toward the corresponding part C in the direction of arrow AR6, so that the tip 131 of the grease supply tube 130 reaches a position P2 closer to the previously predetermined distance from the corresponding part C (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0167] Furthermore, according to the fourth embodiment, there are the following advantages. That is, as described above, at position P1 (refer to) near the corresponding portion C at the tip 131 of the grease supply tube 130. Figure 9 And when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 14C The second clamp 120 is fixed to the first clamp 110. Furthermore, the gap (void) between the insertion part 121 of the second clamp 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 about 0.5 mm.

[0168] Therefore, at position P1 near the corresponding part C at the tip 131 of the grease supply tube 130 (refer to...) Figure 9 And when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 14C Even if the operator releases the hand holding the second clamp 120, the position of the top part 131 of the grease supply tube 130 relative to the corresponding part C will not change (almost not change).

[0169] Therefore, the tip 131 of the grease supply tube reaches position P1 near the corresponding part C (refer to...). Figure 9 In this case, release the other hand (e.g., the left hand) that was previously holding the second clamp 120, and use the freed hand (e.g., the left hand) to hold the fat dispenser 150 again to operate the fat dispenser 150 (e.g., to...). 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. That is, one operator can insert the second clamp 120 toward the corresponding part C, and then supply grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0170] Furthermore, according to the fourth embodiment, there are the following advantages. Specifically, the required insertion amount (stroke) until the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C varies for each vehicle model (each manual transmission unit). In this case, for each vehicle model (each manual transmission unit) with different required insertion amounts, the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are pre-configured in such a way that friction (frictional force) is generated when the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C. Therefore, a single first clamp 110 can be used to supply grease to multiple vehicle models (multiple manual transmission units) with different required insertion amounts. That is, it is not necessary to prepare a first clamp 110 for each vehicle model (each manual transmission unit), thus suppressing the increase in the types of first clamps 110 and the associated increase in investment (cost).

[0171] Next, the variations will be explained. Figure 15 This is a schematic diagram of a modified example 100D of the insertion amount control device according to the fourth embodiment.

[0172] In the fourth embodiment, for example... Figure 14A The example shown is provided with first protrusions p1a and p1b in the insertion portion 121 of the second clamp 120, and second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110, but it is not limited to this example.

[0173] For example, it can also be like Figure 15 As shown, conversely, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided in the insertion part 121 of the second clamp 120, and first protrusions p1a and p1b are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0174] Furthermore, in the fourth embodiment, an example using three second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) on one side was described, but it is not limited to this. For example, four or more second protrusions p2a and p2b on one side may also be used.

[0175] Next, variations of the first to fourth embodiments described above will be explained.

[0176] In the first to fourth embodiments described above, an example of using grease as a fluid was given, but the method is not limited to this. For example, a liquid may also be used as a fluid. In this case, the corresponding part C is the part that needs to be supplied with liquid. Furthermore, fluids other than grease and liquid may also be used as fluids.

[0177] Furthermore, in the third and fourth embodiments described above, an example was given in which the first protrusions p1a and p1b are provided in the insertion portion 121 of the second clamp 120, but this is not a limitation. For example, if the second clamp 120 is omitted, the first protrusions p1a and p1b may also be provided in the grease supply tube 130.

[0178] Furthermore, in the first to fourth embodiments described above, an example of providing a liposuction tube 130 to the second clamp 120 was described, but the method is not limited thereto. For example, the liposuction tube 130 may be omitted. If this is done, narrow space inspection can be performed using the endoscope 160. In this case, the corresponding part C is the part where narrow space inspection is required. Furthermore, in the first to fourth embodiments described above, an example of providing an endoscope 160 to the second clamp 120 was described, but the method is not limited thereto. For example, the endoscope 160 may be omitted.

[0179] Furthermore, in the first to fourth embodiments described above, examples of applying the insertion amount control device of the present invention to the vehicle field (grease injection maintenance of the clutch disengagement mechanism) were described, but the invention is not limited thereto. For example, the insertion amount control device of the present invention can also be applied to various fields other than the vehicle field, such as the medical field. For example, in the first to fourth embodiments described above, examples of using the clutch housing 30 (the portion surrounding the through hole 31) as the fixing object were described, but the invention is not limited thereto. That is, a fixing object corresponding to the field in which the insertion amount control device of the present invention is applied can also be used as the fixing object. Similarly, in the first to fourth embodiments described above, examples of using the clutch housing 30 as a cover member were described, but the invention is not limited thereto. That is, a cover member corresponding to the field in which the insertion amount control device of the present invention is applied can also be used as the cover member.

[0180] Next, the ejection device of the fifth embodiment (reference example) will be described.

[0181] Figure 16 This is a diagram of the ejection device.

[0182] The ejection device of the fifth embodiment differs from that of the first embodiment in that it does not include the first clamp 110, the second clamp 120, and the retaining member 170. Hereinafter, the description will focus on the differences from the first embodiment, and the same reference numerals will be used for components identical to those in the first embodiment, with appropriate omissions in the description.

[0183] The ejection device of the fifth embodiment, like the first embodiment described above, includes an insertion part 180 (see reference) that is inserted into a corresponding part C in a narrow space while being held by an operator. Figure 16 The insertion part 180 includes a grease supply tube 130A, an endoscope 160A, and a retaining member 170. Hereinafter, similar to the first embodiment described above, the case between the clutch release fork 21 (pressing part 21a) and the release bearing 15, where the narrow space is a grease-supplying area (the area where grease needs to be supplied from the top end 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 22 The pressing part 21a is configured to clamp the two strands of the input shaft 3 within the clutch housing 30 using arms divided into two strands. It should be noted that... Figure 22 The diagram shows the corresponding part C on the near-front side, while the corresponding part C on the far-back side is located behind the release bearing 15 and is therefore not shown. Hereinafter, the corresponding part C on the near-front side will be referred to as "one corresponding part C", and the corresponding part C on the far-back side will be referred to as "the other corresponding part C".

[0184] The grease supply tube 130A, like the grease supply tube 130 of the first embodiment described above, is an elongated injection portion including a tip portion 131 for injecting grease. 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 part 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 that is laterally elongated (see reference). Figure 16 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.

[0185] 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.

[0186] In the latter case, when the grease supply tube 130A extends in a straight line as in the grease supply tube 130 of the first embodiment described above, 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.

[0187] Therefore, in the fifth 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.

[0188] The grease supply tube 130A has an opening 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.

[0189] 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.

[0190] 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.

[0191] Next, the retaining member 170 will be described.

[0192] like Figure 16 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.

[0193] Figure 17 yes Figure 16 Sectional views of XVII-XVII Figure 18 It is a three-dimensional view of component 170.

[0194] like Figure 17 , Figure 18 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.

[0195] 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 17 ).

[0196] 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).

[0197] 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.

[0198] Maintain the axial length L of component 170 (refer to) Figure 18 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).

[0199] 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.

[0200] 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).

[0201] Figure 19 This is a three-dimensional view of the grease supply tube 130A (the cylindrical part on the base end side).

[0202] like Figure 19 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 angular position relative to the liposuction cannula 130A. This will be described later. The scribe lines L1 and L2 are an example of the "ejaculation part side markings" of this invention. It should be noted that the ejaculation part 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.

[0203] Next, refer to Figures 20-22 The method of grease supply achieved through an injection device is described. Figure 20 , Figure 21 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 20 From and Figure 22 The diagram is obtained by observing the through hole 31 from the direction opposite to the middle arrow AR4. Figure 22 The 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.

[0204] 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 21 (etc.) are revealed.

[0205] The following is about the method. Figure 22An example of sequential fat donation is given for the corresponding portion C on the proximal anterior side and the corresponding portion C on the distal side. It should be noted that... Figure 22 In the middle, the corresponding part C on the far side is located behind the release bearing 15 and is therefore not shown.

[0206] 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.

[0207] 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 20 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 19 Consistent (refer to) Figure 20 ).

[0208] 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 20 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 20 In this case, 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 mark" of the present invention. It should be noted that the retaining member side mark is not limited to the winding end 174 on the injection insertion portion 171 side; it can also be other marks such as lines drawn on the retaining member 170 with a pen or sticker. 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 16 Extend in a parallel direction (refer to) Figure 16 ).

[0209] 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 at an angle θ1 relative to the grease supply tube 130A (reference line AX). Figure 20 The position of ).

[0210] 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 20 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 20 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 fifth embodiment, the guiding function is achieved through the corner of the through hole 31 of the clutch housing 30 and the shooting part insertion part 172 of the retaining member 170.

[0211] It should be noted that the bootstrapping function can also be implemented as follows. Figure 23 This is a modified example showing 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 in the figure. Figure 23 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 23 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 23 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 23 In this case, the angle θ1 is, for example, 100°.

[0212] 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 21 , Figure 22 Insert the tube 130A so that the tip 131 of the tube reaches the corresponding part C on the anterior side.

[0213] 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 that is closer to the previously predetermined distance from the corresponding part C on the anterior side (see reference). Figure 22 Next, reach position P3 near the corresponding part C on the anterior side (refer to...). Figure 22 ).

[0214] 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, as... Figure 16 As shown, the retaining component 170 is marked with a third line L3 and a fourth 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 the lines L3 and L4.

[0215] The third line L3 is located at the top 131 of the grease supply tube 130A, at a position P4 that is closer to the previously specified distance than the corresponding part C (see reference). Figure 22 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.

[0216] 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 22 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 22 ).

[0217] 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 22 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 fourth scribing line L4 is aligned with the through hole 31 of the clutch housing 30.

[0218] 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 22 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 22 ).

[0219] It should be noted that the third line L3 can also be omitted.

[0220] 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 22 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 22 The lubricant is supplied from the opening 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 16 The push rod 152 shown is pushed along its axial direction, thereby supplying grease from the opening 131a of the grease supply pipe 130A to the corresponding part C near the front (see reference). Figure 22 ).

[0221] Next, after the grease supply to the corresponding part C on the near 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.

[0222] 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.

[0223] 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 24 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 19 Consistent (refer to) Figure 24 ). Figure 24 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 24 From and Figure 22The diagram is obtained by observing the through hole 31 from the direction opposite to the middle arrow AR4.

[0224] The second line L2 is positioned at an angle θ2 relative to the fat supply canal 130A (reference line AX) on the endoscope 160A. Figure 24 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 24 In this case, the angle θ2 is, for example, 75°.

[0225] 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 second scribe line L2, thereby determining the position of the endoscope 160A at an angle θ2 relative to the grease supply tube 130A (reference line AX). Figure 24 The position of ).

[0226] Next, as the sixth step, the operator inserts the endoscope 160A into the clutch housing 30 through the through hole 31, with the insertion part 180 positioned at the aforementioned angle θ2. At this time, as... Figure 24 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 24 The insertion part 180 is inserted while guiding the insertion direction of the insertion part 180 toward the corresponding part C on the far side. Thus, in the fifth 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.

[0227] It should be noted that the bootstrapping function can also be implemented as follows. Figure 25 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 25 As shown, it is also possible to make... Figure 20 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 25 The insertion part 180 is inserted while the left corner of the middle part is in contact. This is achieved by performing the following steps between the fourth and fifth steps: the grease supply tube 130A and the endoscope 160A are pulled out from the holding member 170, the holding member 170 is reversed left and right, and the grease supply tube 130A and the endoscope 160A are held again by the left and right reversed holding member 170.

[0228] Alternatively, the bootstrapping function can be implemented as follows. Figure 26 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 26 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 26 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 26 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 26 In this case, the angle θ2 is, for example, 100°.

[0229] 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.

[0230] 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 22 Next, reach position P3 near the corresponding part C on the far side (refer to...). Figure 22 ).

[0231] 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 22In 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, supplying grease from the opening 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). The image includes the tip 131 of the grease supply pipe 130A and its surrounding environment (e.g., the corresponding part C on the remote side). Figure 16 The push rod 152 shown is pushed along its axial direction, thereby supplying grease from the opening 131a of the grease supply pipe 130A to the corresponding part C on the far side.

[0232] 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.

[0233] 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.

[0234] As explained above, according to the fifth embodiment, the insertion part 180 can be inserted toward the corresponding part C without using a guide clamp.

[0235] 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).

[0236] Furthermore, according to the fifth embodiment, the endoscope 160A can be positioned at an appropriate angle relative to the fat supply tube 130A.

[0237] This is because the ejection device has a retaining member 170 that 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, and the liposuction tube 130A is provided with ejection part side marks (e.g., scribing lines L1, L2), so that the retaining member side marks of the retaining member 170 (e.g., the winding end 174 on the side of the ejection part insertion part 171 of the retaining member 170) are consistent with the ejection part side marks (e.g., scribing lines L1, L2).

[0238] Furthermore, according to the fifth 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.

[0239] Next, a first variation of the retaining member 170 of the fifth embodiment described above will be described.

[0240] Figure 27 This is a perspective view of retaining member 170A, which is the first modified example. Figure 28 yes Figure 27 Sectional views of XXVIII-XXVIII.

[0241] like Figure 27 , Figure 28 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.

[0242] 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 28 ).

[0243] 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 28 ).

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0248] 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.

[0249] 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.

[0250] 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 angular position 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.

[0251] 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.

[0252] Furthermore, according to the first variation, by implementing the same steps as the first to eighth steps described in the fifth embodiment above, the same effect as the fifth embodiment above can be achieved.

[0253] Next, a second variation of the fifth embodiment described above will be described.

[0254] Figure 29 This is a perspective view of retaining member 170B, which is a second variation. Figure 30 yes Figure 29 XXX-XXX sectional view.

[0255] 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.

[0256] like Figure 29 , Figure 30 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.

[0257] 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.

[0258] 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] Furthermore, according to the second variation, by implementing the same steps as the first to eighth steps described in the fifth embodiment above, the same effect as the fifth embodiment above can be achieved.

[0263] In the fifth embodiment described above, an example of using grease as a fluid was given, but the method is not limited to this. For example, a liquid may also be used as a fluid. In this case, the corresponding part C is the part that needs to be supplied with liquid. Furthermore, fluids other than grease and liquid may also be used as fluids.

[0264] Furthermore, in the fifth 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 fifth 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 fifth embodiment described above, an example of inserting the insertion part 180 towards the corresponding part C while contacting the corner of the opening (e.g., through hole 31) formed in the partition between the operator and the corresponding part C (e.g., guiding the insertion direction of the insertion part 180 towards 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 contacting the corner of the cut (i.e., while guiding the insertion direction of the insertion part 180 toward the corresponding part C).

[0265] Next, as a sixth embodiment, a configuration example in which grease can be supplied (applied) in a direction intersecting the insertion direction will be described. This configuration example can be applied to the first to fifth embodiments described above.

[0266] Figure 31 This is a perspective view of a configuration example that can supply (apply) grease in a direction intersecting the insertion direction ARa. Figure 32 It is a cross-sectional view near the top end 202 of the ejection section 201 (a cross-sectional view obtained based on a plane containing the central axis of the ejection section 201). Figure 33 This is a perspective view of a configuration example (modified example) that can supply (apply) lubricating grease in a direction intersecting the insertion direction ARa.

[0267] like Figure 31 As shown, an example of a configuration capable of supplying (applying) lubricant in a direction intersecting the insertion direction ARa includes an insertion part 200 that can be inserted into a corresponding part C within a narrow space while being held by an operator. Hereinafter, the corresponding part C is an annular member E (see reference) disposed within an internal space surrounded by a cover member. Figure 34 The example of the inner circumferential surface of the ring member E will be described below. Hereinafter, it will also be referred to as the inner circumferential surface C of the ring member E. The cover member is, for example, the clutch housing 30 of the first to fifth embodiments described above, but is not limited thereto. That is, cover members used in various fields other than the vehicle field, such as the medical field and the semiconductor field, can also be used as cover members. Although not shown, the cover member has a through hole identical to the through hole 31 of the clutch housing 30 into which the insertion part 200 is inserted.

[0268] The insertion part 200 includes an ejection part 201. The ejection part 201 is a fluid supply line whose tip portion 202 (tip surface) is closed by a sealing part 203. The ejection part 201 can be, for example, the grease supply tube 130 of the first to fourth embodiments where the tip portion 202 (tip surface) is closed by the sealing part 203, or the grease supply tube 130A of the fifth embodiment where the tip portion 202 is closed by the sealing part 203. The ejection part 201 (including the tip portion 202) can be a circular tube (see reference). Figure 31 It can also be a rectangular tube (see reference). Figure 33 It can also be a tube of other shapes. Although not shown, the insertion part 200 includes a camera part. The camera part is, for example, the endoscope 160 of the first to fourth embodiments and the endoscope 160A of the fifth embodiment.

[0269] An ejection port 204 is formed on the side of the top end portion 202 of the ejection portion 201. For example... Figure 32 As shown, the injection port 204 is an injection port that connects the outer peripheral surface 202a and the inner peripheral surface 202b of the top end portion 202 and allows grease supplied via the injection portion 201, which serves as a fluid supply conduit, to be injected. Here, the injection port 204 is an example of the "fluid injection port" of the present invention.

[0270] The orientation, location, quantity, size, and shape of the injection outlet 204 can be set appropriately according to the application.

[0271] For example, such as Figure 31 As shown, a plurality of injection ports 204 can be formed in a circumferential annular shape on the side surface of the top end portion 202 of the injection section 201. In this case, each injection port 204 can be formed radially, so that grease is ejected radially from each injection port 204. It should be noted that there can also be only one injection port 204.

[0272] In addition, for example, such as Figure 32 As shown in the upper layer, the shape of the injection port 204 can be a cylindrical shape with the same diameter between the outer peripheral surface 202a side and the inner peripheral surface 202b side of the top end portion 202 of the injection portion 201. Furthermore, for example, as... Figure 32 As shown in the lower layer, the shape of the injection port 204 can also be a conical shape with a small diameter on the outer peripheral surface 202a side of the top end portion 202 of the injection portion 201 and a large diameter on the inner peripheral surface 202b side of the top end portion 202 of the injection portion 201. Therefore, compared to the case where the injection port 204 is cylindrical, the dispersion distance of the grease ejected from the injection port 204 can be increased. Furthermore, the dispersion distance can be adjusted according to the operating speed of the grease dispenser 150 (e.g., the speed at which the grease is dispensed). Figure 3 The speed at which the push rod 152 is pushed axially (as shown) is used to adjust the grease dispersion distance ejected from the injection port 204. Furthermore, as... Figure 33 As shown, the shape of the injection port 204 can also be rectangular.

[0273] Next, an example of a configuration for uniformly supplying (coating) grease will be described.

[0274] Figure 34 This is an example of grease supply.

[0275] Figure 34 The upper layer indicates the case where grease is supplied (applied) to the inner circumferential surface C of the annular member E by the ejection portion 201, which is inserted into the through hole formed in the cover member and inserted vertically into the narrow space while the insertion portion 200 is held by the operator.

[0276] exist Figure 34The upper layer shows an example of horizontal grease application. Ideally, when the injection section 201 is inserted vertically and grease is supplied (applied) evenly, multiple injection ports 204 of the same size and shape are formed in a ring shape, circumferentially spaced and radially arranged on the side of the top end portion 202 of the injection section 201. If this is done, the same amount of grease is ejected radially and evenly in the horizontal direction from each injection port 204 of the vertically inserted injection section 201, and the amount of grease reaching the inner circumferential surface C of the annular member E from each injection port 204 is constant. Therefore, grease can be supplied (applied) evenly to the inner circumferential surface C of the annular member E.

[0277] On the other hand, Figure 34 The lower layer shows an example of vertical grease application. When the injection port 201 is inserted horizontally and grease is supplied (applied) evenly, the following problem exists: When the injection port 201 is inserted horizontally, the amount of grease reaching the inner circumferential surface C of the annular member E is less due to its own weight compared to the grease injected from the lower injection port 204. Therefore, it is impossible to supply (apply) grease evenly to the inner circumferential surface C of the annular member E.

[0278] Therefore, when the injection section 201 is inserted horizontally and grease is supplied (applied) evenly, it is ideal that, taking into account the weight of the grease ejected from each injection port 204, the total area of ​​the injection ports 204 located on the upper side when the insertion section 200 is inserted horizontally is greater than the total area of ​​the injection ports 204 located on the lower side when the insertion section 200 is inserted horizontally, so that the amount of grease reaching the inner circumferential surface C of the annular member E from each injection port 204 becomes uniform.

[0279] This can be achieved, for example, by making the number of ejection ports 204 disposed on the upper side when the insertion part 200 is inserted in the horizontal direction greater than the number of ejection ports 204 disposed on the lower side when the insertion part 200 is inserted in the horizontal direction. Alternatively, it can be achieved, for example, by making the size of the ejection ports 204 disposed on the upper side when the insertion part 200 is inserted in the horizontal direction larger than the size of the ejection ports 204 disposed on the lower side when the insertion part 200 is inserted in the horizontal direction.

[0280] It should be noted that the grease supply device 150 can also be indicated by specifying the position of the push rod 152 of the grease supply device 150 into the cylinder 151, or by indicating a specified amount of one-push, or by using an automatic injection gun capable of metering grease supply instead of the cylinder 151 and the push rod 152 (piston) as the grease supply device 150. This allows for more stable grease supply (application) to the corresponding part C (e.g., the inner circumferential surface of the annular member E), ensuring the quality of the grease supply (application) operation to the corresponding part C (e.g., the inner circumferential surface of the annular member E).

[0281] As explained above, according to the sixth embodiment, grease is ejected from the ejection port 204 formed on the side of the top portion 202 of the ejection portion 201, so that the grease can be supplied (applied) in a direction that intersects the insertion direction ARa.

[0282] Next, the variations will be explained.

[0283] In the sixth embodiment described above, an example of using grease as a fluid was given, but the method is not limited to this. For example, a liquid may also be used as a fluid. In this case, the corresponding part C is the part that needs to be supplied with liquid. Furthermore, fluids other than grease and liquid may also be used as fluids.

[0284] Furthermore, in the sixth embodiment described above, an example of applying the injection device of the present invention to the automotive field (grease injection maintenance of clutch disengagement mechanisms) was given, but it is not limited thereto. For example, the injection device of the present invention can also be applied to a wide variety of fields other than the automotive field, such as the medical field and the semiconductor field.

[0285] Furthermore, in the sixth embodiment described above, an example of the insertion part 200 having a camera part was given, but the invention is not limited to this. For example, the camera part may be omitted.

[0286] The values ​​shown in the above embodiments are all examples, and appropriate values ​​different from them can certainly be used.

[0287] 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.
