[0057] Hereinafter, a grease supply device for the clutch disengagement mechanism will be used as a first embodiment (reference example) of the present invention, and will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the embodiments described below.

[0058] First Implementation Method

[0059] The grease supply device of the first embodiment is used to perform maintenance and grease injection in a low cost and short time to address the poor sliding caused by grease leakage from the grease lubrication part of the shift fork in the MT (manual transmission) clutch housing and the introduction of foreign matter after the manual transmission vehicle has been submerged in water / crossed a river, resulting in poor sliding (e.g., poor sliding accompanied by increased friction, abnormal noise, etc.).

[0060] Figure 1 This 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 for housing 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.

[0061] It should be noted that, Figure 1The X direction, as shown, represents the axial direction along the central axis, and the Z direction represents the direction orthogonal to the central axis (sometimes referred to as the radial or height direction). When the Z direction is set as the height direction, the upper side is sometimes referred to as the top end side, and the lower side as the base end side. Furthermore, the Y direction, described later, represents the direction orthogonal to both the X and Z directions. Sometimes the Y direction is referred to as the width direction.

[0062] 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.

[0063] The clutch disc 11 has a friction surface (clutch facing) sandwiched between the pressure plate 13 and the flywheel 16, and the clutch disc 11 is splinedly engaged with the input shaft 3 of the transmission. The rotation of the flywheel 16 is transmitted to the input shaft 3 through the friction between the friction surface of the clutch disc 11 and the flywheel 16. The flywheel 16 is bolted to the crankshaft 2 of the engine, and the flywheel 16 rotates integrally with the crankshaft 2.

[0064] 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.

[0065] 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.

[0066] 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 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.

[0067] The clutch release mechanism 20 includes a clutch release fork 21, a release fork support 22, and a release cylinder 23.

[0068] The clutch release fork 21 is a component for axially moving the release bearing 15 and is configured to rock 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.

[0069] 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, such that the input shaft 3 is sandwiched 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. The fork boot 32 may also have a hole (cooling hole) 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.

[0070] 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 is composed 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.

[0071] The release bearing 15 is configured to be axially movable 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 the 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.

[0072] 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, and the release bearing 15 moves axially, pushing 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 cut off from power transmission. When the operating force from the release cylinder 23 is released, there is no longer a pressing force from the pressing part 21a acting on the release bearing 15, thereby engaging the clutch body 10. When the clutch body 10 is engaged, the flywheel 16 and the clutch disc 11 are connected to transmit power. 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 by swinging the clutch release fork 21.

[0073] Next, the grease supply device 100 of the first embodiment will be described. The grease supply device 100 is a device that supplies grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15. The grease supply device 100 is configured such that: a second clamp 120 (insertion part 121) is inserted into the guide through hole (first hole 113, second hole 114) of the first clamp 110, which is fixed to the clutch housing 30 as described later, and the second clamp 120 (insertion part 121) is inserted toward the corresponding part C until the top end 131 of the grease supply pipe 130 provided in the second clamp 120 and the corresponding part C are in a predetermined positional relationship. Figure 1 As shown, corresponding part C refers to the contact portion between the clutch release fork 21 (pressing part 21a), which is a grease-requiring part (the part that needs to be supplied with lubricating grease from the top end 131 of the grease supply pipe 130), and the release bearing 15. Figure 1 As shown, the corresponding part C is disposed in the internal space surrounded by the clutch housing 30 (an example of the cover member of the present invention). A through hole (through hole 31) for clamp fixing is formed in the clutch housing 30, which communicates with the internal space.

[0074] When using a vehicle equipped with a clutch device 1 in environments 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 ideal to perform grease supply maintenance on the clutch disengagement mechanism 20 and to add 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.

[0075] like Figure 2 As shown, the grease supply device 100 is configured to include a first clamp 110, a second clamp 120, a grease supply pipe 130, a flexible pipe 140, and a grease dispenser 150. The first clamp 110 and the second clamp 120 are components used to position the grease supply pipe 130. The first clamp 110 is a component fitted into the through hole 31 of the clutch housing 30. The second clamp 120 is a component inserted into the insertion hole of the first clamp 110.

[0076] 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.

[0077] 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 formed in a row along the width direction of the first clamp 110, and are both through holes extending 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, unless otherwise specified, the first hole 113 and the second hole 114 are referred to as "insertion holes".

[0078] The second clamp 120 has: a prism-shaped insertion portion 121, inserted into the first hole 113 and the second hole 114 of the first clamp 110; and a stop portion 122, abutting 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 state of being inserted through the through hole 123. The endoscope 160 is fixed in the state of being inserted through the through hole 124 (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).

[0079] The grease supply pipe 130 is a pipe used to supply grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15 inside the clutch housing 30. The grease supply pipe 130 is an elongated ejection portion including a tip portion 131 for ejecting grease (an example of the fluid of the present invention). The grease supply pipe 130 is made of metal. An opening 131a for ejecting grease (hereinafter also referred to as ejection port 131a) 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.

[0080] like Figure 3 As shown, the grease supply device 100 includes an endoscope 160 as an imaging unit. The endoscope 160 is an elongated imaging device with an imaging section in its tip portion 160a, which captures images of the tip portion 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 in this tip portion 160a. The base end of the endoscope 160 is connected to the operation unit 162 via a cable 161. By operating the operation unit 162, imaging of the internal structure of the clutch housing 30 via the endoscope 160 can be achieved. The images captured by the endoscope 160 (e.g., images of the tip portion of the grease supply tube 130 and its surrounding environment (e.g., corresponding part C)) can be displayed on the display unit 163 mounted on the operation unit 162.

[0081] The grease supply unit 150 consists of a cylinder 151 and a push rod 152 (piston) (see reference). Figure 3The flexible tube 140 is connected to the cylinder 151 of the grease supply unit 150. By pushing the push rod 152 while the cylinder 151 is filled with grease, grease can be supplied from the grease supply unit 150 to the grease supply tube 130. For example, the grease supply tube 130 can be inserted into the clutch housing 30 through the through hole 31 while the grease supply tube 130 and the flexible tube 140 are pre-filled with grease, thereby smoothly performing grease supply achieved by operating the grease supply unit 150.

[0082] The tip 131 of the grease supply tube 130 has a reduced diameter 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, thereby enabling grease supply to the parts requiring grease supply through the narrow space within the clutch housing 30.

[0083] Here, refer to Figure 5 , Figures 6A-6C The first fixture 110 is described in detail. Figure 5 This is a top view of the base end side of the first clamp 110. Figure 6A It means Figure 5 The diagram of the A-direction view. Figure 6B This is a perspective view of the first clamp 110 viewed from the back side. Figure 6C It means Figure 5 A diagram of the VIC-VIC line cross section.

[0084] 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.

[0085] 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.

[0086] 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 engages with 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 in the protrusion 112 are also rectangular in shape, similar to the base end side. Figure 6C As shown, the first hole 113 extends linearly inside the protrusion 112.

[0087] Next, refer to Figures 7-9 The grease supply method performed 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 (see reference 130) in the clutch housing 30 for inserting the grease supply pipe 130, etc. Figure 2 , Figure 9 (etc.) are revealed.

[0088] As a first step, the first clamp 110 is fixed to the through hole 31 of the clutch housing 30 (an example of the fixing object of the present invention).

[0089] Figure 11 It means from Figure 9 Diagram of the first clamp 110 and the second clamp 120 that have been extracted.

[0090] 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.

[0091] 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 ).

[0092] Next, the first clamp 110 is moved along the clutch release fork 21 (plane 21d) towards the through hole 31 (refer to...). Figure 2 The arrow AR1 in the diagram slides and moves until the protrusion 112 of the first clamp 110 is inserted into the through hole 31 and the base 111 of the first clamp 110 abuts against the surrounding portion of the through hole 31 in the clutch housing 30.

[0093] 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.

[0094] 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.

[0095] Next, the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, will be positioned along the direction of arrow AR2 (refer to...). Figure 7 , Figure 11 Push it in.

[0096] 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 until the surrounding portion of the through hole 31 reaches the bottom 117 between the base 111 and the key portion 116 of the first clamp 110.

[0097] 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 11The relationship is set as A1 < B1. Therefore, when the first clamp 110 is positioned relative to the clutch housing 30 in the Y and Z directions as described above, along the direction of arrow AR2 (refer to...), Figure 7 , Figure 11 When pushed in, the portion surrounding the through hole 31 in the clutch housing 30 is inserted (pressed in) into the space between the base 111 and the key 116 of the first clamp 110. Thus, the first clamp 110 is fixed to the clutch housing 30.

[0098] Furthermore, the periphery of the through hole 31 in the clutch housing 30 touches 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.

[0099] As described above, the first clamp 110 is fixed to the clutch housing 30 (the portion surrounding the through hole 31) in a state where it is positioned relative to the clutch housing 30 (an example of the fixing object of the present invention) in the X, Y, and Z directions. In other words, the first clamp 110 engages with the portion surrounding the through hole 31 in the clutch housing 30 in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions. The base 111 and key 116 of the first clamp 110 are examples of the engaging portion of the present invention.

[0100] Thus, with the first clamp 110 fixed to the clutch housing 30 (the portion surrounding the through hole 31), the first hole 113 of the first clamp 110 extends toward the corresponding portion C (one of the pressing portions 21a) (see reference). Figure 9 Similarly, the second hole 114 of the first clamp 110 extends toward the corresponding part C (the pressing part 21a on the other side). It should be noted that the first clamp 110 can be removed from the clutch housing 30 by following the reverse order as described above.

[0101] 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, marking lines, as described later in the second embodiment, are marked at a predetermined distance from the top end. The outer periphery of the insertion portion 121 is rectangular. 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.

[0102] like Figure 8 As shown, the insertion portion 121 of the second clamp 120 is inserted into the first hole 113 of the first clamp 110, thereby extending the grease supply pipe 130 toward the pressing portion 21a of the clutch release fork 21, which is the part requiring grease supply. The pressing portion 21a has a two-pronged structure, so the grease supply pipe 130 inserted into the first hole 113 extends toward one of the pressing portions 21a. Sometimes it is necessary to avoid obstacles inside the clutch housing 30 until the grease supply pipe 130 reaches the vicinity of the pressing portion 21a of the clutch release fork 21. For example, a clip, which is a component of the release bearing 15, is an example of 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 encounter the clip before reaching the pressing portion 21a.

[0103] 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 line is reached. The second clamp 120 can be moved relative to the first clamp 110 within the insertion hole, so that in this second insertion state, the grease supply tube 130 and the endoscope 160 can 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 operating part 162 held by one hand (e.g., the right hand) (including an image of the top 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 towards 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 ).

[0104] 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 mark line, the grease supply tube 130 can be positioned at a height where it will not contact the clamping member of the release bearing 15 and avoid the clamping member and other internal structures. In this case, the stop part 122 side can be held by hand, and the top end side of the insertion part 121 can be moved by swinging in the Y direction.

[0105] like Figure 9 As shown, the height of the tip 131 of the grease supply tube 130 is such that it avoids the clamping member of the release bearing 15 at a height h1. 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 as to avoid the clamping member of the release bearing 15. This height h1 also represents the insertion amount (stroke amount).

[0106] For example, in the third step, after the side 121b of the insertion part 121 contacts the first surface 113a of the first hole 113, as an action to avoid obstacles within the clutch housing 30, the side 121a of the insertion part 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 part 121 slides on the third surface 113c of the first hole 113, so that the side 121a contacts the second surface 113b. This sliding includes a parallel movement in the Y direction and a rocking motion that swings the tip 131 laterally left and right. Thus, the grease supply pipe 130 is in a position where it does not contact the clamp.

[0107] 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 line, and the tip 131 of the grease supply pipe 130 is inserted into the area requiring grease supply.

[0108] like Figure 9 As shown, in the fourth step, the tip 131 of the grease supply pipe 130 reaches a height h2 where the pressing part 21a of one of the two structures is located. Thus, the tip 131 of the grease supply pipe 130 can be positioned near the pressing part 21a of the clutch release fork 21. The insertion depth at height h2 is greater than the insertion depth at height h1.

[0109] 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 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 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.

[0110] Then, when the grease supply in the fifth step is completed, the sixth step is to remove the grease supply tube 130. In the sixth step, while keeping the first clamp 110 fitted into the through hole 31, the grease at the tip 131 of the grease supply tube 130 is cut off. After that, the second clamp 120 is pulled out from the through hole 31, and the tip 131 of the grease supply tube 130 is also pulled out from the through hole 31 to the outside of the clutch housing 30.

[0111] 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 swing left and right through the gap between the insertion hole and the insertion part 121. As a result, grease can be prevented from adhering to parts and components other than the parts that need grease supply.

[0112] If the first to fifth steps described above are for the first hole 113, then the second to fifth steps, which target the second hole 114, are performed while maintaining the assembly state of the first fixture 110. This allows for grease supply to both sides of the pressing part 21a with its two-pronged structure.

[0113] It should be noted that if there are no obstructions inside the clutch housing 30 before reaching the point where grease needs to be supplied, the second and third steps described above can be omitted. In this case, the marking line on the second clamp 120 may not be required, and the fourth step can be performed after the first 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.

[0114] 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 100A can also apply grease to different locations by rotating it 180 degrees after inserting the first clamp 110D. Figure 10A This is a schematic diagram when the first clamp 110D is inserted. Figure 10B It is Figure 10A A schematic diagram showing the insertion of the first clamp 110D when it rotates 180 degrees. 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 10BIn 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 located outside the center of the endoscope 160 relative to the Y direction. It should be noted that, alternatively, the endoscope 160 may also be located outside the center of the grease supply tube 130 relative to the Y direction.

[0115] 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.

[0116] Second Implementation Method

[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 according to the second embodiment. Figures 12A-12C The following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0119] The insertion amount control device 100A is used to visually control the position P1 (see reference) near the corresponding part C from the top end 131 of the grease supply pipe 130 outside the clutch housing 30. Figure 9 ) or reach a position P2 that is closer to the 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 marking line L1 and a second marking line L2.

[0121] Hereinafter, the description will focus on the differences from the first embodiment, and 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 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

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

[0123] like Figure 12AAs shown, in 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 corresponding part C than a predetermined distance away (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 that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C by a predetermined distance (refer to...) 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 marking line L1 and a second marking line L2. It should be noted that the insertion part 121 of the second clamp 120 may also be marked with lines drawn with a magic marker or sticker instead of marking lines L1 and L2.

[0125] The first marking line L1 is set at a position P2 (refer to) where the tip 131 of the grease supply tube 130 has reached a predetermined distance closer than the corresponding part C. 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 marking line L1 reaches (e.g., overlaps with the guide flange F) the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (refer to...). Figure 12B ).

[0126] Therefore, by visually confirming the positional relationship between the first marking line L1 and the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) from outside the clutch housing 30, the operator can determine that the top end 131 of the grease supply pipe 130 has reached a position P2 closer to the corresponding part C by a predetermined distance (see reference). Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0127] The second marker line L2 is located at position P1 near the corresponding part C at the top end 131 of the grease supply tube 130 (refer to...). Figure 9In 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 marking line L2 reaches (e.g., overlaps with the guide flange F) the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (see reference). Figure 12C ).

[0128] Therefore, by visually confirming the positional relationship between the second mark 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, the operator can determine the position P1 (refer to) where the top end 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C. 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 marker line L1 can also be omitted.

[0130] As explained above, according to the second embodiment, the position P1 near the corresponding part C can be visually determined from outside the clutch housing 30 by the top end 131 of the grease supply pipe 130 (see reference). Figure 9 ) or reach a position P2 that is closer to the 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 marker line, a magic marker, or a sticker) is pre-marked on the insertion portion 121 of the second clamp 120 to indicate that the tip 131 of the grease supply pipe 130 has reached the vicinity of the corresponding part C before reaching the first clamp 110 (e.g., a guide flange F of the first clamp 110). Therefore, 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), thus suppressing the increase in investment (cost) as the number of types of first clamps 110 increases.

[0132] Third Implementation Method

[0133] Next, the insertion amount control device 100B of the third embodiment (reference example) will be described.

[0134] Figures 13A-13B This is a schematic diagram of the insertion amount control device according to the third embodiment. Figures 13A-13BThe following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0135] The insertion amount control device 100B is used to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) 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.)

[0136] 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 portion 121 of the second clamp 120 is provided with first protrusions p1a and p1b.

[0137] Hereinafter, the description will focus on the differences from the first embodiment, and 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 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0138] 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.

[0139] like Figure 13A As shown, in 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 ).

[0140] Thus, in order to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120), 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 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.

[0141] 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.

[0142] The first protrusions p1a and p1b are provided at position P1 (see reference) when the tip 131 of the grease supply tube 130 reaches the vicinity of the corresponding part C during the operation of inserting the second clamp 120 toward the corresponding part C. 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 the location where friction (friction force) is generated between the first hole 113 (or the second hole 114).

[0143] 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.

[0144] Therefore, the operator can determine the position of the grease supply tube 130 by touch (the feeling of the hand holding the second clamp 120) without visual inspection, as the second clamp 120 is inserted toward the corresponding part C. Figure 9 (The aforementioned friction).

[0145] As explained above, according to the third embodiment, it is possible to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) 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 prescribed positional relationship.)

[0146] 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 And friction (frictional force) is generated between it and the first hole 113 (or the second hole 114).

[0147] 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 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 ).

[0148] Furthermore, according to the third embodiment, there are the following advantages. That is, as described above, when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114), the friction generated between the first protrusions p1a and p1b and the inner wall of the first hole 113 (or the second hole 114) causes the second clamp 120 to be fixed to the first clamp 110. Furthermore, the gap (void) 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.

[0149] 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)

[0150] Therefore, under the aforementioned friction condition, that is, when the tip 131 of the grease supply tube 130 has reached the 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 free hand (e.g., the left hand) to hold the fat dispenser 150 again and operate it (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 perform the operation of inserting the second clamp 120 toward the corresponding part C, and then supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0151] Fourth Implementation Method

[0152] Next, the insertion amount control device 100C of the fourth embodiment (reference example) will be described.

[0153] Figures 14A-14C This is a schematic diagram of the insertion amount control device according to the fourth embodiment. Figures 14A-14C The following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0154] The insertion depth control device 100C is used to control the position P2 (see reference) of the tip 131 of the grease supply tube 130 to be closer to a predetermined distance than the corresponding part C, without visual inspection, but by touch (the feeling of the hand holding the second clamp 120). Figure 9 ) or the tip 131 of the grease supply tube 130 has reached 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 predetermined positional relationship.)

[0155] 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.

[0156] Hereinafter, the description will focus on the differences from the first embodiment, and 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 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0157] 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.

[0158] like Figure 14A As shown, in 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 corresponding part C than a 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 ).

[0159] Thus, in order to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120), that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9The tip 131 of the grease supply tube 130 has reached 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.

[0160] 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.

[0161] The first protrusions p1a and p1b are provided at a position P2 (see reference) where, during the operation of inserting the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance away. Figure 9 The tip 131 of the grease supply tube 130 has reached 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 ).

[0162] The second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are arranged in a row along the insertion direction of the second clamp 120 (refer to arrow AR6 in Figure 14).

[0163] Regarding the first protrusions p1a and p1b, as the second clamp 120 is inserted toward the corresponding part C, friction is generated between them and each of the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3), and friction is generated through each of the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3).

[0164] To generate this friction, such as Figure 14AAs 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.

[0165] Therefore, the operator can determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) that as the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 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 (or pass through) the second protrusions p2a1 and p2b1, the operator can determine by touch (the feeling of the hand holding the second clamp 120) that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than by visual inspection. 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 (or press against) the second protrusions p2a2 and p2b2 and have passed through the second protrusions p2a2 and p2b2, the operator can, without visual inspection, determine by touch (the feeling of the hand holding the second clamp 120) 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).

[0166] As explained above, according to the fourth embodiment, it is possible to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) 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 prescribed positional relationship.)

[0167] This is because the first protrusions p1a, p1b and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) have, during the operation of inserting the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 (refer to) that is closer to the corresponding part C by a predetermined distance. Figure 9 The tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 In the case where the top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, friction (frictional force) is generated.

[0168] 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 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 corresponding part C by a 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 ).

[0169] 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.

[0170] 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).

[0171] Therefore, the tip 131 of the grease supply tube 130 has reached 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 free hand (e.g., the left hand) to hold the fat dispenser 150 again and operate it (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 perform the operation of inserting the second clamp 120 toward the corresponding part C, and then supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0172] Furthermore, according to the fourth embodiment, there are the following advantages. Specifically, the required insertion amount (stroke) of the tip 131 of the grease supply pipe 130 until it 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, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are pre-configured to generate friction (frictional force) when the tip 131 of the grease supply pipe 130 has reached 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 number of types of first clamps 110 and the resulting increase in investment (cost).

[0173] Next, the modified examples will be explained.

[0174] Figure 15 This is a schematic diagram of the insertion amount control device (modified example) according to the fourth embodiment.

[0175] In the fourth embodiment, for example... Figure 14A As shown, an example is given in which first protrusions p1a and p1b are provided 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. However, this is not the only example.

[0176] For example, it can also be like Figure 15As 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.

[0177] 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.

[0178] Next, variations of the first to fourth embodiments described above will be explained.

[0179] In the first to fourth embodiments described above, an example using grease as the fluid was given, but the method is not limited to this. For example, a liquid may also be used as the fluid. In this case, the corresponding part C is the part that requires the supply of liquid. Furthermore, fluids other than grease or liquid may also be used as the fluid.

[0180] 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, the first protrusions p1a and p1b may be provided in the grease supply tube 130 without omitting the second clamp 120.

[0181] 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 this is not a limitation. For example, the liposuction tube 130 may be omitted. In this case, narrow space inspection can be performed using the endoscope 160. In this case, the corresponding part C is the part that needs to be inspected in a narrow space. Furthermore, in the first to fourth embodiments described above, an example of providing an endoscope 160 to the second clamp 120 was described, but this is not a limitation. For example, the endoscope 160 may be omitted.

[0182] 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 in 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.

[0183] Fifth Implementation Method

[0184] Next, the ejection device of the fifth embodiment (reference example) will be described.

[0185] Figure 16 This is a schematic diagram of the injection device 100D.

[0186] Compared to the first embodiment described above, the ejection device 100D of the fifth embodiment differs mainly in that it does not have the first clamp 110 and the second clamp 120, and it has the holding member 170. Hereinafter, the description will focus on the differences from the first embodiment described above, and the same reference numerals will be used for components that are the same as those in the first embodiment described above, and the description will be omitted as appropriate.

[0187] The ejection device 100D of the fifth embodiment is similar to that of the first embodiment described above, and includes an insertion part 180 (see reference) that is inserted into a corresponding part C in a narrow space when 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 of the clutch release fork 21 (pressing part 21a) and the release bearing 15, where the narrow space is the grease supply location (the location 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 the pressing part 21a that presses the release bearing 15 axially (see reference). Figure 22 The pressing part 21a is configured in a two-strand structure, with the top side divided into two strands, such that the input shaft 3 is sandwiched inside the clutch housing 30. It should be noted that... Figure 22 The figure shows the corresponding part C on the near front side, but the corresponding part C on the far side is located behind the release bearing 15 and is not shown.

[0188] Similar to the grease supply tube 130 of the first embodiment described above, the grease supply tube 130A is an elongated ejection portion including a tip portion 131 for ejecting lubricating grease (an example of the fluid of the present invention). This grease supply tube 130A is made of metal. To facilitate insertion of the tip portion 131 of the grease supply tube 130A between the clutch release fork 21 (pressing portion 21a), which is the 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 laterally elongated rectangular cross-section (see reference). Figure 16 The grease supply tube 130A is cylindrical except for the tip portion 131. It should be noted that the grease supply tube 130A may also be cylindrical, including the tip portion 131.

[0189] The layout of the internal structure of the clutch housing 30 sometimes varies depending on the vehicle model (or each manual transmission unit). Depending on the layout of the internal structure of the clutch housing 30, sometimes the path from the through hole 31 of the clutch housing 30 toward the corresponding part C into which the insertion part 180 (grease supply tube 130A and endoscope 160A) is inserted is straight, and sometimes the insertion path includes one or more bends along the way.

[0190] In the latter case, if the grease supply tube 130A extends in a straight line like the grease supply tube 130 in 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.

[0191] Therefore, in the fifth embodiment, assuming that the path of inserting the insertion part 180 (liposuction tube 130A and endoscope 160A) includes a bend in the middle, the portion C1 between the base end and the tip end is bent. Thus, even if there is a bend in the path of inserting the insertion part 180 (liposuction tube 130A and endoscope 160A), the insertion part 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 of inserting the insertion part 180 (liposuction tube 130A and endoscope 160A), sometimes multiple portions between the base end and the tip end of the liposuction tube 130A may be bent.

[0192] The grease supply tube 130A has an injection port 131a at its top end 131 (top surface) for injecting grease supplied through a cylindrical tube portion. A flexible tube 140 is connected to the base end of the grease supply tube 130A. The grease supply tube 130A is connected to the grease dispenser 150 via the flexible tube 140.

[0193] 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 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 of insertion into the insertion section 180 (liposuction tube 130A and endoscope 160A), sometimes multiple portions between the base and tip of endoscope 160A are bent.

[0194] 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 taken through the endoscope 160A. The image taken 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.

[0195] Next, the retaining member 170 will be described.

[0196] like Figure 16 As shown, the retaining member 170 holds the grease supply tube 130A and the endoscope 160A in a side-by-side adjacent configuration.

[0197] Figure 17 yes Figure 16 Sectional views of XVII-XVII, Figure 18 It is a three-dimensional view of component 170.

[0198] 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.

[0199] 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 ).

[0200] 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).

[0201] 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.

[0202] 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).

[0203] 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, the injection insertion portion 171 will elastically deform and be fixed to the grease supply tube 130A (the cylindrical portion on the base end side) by its restoring force.

[0204] Similarly, the diameter of the imaging insertion part 172 is slightly larger than the diameter of the endoscope 160A. Therefore, when the endoscope 160A is inserted, the imaging insertion part 172 will elastically deform and be fixed to the endoscope 160A (the cylindrical part on the base end side) by its restoring force, so that the imaging insertion part 172 is in close contact with the outer peripheral surface of the endoscope 160A (the cylindrical part on the base end side).

[0205] Figure 19 This is a three-dimensional view of the grease supply tube 130A (the cylindrical part on the base end side).

[0206] like Figure 19 As shown, a first marking line L1 and a second marking line L2 extending axially are marked on the outer peripheral surface of the liposuction cannula 130A. Marking lines L1 and L2 are used to position the endoscope 160A at an appropriate angle relative to the liposuction cannula 130A. This will be described later. Marking lines L1 and L2 are an example of the ejection section side markings of the present invention. It should be noted that the ejection section side markings are not limited to marking lines L1 and L2, and may also be other markings such as lines drawn with a magic marker or sticker on the outer peripheral surface of the liposuction cannula 130A.

[0207] Next, refer to Figures 20-22 The grease supply method performed by the injection device 100D 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 View the diagram of 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.

[0208] 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 insertion part 180 (see reference). Figure 21 (etc.) are revealed.

[0209] Below, in Figure 22 The example described below illustrates fat donation in the order of the corresponding portion C on the proximal 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 not shown.

[0210] 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 vision 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.

[0211] This is achieved by rotating the retaining member 170 relative to the liposuction canal 130A in a state that holds the liposuction canal 130A and the endoscope 160A (see reference). Figure 20Arrow AR5 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 first marking line L1 marked on the outer peripheral surface of the grease supply tube 130A (refer to the arrow AR5 in the middle), and make ... winding end 174 on the side of the injection Figure 19 Consistent (refer to) Figure 20 To achieve this.

[0212] The first marker line L1 is set at an angle θ1 relative to the endoscope 160A and the fat supply canal 130A (reference line AX). Figure 20 In the case of the position, the winding end 174 on the side of the injection insertion part 171 is aligned with the first marking line L1. Figure 20 In this case, the angle θ1 is, for example, 75°. The winding end 174 on the injection insertion portion 171 side is an example of the retaining member side marking of the present invention. It should be noted that the retaining member side marking is not limited to the winding end 174 on the injection insertion portion 171 side; it can also be other markings such as lines drawn on the retaining member 170 using a magic marker or sticker. It should be noted that the reference line AX is, for example, on the upper surface of the prism-shaped top end 131 relative to the grease supply tube 130A (see reference). Figure 16 Extending in a parallel direction (refer to) Figure 16 ).

[0213] Therefore, the operator visually confirms the positional relationship between the winding end 174 on the insertion part 171 side of the retaining member 170 and the first marking line L1, thereby determining the position of the endoscope 160A relative to the grease supply tube 130A (reference line AX) at an angle θ1 (refer to...). Figure 20 The position of ).

[0214] 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 notch 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 near the front side in the through hole 31 of the clutch housing 30. Figure 20 The insertion part 180 is inserted while guiding the insertion direction of the insertion part 180 toward the corresponding part C on the near front side. 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.

[0215] It should be noted that the bootstrapping function can also be implemented as follows. Figure 23This diagram shows a modified example of the clutch housing 30 with the insertion part 180 inserted into the through hole 31 to supply grease to the corresponding part C on the near-front side. That is, as shown... Figure 23 As shown, it is also possible that not only the insertion part 172 of the retaining member 170 is inserted, but also the corner part (in which the flat part 173 also corresponds to the corresponding part C near the front side in the through hole 31 of the clutch housing 30) is inserted. Figure 23 The insertion part 180 is inserted into the contact side (the right corner of the middle part). 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°.

[0216] In the following procedure, the operator performs 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 of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C on the near side)), the operator moves the insertion part 180 held by the other hand (e.g., the left hand) toward the corresponding part C on the near side 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.

[0217] As the insertion part 180 is inserted toward the corresponding part C on the anterior side, soon the tip 131 of the grease supply tube 130A reaches a position P4 that is closer to a predetermined distance than the corresponding part C on the anterior side (see reference). Figure 22 Next, the tip 131 of the grease supply tube 130A reaches position P3 near the corresponding part C on the anterior side (refer to...). Figure 22 ).

[0218] Thus, in order to visually determine the required insertion depth of the tip 131 of the grease supply tube 130A to reach a position P4 closer to the corresponding part C than a predetermined distance, and to reach a position P3 near the corresponding part C, such as... Figure 16 As shown, the retaining member 170 is marked with a third marking line L3 and a fourth marking line L4. It should be noted that markings such as lines drawn with a magic marker or stickers can also be used to mark the retaining member 170 instead of marking lines L3 and L4.

[0219] The third marker line L3 is located at the top end 131 of the grease supply tube 130A, at position P4, which is closer to the specified distance than the corresponding part C (see reference). Figure 22In the case where the top end 131 of the grease supply pipe 130A and the corresponding part C are in a predetermined positional relationship, the third marking line L3 is aligned with the through hole 31 of the clutch housing 30.

[0220] Therefore, the operator visually confirms the positional relationship between the third mark line L3 and the through hole 31 of the clutch housing 30, thereby determining the position P4 (refer to) where the top end 131 of the grease supply pipe 130A reaches a specified distance closer than the corresponding part C. Figure 22 The required insertion depth up to ) is determined. Furthermore, it allows monitoring to determine when the tip 131 of the grease supply tube 130A has reached a position P4 closer to a predetermined distance than the corresponding portion C (see reference). Figure 22 ).

[0221] The fourth marking line L4 is located at position P3 near the corresponding part C at the top end 131 of the grease supply tube 130A (see reference). Figure 22 In the case where the top end 131 of the grease supply pipe 130A and the corresponding part C are in a predetermined positional relationship, the fourth marking line L4 is aligned with the through hole 31 of the clutch housing 30.

[0222] Therefore, the operator visually confirms the positional relationship between the fourth mark line L4 and the through hole 31 of the clutch housing 30, thereby determining the position P3 (see reference) where 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 ascertain that the tip 131 of the grease supply tube 130A has reached position P3 near the corresponding part C (see reference). Figure 22 ).

[0223] It should be noted that the third marker line L3 can also be omitted.

[0224] Next, when the fourth mark 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 has reached 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 injection port 131a of the grease supply tube 130A to the corresponding part C near the front. Specifically, the operator, while looking at the image displayed on the display unit 163 mounted on the operating unit 162 held by one hand (e.g., the right hand) (including an image of the top of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C near the front), holds the grease dispenser 150 with the other hand (e.g., the left hand) and operates it (e.g., by...). Figure 16The push rod 152 shown is pushed axially, thereby supplying grease from the injection port 131a of the grease supply pipe 130A to the corresponding part C near the front (see reference). Figure 22 ).

[0225] Next, after the grease supply to the corresponding part C on the near front side is completed, as the fourth step, the operator pulls out the grease supply pipe 130A from the through hole 31 of the clutch housing 30.

[0226] Next, as the fifth 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 far side and obstacles inside the clutch housing 30 (in addition, to ensure the field of vision 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.

[0227] This is achieved by rotating the retaining member 170 relative to the liposuction canal 130A in a state that holds the liposuction canal 130A and the endoscope 160A (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 marking line L2 marked on the outer peripheral surface of the grease supply tube 130A (refer to the arrow AR2 in the middle), and make ... winding end 174 on the side of the injection Figure 19 Consistent (refer to) Figure 24 To achieve this. 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 to supply grease to the corresponding part C on the deeper side. It should be noted that... Figure 24 From and Figure 22 View the diagram of through hole 31 from the direction opposite to the middle arrow AR4.

[0228] The second marker line L2 is set at an angle θ2 relative to the endoscope 160A and the fat supply canal 130A (reference line AX). Figure 24 In the case of the position, the winding end 174 on the injection insertion part 171 side of the member 170 is kept aligned with the second marking line L2. Figure 24 In this case, the angle θ2 is, for example, 75°.

[0229] Therefore, the operator visually confirms the positional relationship between the winding end 174 on the insertion side of the ejection portion 171 of the retaining member 170 and the second marking line L2, thereby determining the position of the endoscope 160A relative to the grease supply tube 130A (reference line AX) at an angle θ2 (refer to...). Figure 24 The position of ).

[0230] Next, as the sixth step, the operator inserts the endoscope 160A into the insertion portion 180, positioned at the aforementioned angle θ2, through the through hole 31 of the clutch housing 30. At this time, as... Figure 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 of the through hole 31 in 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.

[0231] 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 far side. That is, as shown... Figure 25 As shown, it is also possible to make... Figure 20 The corner of the retaining member 170 after it has been reversed left and right, which corresponds to the corresponding part C on the far side in the through hole 31 of the clutch housing 30, is the insertion part 172 of the retaining member 170 and the insertion part 172 of the retaining member 170 after it has been reversed left and right. Figure 25 Insertion is performed by contacting one side of the left corner (the middle part). This is achieved by performing the following steps between the fourth and fifth steps: pulling out the grease supply tube 130A and endoscope 160A from the holding member 170, reversing the holding member 170 left and right, and using the reversed holding member 170 to hold the grease supply tube 130A and endoscope 160A again.

[0232] 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 far side. That is, as shown... Figure 26 As shown, not only the insertion portion 172 of the retaining member 170, but also the flat portion 173 can be aligned with the corner portion corresponding to the far side of the through hole 31 in the clutch housing 30 (in... Figure 26 The insertion part 180 is inserted into the contact side (the left corner of the middle part). 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°.

[0233] In the following process, the operator performs the following operation: while looking at the screen (including an image of the tip of the grease supply tube 130A and its surrounding environment (e.g., the corresponding part C on the far 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 far side, so that the tip 131 of the grease supply tube 130A reaches the corresponding part C on the far side.

[0234] As the insertion part 180 is inserted toward the corresponding part C on the deeper side, soon the tip 131 of the grease supply tube 130A reaches a position P4 closer to the predetermined distance than the corresponding part C on the deeper side (see reference). Figure 22 Next, the tip 131 of the grease supply tube 130A reaches position P3 near the corresponding portion C on the deep side (refer to...). Figure 22 ).

[0235] Next, when the fourth mark 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 has reached the position P3 near the corresponding part C on the far side (refer to...). Figure 22 In the case of the seventh step, the operator inserts the tip 131 of the grease supply tube 130A between the clutch release fork 21 (pressing part 21a) and the release bearing 15, and supplies grease from the injection port 131a of the grease supply tube 130A to the corresponding part C on the far side. Specifically, while looking at the image displayed on the display 163 of the operation unit 162, which is held by one hand (e.g., the right hand), the operator holds the grease supply device 150 with the other hand (e.g., the left hand) and operates it (e.g., by pressing the grease supply tube 130A). Figure 16 The push rod 152 shown is pushed along its axial direction, thereby supplying grease from the injection port 131a of the grease supply pipe 130A to the corresponding part C on the far side.

[0236] Next, after the grease supply to the corresponding part C on the far side is completed, as the eighth step, the operator pulls out the grease supply pipe 130A from the through hole 31 of the clutch housing 30.

[0237] 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.

[0238] As described above, according to the fifth embodiment, the insertion part 180 can be inserted toward the corresponding part C without the use of a guide clamp.

[0239] 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).

[0240] Furthermore, according to the fifth embodiment, the endoscope 160A can be positioned at an appropriate angle relative to the fat supply tube 130A.

[0241] This is because it has a retaining member 170 that holds the grease supply tube 130A and the endoscope 160A in a side-by-side arrangement, and the grease supply tube 130A is provided with an ejection part side mark (e.g., marking lines L1, L2) that matches the retaining member side mark (e.g., the winding end 174 on the ejection part insertion part 171 side of the retaining member 170).

[0242] 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.

[0243] Next, a first variation of the retaining member 170 of the fifth embodiment described above will be explained.

[0244] Figure 27 This is a perspective view of retaining member 170A, which is the first modified example. Figure 28 yes Figure 27 XXVIII-XXVIII sectional views.

[0245] like Figure 27 , Figure 28 As shown, the retaining member 170A includes: a third semi-cylindrical portion 175, which is an injection insertion portion for pressing in the fat supply tube 130A (the cylindrical portion on the base end side); a fourth semi-cylindrical portion 176, which is an imaging insertion portion for pressing in the endoscope 160A (the cylindrical portion on the base end side); a fifth semi-cylindrical portion 177; a second connecting portion 178, which connects the third semi-cylindrical portion 175 and the fourth semi-cylindrical portion 176; and a third connecting portion 179, which connects the third semi-cylindrical portion 175 and the fifth semi-cylindrical portion 177.

[0246] 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 ).

[0247] 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 ).

[0248] 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.

[0249] 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.

[0250] 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.

[0251] One end of the plate (free end) includes: a first force-applying portion 190, which applies force to the endoscope 160A (cylindrical portion on the base end side) inserted into the fourth semi-cylindrical portion 176 relative to the fourth semi-cylindrical portion 176; and a second force-applying portion 191, which applies force to the grease supply tube 130A (cylindrical portion on the base end side) inserted into the third semi-cylindrical portion 175 relative to the third semi-cylindrical portion 175.

[0252] 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.

[0253] 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.

[0254] As explained above, according to the first variation, the operator presses the endoscope 160A (the cylindrical portion at the base end) into the fourth semi-cylindrical portion 176 or the fifth semi-cylindrical portion 177 according to the layout of the internal structure of the clutch housing 30, thereby positioning the endoscope 160A at an appropriate angle relative to the grease supply tube 130A. This prevents interference between the insertion portion 180 (grease supply tube 130A and endoscope 160A) and obstacles inside the clutch housing 30 when the insertion portion 180 (grease supply tube 130A and endoscope 160A) is inserted toward the corresponding portion C.

[0255] 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.

[0256] Furthermore, according to the first variation, the same effect as the fifth embodiment can be achieved by performing the same steps as the first to eighth steps described in the fifth embodiment.

[0257] Next, a second variation of the fifth embodiment described above will be explained.

[0258] 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.

[0259] The retaining member 170B is equivalent to a retaining member obtained 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.

[0260] like Figure 29 , Figure 30 As shown, the retaining member 170B 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, which is an imaging insertion portion for pressing the endoscope 160A (the cylindrical portion on the base end side); a fifth semi-cylindrical portion 177; 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] Furthermore, according to the second variation, the same effect as the fifth embodiment can be achieved by implementing the same steps as the first to eighth steps described in the fifth embodiment.

[0267] 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 requires a supply of liquid. Furthermore, fluids other than grease or liquid may also be used as fluids.

[0268] 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 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 being the clutch housing 30 was described, but it is not limited thereto. That is, the partition between the operator and the corresponding part 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 into the corresponding part C while contacting the corner of the opening (e.g., the through hole 31) formed in the partition between the operator and the corresponding part (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 notch (not shown) is formed in the partition between the operator and the corresponding part, the insertion part 180 can be inserted toward the corresponding part C while the corner of the notch is brought into contact with the insertion part 180 (i.e., the insertion direction of the insertion part 180 is guided toward the corresponding part C).

[0269] Sixth Implementation Method

[0270] Next, as a sixth embodiment, a configuration example for removing foreign matter attached to the corresponding part C will be described. This configuration example can be applied to the first to fifth embodiments described above. Furthermore, this configuration example can be applied not only to removing foreign matter attached to the corresponding part C, but also to removing foreign matter attached to the vicinity of the corresponding part C.

[0271] Figure 31 , Figure 32 This is a perspective view of a configuration example for removing foreign matter attached to the corresponding part C.

[0272] like Figure 31 As shown, an example of a configuration for removing foreign objects attached to the corresponding part C includes an insertion part 200 that can be inserted into the corresponding part C in a narrow space while being held by an operator.

[0273] The insertion part 200 includes an ejection part 201. The ejection part 201 is a dual conduit including an inner conduit 202 and an outer conduit 203. The inner conduit 202 is a conduit with a first fluid ejection port 202a at its top end. The first fluid ejection port 202a is used to eject grease (the first fluid of the present invention, an example of a coating fluid) supplied to the inner conduit 202, for example, the grease supply pipe 130 of the first embodiment to the fourth embodiment, and the grease supply pipe 130A of the fifth embodiment. The grease supply device 205 is connected to the inner conduit 202 via a flexible tube 206. The grease supply device 205 is, for example, the grease supply device 150 of the first embodiment to the fifth embodiment. The grease supplied from the grease supply device 205 via the flexible tube 206 is supplied to the first fluid ejection port 202a via the inner conduit 202, and ejected from the first fluid ejection port 202a. The grease ejected from the first fluid ejection port 202a is supplied (coated) to the corresponding part C.

[0274] The outer conduit 203 is a conduit that forms a ring-shaped conduit 204 between the inner conduit 202 (outer circumferential surface) and the outer conduit 203. That is, by setting the outer conduit 203, the space surrounding the inner conduit 202 is effectively utilized as a ring-shaped conduit 204. Therefore, in conjunction with the following... Figure 34 Compared to the previous method, this method saves space. The annular pipe 204 can be formed, for example, by providing a spacer (not shown) between the inner pipe 202 (outer circumferential surface) and the outer pipe 203 (inner circumferential surface). This spacer can be, for example, a protrusion (multiple) formed by plastic deformation of a portion of the outer pipe 203 (inner circumferential surface), or other spacers.

[0275] The inner pipe 202 and the outer pipe 203 can be round pipes, rectangular pipes, or pipes of other shapes.

[0276] The annular conduit 204 is a conduit with a second fluid ejection port 204a at its top end. The second fluid ejection port 204a allows air (an example of the second fluid of the present invention, a foreign matter removal fluid) supplied to the annular conduit 204 to be ejected (jetted). An air source 207 is connected to the annular conduit 204. For example, as... Figure 32As shown, air source 207 is connected via a flexible tube 208 connected to a through hole 203a, which is formed at the base of the outer pipe 203 and communicates with the annular pipe 204. Air source 207 is, for example, an electrically operated air pump whose supply and stop can be switched by an operator. Air supplied from air source 207 via flexible tube 208 is supplied to a second fluid ejection port 204a via the annular pipe 204 and ejected (jetted) from the second fluid ejection port 204a. The air ejected from the second fluid ejection port 204a is blown toward the corresponding part C. Thus, foreign matter (e.g., mud, dust, grime, powder) adhering to the corresponding part C is removed (cleaned).

[0277] Furthermore, the insertion section 200 includes a camera section 220. The camera section 220 can be, for example, the endoscope 160 of the first to fourth embodiments and the endoscope 160A of the fifth embodiment. It should be noted that, from the viewpoint of preventing grease adhesion, the camera section 220 may also be positioned at a certain distance from the tip of the ejection section 201 (the first fluid ejection port 202a and the second fluid ejection port 204a).

[0278] Next, the method for removing foreign matter attached to the corresponding part C will be explained.

[0279] First, as the first step, the operator inserts the insertion part 200 through the through hole 31 of the clutch housing 30.

[0280] The operator performs the following procedures while looking at the screen (including images of the top end of the inner pipe 202, the top end of the annular pipe 204, and their surrounding environment (e.g., foreign objects attached to the corresponding part C) displayed on the display unit 163 of the operating unit 162 which is held with one hand (e.g., the right hand).

[0281] Next, as the second step, the operator performs the following operation: inserting the insertion part 200, which is held with the other hand (e.g., the left hand), toward the corresponding part C until the second fluid ejection port 204a reaches the vicinity of the corresponding part C where the foreign object is attached.

[0282] Next, as the third step, the operator operates the air source 207 to eject (jet) air from the second fluid ejection port 204a and blow this air toward the corresponding part C. By performing the above steps, foreign matter adhering to the corresponding part C can be removed (cleaned). It should be noted that in the second step described above, it is also possible to eject (jet) air from the second fluid ejection port 204a and insert the insertion part 200 toward the corresponding part C, and during the stage of supplying (applying) lubricating grease to the corresponding part C, operate the air source 207 to stop the ejection (jet) of air from the second fluid ejection port 204a.

[0283] As explained above, according to the sixth embodiment, foreign matter attached to the corresponding part C in a narrow space can be removed (cleaned) by blowing air ejected (jetted) from the second fluid ejection port 204a toward the corresponding part C.

[0284] Next, we will explain the variations.

[0285] Figure 33 This is a perspective view of a configuration example (modified example 1) for removing foreign matter attached to the corresponding part C.

[0286] like Figure 33 As shown, the top end of the inner pipe 202 can also protrude more than the top end of the outer pipe 203. This can prevent grease from clogging the second fluid injection port 204a.

[0287] Figure 34 This is a perspective view of a configuration example (modified example 2) for removing foreign matter attached to the corresponding part C.

[0288] In the sixth embodiment described above, an example of using an ejection section 201 as an ejection section having a dual pipeline including an inner pipeline 202 and an outer pipeline 203 was described, but it is not limited thereto.

[0289] For example, such as Figure 34 As shown, the ejection section 201 can also be a first pipe 210 and a second pipe 211 arranged side by side.

[0290] The first conduit 210 is a conduit with a first fluid ejection port 210a at its top end, through which grease supplied to the first conduit 210 is ejected. On the other hand, the second conduit 211 is a conduit with a second fluid ejection port 211a at its top end, through which air supplied to the second conduit 211 is ejected (jetted).

[0291] This variation can also achieve the same effect as the sixth embodiment described above.

[0292] In the sixth embodiment described above, an example of using grease as the first fluid was given, but the method is not limited thereto. For example, a liquid may also be used as the first fluid. In this case, the corresponding part C is the part that requires the supply of liquid. Furthermore, a fluid other than grease or liquid, such as solder (e.g., molten solder), may also be used as the first fluid. In this case, the corresponding part C is the part that requires the supply of solder.

[0293] Furthermore, in the sixth embodiment described above, an example of using a gas such as air (e.g., air at room temperature) as the second fluid was given, but it is not limited to this. For example, a liquid such as a cleaning solution may also be used as the second fluid. Furthermore, for example, when drying the corresponding part C, hot air (warm air) may be used as the second fluid. Furthermore, when cooling the corresponding part C, cold air (cold air) may be used as the second fluid.

[0294] 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.

[0295] Furthermore, in the sixth embodiment described above, an example of the insertion part 200 having a camera part 220 was given, but the invention is not limited thereto. For example, the camera part 220 may be omitted.

[0296] The values ​​shown in the above embodiments are examples, and appropriate values ​​different from those shown can of course be used.

[0297] The above-described embodiments are merely examples in all respects. The invention is not to be construed as limiting 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.
