Detailed Description

< First embodiment >, first embodiment

Referring to fig. 1 to 18, a front derailleur 30 for a human powered vehicle will be explained. The human powered vehicle 10 is a vehicle having at least one wheel, at least drivable by a human driving force. The human powered vehicle 10 includes various bicycles such as mountain bikes, road bikes, city bikes, freight bikes, hand bikes, and recumbent bikes. The number of wheels of the manually driven vehicle 10 is not limited. For example, the human powered vehicle 10 includes a wheelbarrow and a vehicle having more than two wheels. The manually driven vehicle 10 is not limited to a vehicle that can be driven only by a manual driving force. The human-powered vehicle 10 includes an electric bicycle (E-bike) propelled not only by human driving force but also by driving force of an electric motor. Electric bicycles (E-bike) include electric assist bicycles that are propelled assisted by an electric motor. In the following, in each embodiment, the manually driven vehicle 10 will be described as a bicycle.

In this specification, the following terms "front", "rear", "left", "right", "transverse", "above" and "below" and any other similar terms of direction refer to those directions determined based on a rider facing the handlebars in a reference position (e.g., saddle or seat) of the manually driven vehicle 10.

As shown in fig. 1, the manually driven vehicle 10 includes, for example, a frame 12, a crank shaft 14, a front sprocket 16, and a drive chain 18. The crank shaft 14 is rotatably mounted to the center shaft of the frame 12 about a crank axis C1. The front sprocket 16 is mounted to the crank arm or the crank shaft 14 so as to rotate about the crank axis C1. The drive chain 18 engages with the front sprocket 16 so as to move in the rotational direction of the front sprocket 16. In the case where the drive wheel of the human-powered vehicle 10 is a rear wheel, the rotation of the front sprocket 16 is transmitted to the rear wheel of the human-powered vehicle 10 via the rear sprocket by the drive chain 18. In the case where the drive wheel of the human powered vehicle 10 is the front wheel, the rotation of the front sprocket 16 can be transmitted to the front wheel by the drive chain 18.

The front sprocket 16 includes a plurality of sprockets of different diameters. The plurality of sprockets of different diameters include, for example, a first sprocket 16A and a second sprocket 16B. The diameter of the second sprocket 16B is larger than the diameter of the first sprocket 16A. The second sprocket 16B is mounted to a crank arm or crank shaft 14 of the human-powered vehicle 10 farther from the frame 12 of the human-powered vehicle 10 than the first sprocket 16A. The plurality of sprockets of different diameters may include more than three sprockets of different diameters. Three or more sprockets having different diameters are attached to the crankshaft 14 of the human-powered vehicle 10 such that the greater the diameter, the farther the sprocket is from the frame 12 of the human-powered vehicle 10.

The manually driven vehicle 10 includes, for example, a front derailleur 30. Front derailleur 30 operates to move drive chain 18 such that the sprocket engaged by drive chain 18 is changed from one of first sprocket 16A and second sprocket 16B to the other. The front derailleur 30 changes the gear ratio by shifting the drive chain 18 to change the sprocket engaged by the drive chain 18. The transmission ratio is, for example, a ratio of the rotational speed of the rear wheel of the human-powered vehicle 10 to the rotational speed of the crank shaft 14. The manual drive vehicle 10 includes, for example, a shift operation unit configured to be able to select a gear ratio. The shift operating portion is coupled to the front derailleur 30 via a bowden cable 20. The front derailleur 30 operates to change the speed ratio by changing the sprocket engaged by the drive chain 18 to a sprocket corresponding to the speed ratio selected by the shift operating portion.

As seen in FIG. 2, the front derailleur 30 is provided with a base member 32, an outer link 38 and an inner wire fixing structure 52. The base member 32 is configured to be coupled to the frame 12 of the human powered vehicle 10. The outer link 38 has a first outer link end 38A and a second outer link end 38B. The first outer link end 38A is rotatably connected to the base member 32 about the first outer link axis X1. In the installed state, at least a portion of the outer link 38 is farther from the frame 12 of the human-powered vehicle 10 than the base member 32. The mounted state is a state in which the front derailleur 30 is mounted to the frame 12 of the manually driven vehicle 10.

The base member 32 includes, for example, a frame mounting portion 34 and a main body portion 36. The frame mounting portion 34 is configured to mount the base member 32 to the frame 12 of the manually driven vehicle 10 in a mounted state. Fig. 2 shows an example of the case where the front derailleur 30 is in an installed state. The frame mounting portion 34 includes, for example, a clip 34A. The main body 36 is attached to the frame attachment 34 by, for example, bolts.

The main body portion 36 includes a bowden cable mounting portion 36A and an outer link urging member 36B. The bowden cable 20 includes, for example, an inner wire 20A, and an outer tube 20B that houses the inner wire 20A. The end of the outer tube 20B is attached to the bowden cable attachment portion 36A. The outer link urging member 36B urges the outer link 38 to rotate the outer link 38 about the first outer link axial center X1 in the first outer link rotation direction PL 1.

The front derailleur 30 is further provided with a chain guide 44, for example. The chain guide 44 is rotatably connected to the second outer link end 38B of the outer link 38 about the second outer link axis X2 to be configured to move between the retracted position PG1 and the extended position PG2 with respect to the base member 32. In the installed state, the extended position PG2 is farther from the frame 12 of the manually driven vehicle 10 than the retracted position PG 1.

The first outer link end 38A is configured to be rotatable with respect to the base member 32 about the first outer link axial center X1 in the second outer link rotational direction PL2 and the first outer link rotational direction PL 1. The second outer link end 38B is connected to the chain guide 44 so as to be rotatable about the second outer link axis X2.

The outer link 38 includes, for example, a first outer link shaft member 38X and a second outer link shaft member 38Y. The first outer link shaft member 38X connects the first outer link end 38A to the base member 32 such that the first outer link end 38A is rotatable about the first outer link axis X1. The axis of the first outer link shaft member 38X coincides with the first outer link axis X1. The second outer link shaft member 38Y connects the second outer link end 38B to the chain guide 44 such that the second outer link end 38B can rotate about the second outer link axle center X2. The axis of the second outer link shaft member 38Y coincides with the second outer link axis X2. The outer link 38 may not include the first outer link shaft member 38X and the second outer link shaft member 38Y. The first outer link end 38A can be directly connected to the base member 32 and the second outer link end 38B can be directly connected to the chain guide 44.

As shown in fig. 2 and 3, for example, the outer link 38 has a mounting hole 40. For example, the mounting hole 40 includes a mounting hole axis A1. The mounting hole axis A1 passes through the center axis of the mounting hole 40. The mounting hole 40 is, for example, a through hole that penetrates the outer link 38 in a direction parallel to the mounting Kong Zhouxin A1. The mounting hole 40 is formed, for example, at the first outer link end 38A. The first outer link axle center X1 and the second outer link axle center X2 are disposed substantially parallel to the mounting hole axle center A1, for example, in an assembled state of the front derailleur 30.

As seen in FIG. 2, the front derailleur 30 is further provided with an inner link 42. The inner link 42 has a first inner link end 42A and a second inner link end 42B. The first inner link end 42A is rotatably connected to the base member 32 about the first inner link axis Y1.

At least a portion of the outer link 38 is disposed farther from the frame 12 of the manually driven vehicle 10 than the base member 32, as viewed in a direction parallel to the mounting hole axis A1. At least a portion of the inner link 42 is disposed farther from the frame 12 of the manually driven vehicle 10 than the base member 32 in the mounted state, as viewed in a direction parallel to the mounting hole axis A1.

For example, in the installed state, at least a portion of the outer link 38 is farther from the frame 12 of the human-powered vehicle 10 than the inner link 42. For example, in the installed state, the outer link 38 is farther from the frame 12 of the human-powered vehicle 10 than the inner link 42. As shown in fig. 2, the outer link 38 is disposed farther from the frame 12 of the manually driven vehicle 10 than the inner link 42 when viewed in a direction parallel to the mounting hole axis A1.

For example, the chain guide 44 is connected to the second inner link end 42B of the inner link 42 so as to be rotatable about the second inner link axis Y2. The first inner link axis Y1 and the second inner link axis Y2 are arranged parallel to the mounting hole axis A1 in the assembled state of the front derailleur 30.

The inner link 42 includes, for example, a first inner link shaft member 42X and a second inner link shaft member 42Y. The first inner link shaft member 42X connects the first inner link end 42A to the base member 32 such that the first inner link end 42A is rotatable about the first inner link axis Y1. The axis of the first inner link shaft member 42X coincides with the first inner link axis Y1. The second inner link shaft member 42Y connects the second inner link end 42B to the chain guide 44 such that the second inner link end 42B can rotate about the second inner link axle center Y2. The axis of the second inner link shaft member 42Y coincides with the second inner link axis Y2. The inner link 42 may not include the first inner link shaft member 42X and the second inner link shaft member 42Y. The first inner link end 42A can be directly connected to the base member 32 and the second inner link end 42B can be directly connected to the chain guide 44.

The chain guide 44 is rotatably connected to the second inner link end 42B of the inner link 42 about the second inner link axis Y2, and rotatably connected to the second outer link end 38B of the outer link 38 about the second outer link axis X2, so as to be movable between the retracted position PG1 and the extended position PG2 with respect to the base member 32. When the chain guide 44 moves from the retracted position PG1 to the extended position PG2, the first outer link end 38A rotates about the first outer link axis X1 in the second outer link rotation direction PL 2. When the chain guide 44 moves from the extended position PG2 to the retracted position PG1, the first outer link end 38A rotates about the first outer link axial center X1 in the first outer link rotation direction PL 1.

For example, the chain guide 44 includes a laterally outer guide plate 44A and a laterally inner guide plate 44B. In the installed state, the laterally outer guide plate 44A is located farther from the frame 12 of the human-powered vehicle 10 than the laterally inner guide plate 44B. For example, a chain receiving groove 44C is formed between the lateral outer guide plates 44A and the lateral inner guide plates 44B. When the chain guide 44 is in the retracted position PG1, the chain receiving groove 44C overlaps at least a portion of the first sprocket 16A of the front sprocket 16 as viewed in a direction parallel to the mounting hole axis A1. When the chain guide 44 is located at the extended position PG2, the chain receiving groove 44C overlaps at least a portion of the second sprocket 16B of the front sprocket 16 when viewed in a direction parallel to the mounting hole axis A1.

With the chain guide 44 in the retracted position PG1, the drive chain 18 engages with the first sprocket 16A. When the chain guide 44 is in the extended position PG2, the drive chain 18 engages with the second sprocket 16B. Front derailleur 30 changes the sprocket engaged by drive chain 18 by movement of chain guide 44 relative to base member 32 between a retracted position PG1 and an extended position PG 2. That is, when the chain guide 44 is moved from the retracted position PG1 to the extended position PG2, the sprocket engaged by the drive chain 18 is changed from the first sprocket 16A to the second sprocket 16B by the lateral inner guide plate 44B. When the chain guide 44 is moved from the extended position PG2 to the retracted position PG1, the sprocket engaged with the drive chain 18 is changed from the second sprocket 16B to the first sprocket 16A by the lateral outer guide plate 44A.

As seen in FIG. 4, the front derailleur 30 is further provided with a support bolt 46. For example, the support bolts 46 are provided to the base member 32. For example, the support bolt 46 is configured to adjust the tilt of the front derailleur 30 relative to the frame 12 of the manually driven vehicle 10. A support plate 46A is disposed between the support bolt 46 and the frame 12 of the manually driven vehicle 10. The base member 32 is formed with, for example, a support bolt hole 46B. The support bolt hole 46B includes, for example, a through hole. The support bolt 46 is configured to be screwed with the support bolt hole 46B. The support plate 46A may be omitted as desired.

The support bolts 46 are configured such that the support bolts 46 are screwed into the support bolt holes 46B, whereby the front ends of the support bolts 46 press the frame 12 of the manually driven vehicle 10. The frame 12 is pressed by the front end of the support bolt 46, and the main body portion 36 of the base member 32 is elastically deformed. The main body portion 36 of the base member 32 is elastically deformed such that the inclination of the front derailleur 30 relative to the frame 12 of the manually driven vehicle 10 is changed. Thus, by threading the support bolt 46 into the base member 32, the tilt of the front derailleur 30 relative to the frame 12 of the manually driven vehicle 10 is adjusted. Since the base member 32 is supported to the frame 12 by the support bolts 46, vibration of the front derailleur 30 relative to the frame 12 of the manually driven vehicle 10 is suppressed, and the rigidity of the front derailleur 30 is improved.

As shown in fig. 2 and 5, the outer link 38 has a first outer link end 38A, a second outer link end 38B, and an opening 48. For example, the lateral direction D2 is defined as a direction from one of the lateral outer guide plate 44A and the lateral inner guide plate 44B toward the other of the lateral outer guide plate 44A and the lateral inner guide plate 44B in the mounted state. The lateral direction D2 corresponds to a direction toward a side of the manually driven vehicle 10, for example. For example, the opening 48 of the outer link 38 faces the lateral direction D2.

The opening 48 is provided in the outer link outer surface 38C of the outer link 38. The outer link outer surface 38C is a surface of the outer link 38 facing away from the frame 12 of the manually driven vehicle 10 in the mounted state. The opening 48 includes, for example, a through hole that penetrates the outer link 38 in the lateral direction D2. The opening 48 is formed in the outer link outer surface 38C so that the base member 32 can be seen through the opening 48 when the outer link 38 is viewed from the viewing direction D1. The viewing direction D1 is a direction from the outer link 38 toward the base member 32. For example, the support bolt 46 is arranged so as to be visible through the opening 48 of the outer link 38 when seen from the viewing direction D1. For example, the outer link 38 has a peripheral portion 50. For example, the peripheral portion 50 defines the opening 48.

As shown in fig. 6, for example, the opening 48 of the outer link 38 and the support bolt 46 are provided such that the tool T1 for rotating the support bolt 46 can contact the support bolt 46 through the opening 48 of the outer link 38. As long as the tool T1 for rotating the support bolt 46 can contact the support bolt 46 through the opening 48 of the outer link 38, the shape of the opening 48 can be arbitrarily changed. The tool T1 may be a tool different from the tool T1 for rotating the support bolt 46 as long as the tool is a tool for the base member 32. For example, the tool T1 may be a cleaning tool for removing mud, dust, or the like adhering to the base member 32.

As shown in fig. 2, the inner wire fixing structure 52 is provided to one of the inner link 42 and the outer link 38 without via the other links. For example, in the case where the inner wire fixing structure 52 is provided to the inner link 42, the inner link 42 provided with the inner wire fixing structure 52 is constituted by one member. For example, in the case where the inner wire fixing structure 52 is provided to the outer link 38, the outer link 38 provided with the inner wire fixing structure 52 is constituted by one member. The inner wire fixing structure 52 of the present embodiment is provided to the outer link 38. The inner wire fixing structure 52 may be provided to one of the inner link 42 and the outer link 38 via another link.

The inner wire fixing structure 52 is configured to fix the inner wire 20A of the bowden cable 20. The inner wire fixing structure 52 is configured to be able to adjust the tension of the inner wire 20A in a state where the inner wire 20A of the bowden wire 20 has been fixed. The "fixed" in this specification allows movement of the inner wire 20A to maintain the degree of function of the front derailleur 30 in the case of using the manually driven vehicle 10. The movement of the inner wire 20A to maintain the function of the front derailleur 30 includes a minute movement caused by the extension of the inner wire 20A, a minute movement caused by the sliding of the inner wire 20A, and the like, for example.

In the present embodiment, the inner wire fixing structure 52 is provided at the first outer link end 38A of the outer link 38. The inner wire 20A is secured by the inner wire securing structure 52 such that the inner wire 20A is mounted to the first outer link end 38A. The rotation of the first outer link end 38A in the first outer link rotation direction PL1 by the outer link urging member 36B is suppressed by the inner wire 20A.

The inner wire fixation structure 52 includes a cable fastener 54 and a cable adjuster 56. The cable fastener 54 is configured to switch between a cable fixing state and a cable releasing state. During the cable fixing state of the cable fastener 54, the cable fastener 54 is configured to fix the inner wire 20A of the bowden cable 20. During the cable fastener 54 is in the cable-released state, the cable fastener 54 is configured to release the inner wire 20A of the bowden cable 20. The cable adjuster 56 is configured to move the inner wire 20A of the bowden cable 20. The inner wire fixing structure 52 is configured to rotate with respect to one of the inner link 42 and the outer link 38 with the cable fastener 54 in a cable-fixed state. In the present embodiment, the inner wire fixing structure 52 is configured to rotate relative to the outer link 38 during the cable fixing state of the cable fastener 54.

As shown in fig. 7 and 8, the inner wire fixing structure 52 is configured to move between the first attachment position and the second attachment position with respect to the outer link 38 around the attachment hole axis A1. The inner wire fixing structure 52 is configured to rotate around the mounting hole axis A1 in the first cable rotation direction PC1 and the second cable rotation direction PC 2. The first cable rotation direction PC1 is a rotation direction of the inner wire fixing structure 52 from the first installation position toward the second installation position. The second cable rotation direction PC2 is a rotation direction of the inner wire fixing structure 52 from the second installation position toward the first installation position. The second cable rotation direction PC2 is a rotation direction opposite to the first cable rotation direction PC 1. The rotation angle of the inner wire fixing structure 52 about the mounting hole axis A1 from the first mounting position to the second mounting position can be arbitrarily set according to the length of the inner wire 20A to be tension-adjusted. In one example, when the inner wire fixing structure 52 is moved from the first mounting position to the second mounting position, the inner wire fixing structure 52 is set to rotate 48 degrees about the mounting Kong Zhouxin A1.

The cable fastener 54 shown in fig. 3 is in a cable-released state. For example, the inner wire fixing structure 52 is rotatably attached to the attachment hole 40 of the outer link 38 about the attachment Kong Zhouxin A1. For example, the cable fastener 54 includes a cable fixing bolt 58. For example, the cable fixing bolt 58 has a cable fixing head 58A and a cable fixing shaft 58B. For example, the cable fastener 54 includes a cable fixing plate 60. For example, the cable fixing plate 60 has plate holes 60A. For example, the plate hole 60A is through to allow the cable fixing shaft 58B to pass through in the assembled state of the front derailleur 30.

For example, the cable fixing shaft 58B of the cable fixing bolt 58 is mounted to the actuator hole 62B of the cable actuator 62 in such a manner that the inner wire 20A of the bowden cable 20 is fixed between the cable fixing head 58A of the cable fixing bolt 58 and the cable actuator 62 in the mounting hole axial direction D3. For example, the cable fixing shaft 58B of the cable fixing bolt 58 is mounted to the actuator hole 62B of the cable actuator 62 in such a manner that the inner wire 20A of the bowden cable 20 is fixed between the cable fixing plate 60 of the cable fastener 54 and the cable actuator 62 in the mounting hole axial direction D3.

For example, the cable adjuster 56 includes a cable actuator 62. For example, the cable adjuster 56 includes a cable actuator 62 and an actuator fixing bolt 64. The cable actuator 62 is configured to cover at least a portion of the first outer link end 38A. For example, the cable actuator 62 is mounted to the mounting hole 40 of the outer link 38. The cable actuator 62 includes an actuator mounting portion 62A. The actuator mounting portion 62A is formed in a cylindrical shape. The actuator mounting portion 62A is disposed in the mounting hole 40 of the outer link 38 such that the cable actuator 62 can rotate about the mount Kong Zhouxin A1 relative to the outer link 38.

For example, the cable actuator 62 has an actuator hole 62B. The actuator hole 62B is formed in the actuator mounting portion 62A so as to penetrate along the mounting hole axial direction D3. For example, the mounting hole axial direction D3 is a direction about the mounting hole axis A1 in the assembled state of the front derailleur 30. The mounting hole axial direction D3 is, for example, a direction parallel to the mounting hole axis A1. The cable fastener 54 is switched from the cable-released state to the cable-fixed state by the cable-fixing bolt 58 being screwed to the actuator hole 62B. Since the cable fixing bolt 58 is screwed into the actuator hole 62B in the cable fixing state, the cable fastener 54 is configured to rotate integrally with the cable actuator 62 with respect to the outer link 38.

As shown in fig. 2 and 9, for example, the cable actuator 62 has a cable guide groove portion 66. The cable guide groove 66 is recessed from the surface of the cable actuator 62 in a direction parallel to the mounting hole axis A1. The cable guide groove portion 66 is formed around the actuator hole 62B at least a part of the periphery of the actuator hole 62B. For example, the cable guide groove portion 66 is configured to receive the inner wire 20A of the bowden cable 20 in the assembled state of the front derailleur 30. The inner wire 20A of the bowden cable 20 is disposed in the inner wire passage 74 from the bowden cable mounting portion 36A via the cable guide slot portion 66 in the assembled state of the front derailleur 30.

For example, the cable actuator 62 has at least one cable fixing tab 68. The cable fixing protrusion 68 is configured to protrude from the surface of the cable actuator 62 in a direction parallel to the mounting hole axis A1. In the present embodiment, the at least one cable fixing protrusion 68 includes three cable fixing protrusions 68. For example, at least one cable fixing protrusion 68 is provided to the cable guide groove 66. The cable fixing protrusion 68 is formed such that a front end portion thereof perpendicularly intersects with a direction in which the cable guide groove 66 extends. Therefore, in the cable-fixed state, the at least one cable-fixing protrusion 68 is easily brought into contact with the inner wire 20A received by the cable-guiding groove 66.

For example, the at least one cable fixing tab 68 is configured to facilitate fixing of the inner wire 20A of the bowden cable 20 between the cable fastener 54 and the cable regulator 56. For example, the at least one cable fixing protrusion 68 is configured to facilitate fixing of the inner wire 20A of the bowden cable 20 between the cable fixing plate 60 and the cable regulator 56. Since the at least one cable fixing protrusion 68 presses the inner wire 20A toward the cable fixing plate 60, the inner wire 20A is facilitated to be fixed between the cable fixing plate 60 and the cable regulator 56.

As shown in fig. 3, for example, the cable actuator 62 has an actuator hole screw portion 62C. For example, an actuator hole screw portion 62C is formed in the actuator hole 62B. The actuator bore threaded portion 62C has a first internal threaded portion. For example, the cable fixing bolt 58 has a cable fixing threaded portion 58C. For example, the cable fixing threaded portion 58C is formed on the cable fixing shaft 58B. The cable fixing threaded portion 58C has a first male threaded portion. For example, the cable fixing screw portion 58C is configured to screw with the actuator hole screw portion 62C. The first male screw portion is configured to be screwed with the first female screw portion, for example. In the present embodiment, the first female screw portion of the actuator hole screw portion 62C and the first male screw portion of the cable fixing screw portion 58C are clockwise screws.

As shown in fig. 3 and 10, for example, the cable adjuster 56 includes an actuator fixing bolt 64. For example, the actuator fixing bolt 64 has an actuator fixing head 64A and an actuator fixing shaft 64B. For example, the actuator fixing head 64A of the actuator fixing bolt 64 contacts the outer link 38 in the assembled state of the front derailleur 30. The cable actuator 62 and the actuator fixing bolt 64 are arranged to sandwich the outer link 38 in the mounting hole axial direction D3 and respectively contact the outer link 38. Since the cable actuator 62 and the actuator fixing bolt 64 are in contact with the outer link 38 so as to sandwich the outer link 38, the inner wire fixing structure 52 is positioned with respect to the outer link 38 in a direction parallel to the mounting hole axis A1.

For example, the actuator fixing shaft 64B of the actuator fixing bolt 64 is mounted to the mounting hole 40 of the outer link 38 and the actuator hole 62B of the cable actuator 62 in the assembled state of the front derailleur 30. The mounting hole 40 of the outer link 38 has, for example, a first mounting hole portion 40A and a second mounting hole portion 40B. The second mounting hole portion 40B is adjacent to the first mounting hole portion 40A in a direction parallel to the mounting hole axis A1. The first mounting hole portion 40A mounts an actuator mounting portion 62A of the cable actuator 62. The second mounting hole portion 40B mounts an actuator fixing shaft 64B of the actuator fixing bolt 64. The diameter of the inner peripheral surface of the second mounting hole portion 40B is smaller than the diameter of the inner peripheral surface of the first mounting hole portion 40A. Since the diameter of the actuator fixing head 64A is larger than the diameter of the inner peripheral surface of the second mounting hole portion 40B, the actuator fixing head 64A can be appropriately brought into contact with the outer link 38 in the mounting hole axial direction D3.

For example, the actuator fixing bolt 64 has an actuator fixing threaded portion 64C. For example, an actuator fixing screw portion 64C is formed at the actuator fixing shaft 64B. The actuator fixing screw portion 64C has a second external screw portion. The actuator bore threaded portion 62C has a second internal threaded portion. The second female screw portion is formed in the actuator hole screw portion 62C so as to be juxtaposed with the first female screw portion in the mounting hole axial direction D3. For example, the actuator fixing screw portion 64C is formed to screw with the actuator hole screw portion 62C. The second male screw portion is configured to be screwed with the second female screw portion, for example. The actuator fixing screw portion 64C is screwed to the actuator hole screw portion 62C from the opposite side of the cable fixing screw portion 58C in the mounting hole axial direction D3.

As shown in fig. 3, for example, the cable fixing shaft 58B and the actuator fixing shaft 64B are disposed apart from each other in the mounting hole axial direction D3 in the assembled state of the front derailleur 30. In summary, the cable fixing shaft 58B and the actuator fixing shaft 64B are screwed to the actuator hole screw portion 62C so as not to contact inside the actuator hole 62B. The length of the cable fixing shaft 58B and the length of the actuator fixing shaft 64B are set such that the cable fixing shaft 58B and the actuator fixing shaft 64B do not contact inside the actuator hole 62B. Therefore, the first female screw portion and the first male screw portion can be screwed reliably, and the second female screw portion and the second male screw portion can also be screwed reliably.

As shown in fig. 11 and 12, the cable regulator 56 is rotatably mounted to the mounting hole 40 of the outer link 38 about the mounting Kong Zhouxin A1. The inner wire fixation structure 52 is configured to rotate about the mounting hole axis A1 relative to the outer link 38 by rotation of the cable adjuster 56 about the mounting Kong Zhouxin A1. The inner wire 20A of the bowden cable 20 is configured to move about the mounting hole axis A1 by the rotation of the inner wire fixing structure 52 about the mounting hole axis A1 relative to the outer link 38.

For example, the cable adjuster 56 includes an actuator adjuster 70. For example, the actuator adjuster 70 is configured to adjust the rotation of the inner wire fixation structure 52 relative to the outer link 38. For example, the cable actuator 62 has an adjustment aperture 72. The adjustment hole 72 has an adjustment hole axis A2. The adjustment hole 72 is a through hole that opens so that the adjustment hole axis A2 intersects the outer link 38 when viewed from a direction parallel to the mounting hole axis A1. For example, the adjustment aperture 72 is configured to receive the actuator regulator 70.

For example, the actuator adjuster 70 has an actuator adjustment screw portion 70A. The actuator adjustment screw 70A has a third male screw. For example, the cable adjuster 56 has an adjustment hole threaded portion 72A. For example, an adjustment hole screw portion 72A is formed in the adjustment hole 72. The adjustment hole screw portion 72A has a third female screw portion. For example, the actuator adjustment screw 70A is configured to screw with the adjustment hole screw 72A. For example, the third male screw portion is configured to be screwed with the third female screw portion. The actuator adjustment screw portion 70A is screwed with the adjustment hole screw portion 72A in a direction parallel to the adjustment hole axis A2 so as to face the outer link 38 from the cable adjuster 56.

By screwing the actuator regulator 70 into the adjustment hole screw portion 72A, the actuator regulator 70 is moved toward the outer link 38. The outer link 38 includes a contact surface 38Z with which the front end portion of the actuator regulator 70 contacts. The contact surface 38Z forms a cam surface. When the actuator regulator 70 is screwed into the adjustment hole screw portion 72A, the protruding amount of the actuator regulator 70 from the cable regulator 56 increases, and therefore, the tip end portion of the actuator regulator 70 moves on the contact surface 38Z. In the present embodiment, the contact surface 38Z is formed such that the distance between the cable adjuster 56 and the outer link 38 on the adjustment hole axis A2 increases as the inner wire fixing structure 52 moves from the first mounting position to the second mounting position.

By further screwing the actuator regulator 70 of fig. 12 into the adjustment hole screw portion 72A, the protruding amount of the actuator regulator 70 from the cable regulator 56 becomes large. As the protruding amount of the actuator regulator 70 from the cable regulator 56 becomes larger, the front end portion of the actuator regulator 70 moves on the contact surface 38Z in the direction corresponding to the second mounting position. Since the actuator regulator 70 moves in the direction corresponding to the second mounting position, the cable regulator 56 moves around the mounting hole axis A1 in the first cable rotation direction PC 1. Accordingly, since the cable adjuster 56 moves in the first cable rotation direction PC1 as the actuator adjuster 70 is screwed into the adjustment hole screw portion 72A, the inner wire fixing structure 52 also moves in the first cable rotation direction PC 1. The inner wire fixing structure 52 is moved around the mounting hole axis A1 in the first cable rotation direction PC1, whereby the inner wire fixing structure 52 is changed from the state of fig. 12 to the state of fig. 11. Since the tip end portion of the actuator regulator 70 is in contact with the contact surface 38Z, rotation of the inner wire fixing structure 52 about the mounting hole axis A1 is suppressed in a state where no external force is applied.

For example, the cable adjuster 56 may include an adjustment hole extension member 70X having an extension adjustment hole 72X. The extension adjustment hole 72X is a through hole whose axis coincides with the adjustment hole axis A2. For example, the extension adjustment hole 72X is configured to receive the actuator regulator 70. The extension adjustment hole 72X has an extension adjustment hole screw portion 72Y. The extension adjustment hole screw portion 72Y has an extension female screw portion. For example, the actuator adjustment screw 70A is configured to screw with the extension adjustment hole screw 72Y. The third external thread portion is screwed with the extended internal thread portion. By adjusting the hole extension member 70X, the third male screw portion of the actuator adjustment screw portion 70A is screwed with the third female screw portion and the extension female screw portion. Even in the case where the cable actuator 62 is thin in the direction parallel to the adjustment Kong Zhouxin A2, the actuator regulator 70 can be stably attached to the cable actuator 62 by the adjustment hole extension member 70X.

As shown in FIG. 2, the front derailleur 30 is provided with an inner wire passage 74. The inner wire passage 74 is configured to guide the inner wire 20A of the bowden cable 20. In the present embodiment, the inner wire passage 74 guides the inner wire 20A of the bowden cable 20 from the rear to the front of the manually driven vehicle 10. An inner wire passage 74 is provided in the outer link 38. For example, the inner wire passage 74 is provided at least one of the first outer link end 38A and the second outer link end 38B. For example, the inner wire passage 74 is coaxial with at least one of the first outer link axial center X1 and the second outer link axial center X2. For example, the inner wire passage 74 is provided at the first outer link end 38A. For example, the inner wire passage 74 is coaxial with the first outer link axial center X1. In the present embodiment, the inner wire passage 74 is provided in the first outer link shaft member 38X. The outer link 38 has, for example, an inner wire groove 74A that guides the inner wire 20A from the cable fastener 54 to the inner wire passage 74.

As shown in fig. 5 and 10, the inner wire passage 74 includes, for example, a first passage 74X provided in the base member 32 and a second passage 74Y provided in the outer link 38. The first passage 74X and the second passage 74Y are through holes coaxial with the first outer link axial center X1. The inner wire passage 74 includes, for example, a third passage 74Z provided in the first outer link shaft member 38X. The third passage 74Z is a through hole coaxial with the first outer link axial center X1. The inner wire passage 74 guides the inner wire 20A such that the inner wire 20A passes through the first passage 74X, the second passage 74Y, and the third passage 74Z. An end of the inner wire 20A guided by the inner wire passage 74 is fitted with an end cap 20C.

As seen in FIG. 5, the front derailleur 30 is provided with a base member 32, an outer link 38, a chain guide 44 and a position adjustment structure 76. The front derailleur 30 is provided with a base member 32, an inner link 42, an outer link 38, a chain guide 44 and a position adjustment structure 76. The position adjustment structure 76 is provided on the outer link 38.

As shown in fig. 13 and 14, the position adjustment structure 76 is configured to be able to selectively adjust at least one of the extended position PG2 and the retracted position PG1 of the chain guide 44. The position adjustment structure 76 is provided on the outer link outer side surface 38C of the outer link 38 so that a tool T2 for rotating the position adjustment structure 76 can come into contact with the position adjustment structure 76 from the lateral direction D2 of the manually driven vehicle 10. The tool T2 for rotating the position adjustment structure 76 is a tool for adjusting the position of the chain guide 44. The position adjustment structure 76 includes at least one of an extended position adjustment bolt 78 and a retracted position adjustment bolt 80. In the present embodiment, the position adjustment structure 76 includes both an extended position adjustment bolt 78 and a retracted position adjustment bolt 80. For example, an extended position adjustment bolt 78 and a retracted position adjustment bolt 80 are provided to the peripheral portion 50.

The extended position adjustment bolt 78 is configured to be provided to the outer link 38 and selectively contacts the base member 32 in order to selectively adjust the extended position PG2 of the chain guide 44 associated with the base member 32. The retracted position adjusting bolt 80 is configured to be provided to the outer link 38 and selectively contact the base member 32 in order to selectively adjust the retracted position PG1 of the chain guide 44 associated with the base member 32. The extension position adjustment bolt 78 and the retraction position adjustment bolt 80 are configured to protrude from the outer link inner side surface 38D of the outer link 38 in the assembled state of the front derailleur 30. The outer link inner side surface 38D is a surface of the outer link 38 located on the opposite side of the outer link outer side surface 38C. The outer link inner side 38D is configured to face the base member 32 in an assembled state of the front derailleur 30.

For example, the extended position adjustment bolt 78 has a first tool engagement surface 78A. For example, the first tool engagement surface 78A faces away from the frame 12 of the manually driven vehicle 10 in the installed state. For example, the retracted position adjustment bolt 80 has a second tool engagement surface 80A. For example, the second tool engagement surface 80A faces away from the frame 12 of the manually driven vehicle 10 in the mounted state. The first tool engagement surface 78A and the second tool engagement surface 80A face in the same direction as the outer link outer side surface 38C. The first tool engagement surface 78A and the second tool engagement surface 80A are configured to engage a tool T2 for rotating the position adjustment structure 76. The tool T2, which is identical to the second tool engagement surface 80A, is engaged with the first tool engagement surface 78A.

For example, the position adjustment structure 76 includes at least one of an extended position adjustment aperture 82 and a retracted position adjustment aperture 84. In this embodiment, the position adjustment structure 76 includes both an extended position adjustment aperture 82 and a retracted position adjustment aperture 84. For example, the extended position adjustment hole 82 is configured to be provided in the outer link 38 and to receive the extended position adjustment bolt 78. For example, the retracted position adjustment hole 84 is configured to be provided in the outer link 38 and to receive the retracted position adjustment bolt 80.

For example, the extension position adjustment hole 82 has an extension hole axis B1. For example, the retracted position adjusting hole 84 has a retracted hole axis B2. For example, the first outer link axis X1 is provided between the extension hole axis B1 and the retraction hole axis B2. In the assembled state of the front derailleur 30, as seen in FIG. 13, the first outer link axle center X1 is disposed between the extension hole axle center B1 and the retraction hole axle center B2 when viewed from a direction parallel to the first outer link axle center X1. For example, an extended position adjustment hole 82 and a retracted position adjustment hole 84 are provided in the peripheral portion 50. An extended position adjustment hole 82 and a retracted position adjustment hole 84 are formed in the peripheral portion 50 in the outer link 38.

For example, the position adjustment structure 76 includes an extended position abutment surface 86 and a retracted position abutment surface 88. For example, the extended position abutment surface 86 is configured to be provided on the base member 32 and to be in contact with the extended position adjustment bolt 78. For example, the retracted position abutment surface 88 is configured to be provided on the base member 32 and to be in contact with the retracted position adjusting bolt 80. The first outer link axial center X1 is disposed between the extended position abutment surface 86 and the retracted position abutment surface 88. In the assembled state of the front derailleur 30, the first outer link axle center X1 is disposed between the extended position abutment surface 86 and the retracted position abutment surface 88 as seen in the transverse direction D2.

As shown in fig. 13, with the chain guide 44 of the base member 32 in the extended position PG2, the extended position abutment surface 86 contacts the extended position adjustment bolt 78. As the extension position adjustment bolt 78 is screwed into the extension position adjustment hole 82, the extension position adjustment bolt 78 gradually protrudes from the outer link inner side surface 38D of the outer link 38. When the first outer link end 38A rotates in the second outer link rotation direction PL2 about the first outer link axial center X1 as the protruding amount of the protruding position adjustment bolt 78 becomes larger, the rotation amount of the first outer link end 38A becomes smaller until the protruding position adjustment bolt 78 comes into contact with the protruding position abutment surface 86. By the contact of the extended position adjusting bolt 78 with the extended position abutting surface 86, the rotation of the first outer link end 38A about the first outer link axial center X1 in the second outer link rotational direction PL2 is suppressed. Accordingly, the extended position PG2 of the chain guide 44 can be selectively adjusted in such a manner that the frame 12 of the manually driven vehicle 10 is accessed by screwing the extended position adjustment bolt 78 into the extended position adjustment hole 82.

As shown in fig. 14, with the chain guide 44 of the base member 32 in the retracted position PG1, the retracted position abutment surface 88 contacts the retracted position adjusting bolt 80. As the retracted position adjusting bolt 80 is screwed into the retracted position adjusting hole 84, the retracted position adjusting bolt 80 gradually protrudes from the outer link inner side surface 38D of the outer link 38. When the first outer link end 38A rotates about the first outer link axial center X1 in the first outer link rotational direction PL1 as the protruding amount of the retracted position adjusting bolt 80 becomes larger, the rotational amount of the first outer link end 38A becomes smaller until the retracted position adjusting bolt 80 comes into contact with the retracted position abutment surface 88. By the contact of the retracted position adjusting bolt 80 with the retracted position abutment surface 88, the rotation of the first outer link end 38A about the first outer link axial center X1 in the first outer link rotational direction PL1 is suppressed. Thus, the retracted position PG1 of the chain guide 44 can be selectively adjusted in such a manner that the retracted position adjusting bolt 80 is screwed into the retracted position adjusting hole 84 so as to be away from the frame 12 of the human-powered vehicle 10.

As shown in fig. 1 and 5, for example, the chain driving direction D4 is defined as a direction in which the drive chain 18 moves in the chain receiving groove 44C at the time of pedaling. The chain drive direction D4 corresponds to, for example, a direction from the rear toward the front of the manually driven vehicle 10. The position adjusting mechanism 76 is disposed downstream of the opening 48 of the outer link 38, for example, with respect to the chain drive direction D4. For example, the extension position adjusting bolt 78 and the retraction position adjusting bolt 80 are disposed downstream of the opening portion 48 of the outer link 38 with respect to the chain driving direction D4.

With reference to fig. 15 to 17, a method of adjusting the front derailleur 30 based on the inner wire fixing structure 52 will be explained. The adjustment method of the front derailleur 30 based on the inner wire fixing structure 52 is performed in the mounted state. During the cable securing state of the cable fastener 54, the inner wire securing structure 52 rotates relative to the outer link 38, whereby the position of the chain guide 44 relative to the frame 12 of the human-powered vehicle 10 is adjusted. The adjustment method includes a first step, a second step, and a third step.

The first step is a step of fixing the inner wire 20A to the inner wire fixing structure 52. In the first step, as in an example of the cable released state shown in fig. 15, for example, the cable fastener 54 is detached. In the first process, the cable fastener 54 is in a cable-released state, and the inner wire fixing structure 52 is disposed at the first installation position. With the cable fastener 54 in the cable-released state, the chain guide 44 is moved to the retracted position PG1 by the urging force of the outer link urging member 36B. The inner wire 20A is disposed in the cable guide groove portion 66 so as to pass over the at least one cable fixing protrusion portion 68, and the cable fastener 54 is switched from the cable released state to the cable fixed state, whereby the inner wire 20A is fixed between the cable fixing plate 60 and the cable actuator 62.

The second process is a process in which the chain guide 44 is moved to the extended position PG2. In the second step, as shown in fig. 16, the shift operating portion is operated to move the chain guide 44 to the extended position PG2.

The third step is a step of adjusting the position of the chain guide 44 with respect to the frame 12 of the manually driven vehicle 10. In the third step, the actuator regulator 70 is screwed into the adjustment hole 72 of the cable regulator 56, whereby the inner wire fixing structure 52 is rotated in the first cable rotation direction PC1, and the state of fig. 16 is changed to the state of fig. 17. The inner wire 20A rotates around the mounting hole axis A1 in the first cable rotation direction PC1 by the inner wire fixing structure 52 rotating in the first cable rotation direction PC1, and thus the tension of the inner wire 20A becomes strong. Since the tension of the inner wire 20A becomes strong, the first outer link end 38A rotates around the first outer link axial center X1 in the second outer link rotation direction PL 2. The first outer link end 38A rotates about the first outer link axis X1 in the second outer link rotation direction PL2, whereby the second outer link end 38B moves in the lateral direction D2 away from the frame 12 of the manually driven vehicle 10. Since the second outer link end 38B moves in the transverse direction D2 away from the frame 12 of the human powered vehicle 10, the chain guide 44 also moves in the transverse direction D2 away from the frame 12 of the human powered vehicle 10. As described above, since the chain guide 44 moves in the lateral direction D2, the position of the chain guide 44 is adjusted according to the positional relationship of the lateral inner guide plate 44B and the drive chain 18.

As shown in fig. 18, the adjustment method of the front derailleur 30 based on the inner wire fixing structure 52 uses a first clamp J1, for example. The first clamp J1 is disposed between the cable actuator 62 and the outer link 38 to restrain rotation of the inner wire fixing structure 52 in a state where the inner wire fixing structure 52 is in the first mounting position. The first clamp J1 is mounted to the front derailleur 30 in a first step of a method of adjusting the front derailleur 30 based on the wire fixing structure 52. In the steps subsequent to the second step of the adjustment method of the front derailleur 30 based on the inner wire fixing structure 52, the first clamp J1 is removed from the front derailleur 30. Since the rotation of the inner wire fixing structure 52 in the first process in the first cable rotation direction PC1 is suppressed by the first clamp J1, when the first male screw portion of the cable fixing screw portion 58C of the cable fixing bolt 58 is a positive screw, the fixing of the inner wire 20A in the first process described above is easy. The first clamp J1 may be omitted as needed.

In the case where the first clamp J1 is omitted, the inner wire fixing structure 52 may be configured such that the cable fastener 54 is switched from the cable-releasing state to the cable-fixing state by screwing the cable fixing bolt 58 into the actuator hole 62B in the second cable rotation direction PC 2. That is, the first male screw portion of the cable fixing screw portion 58C of the cable fixing bolt 58 may be constituted by a reverse screw. In the case where the first male screw portion of the cable fixing screw portion 58C of the cable fixing bolt 58 is a reverse screw, even if the cable fixing bolt 58 is screwed into the actuator hole 62B in the second cable rotation direction PC2, the rotation of the cable actuator 62 in the first cable rotation direction PC1 can be suppressed, and therefore, the fixing of the inner wire 20A in the first step described above is easy.

The adjustment method of the front derailleur 30 based on the inner wire fixing structure 52 uses the second clamp J2, for example. When the internal wire 20A is not disposed in the internal wire passage 74, the second clamp J2 is disposed in the internal wire passage 74 so as to penetrate the internal wire passage 74. The second clamp J2 can prevent the unused internal passage 74 from being clogged with mud or the like. In the case where the first clamp J1 is disposed between the cable actuator 62 and the outer link 38, the second clamp J2 may be integrally formed with the first clamp J1 in order to inhibit the first clamp J1 from falling off the front derailleur 30. The second clamp J2 may also be omitted, as desired.

< Second embodiment >

The front derailleur 30 of the second embodiment will be explained with reference to fig. 19 and 20. The front derailleur 30 of the second embodiment is identical to the front derailleur 30 of the first embodiment, except that the inner wire fixing structure 52 does not include the cable adjuster 56, the opening 48 of the outer link 38 is different in size, and the front derailleur 30 does not include the inner wire passage 74. Therefore, the same reference numerals as those of the first embodiment are given to the structures common to the first embodiment, and the duplicate description is omitted.

The inner wire fixing structure 52 of the present embodiment does not include the cable adjuster 56. The cable fastener 90 of the inner wire fixing structure 52 of the present embodiment includes, for example, a cable fixing bolt 92. The cable fastener 90 includes, for example, a cable fixing plate 94. The plate holes of the cable fixing plate 94 are, for example, through holes for the cable fixing transmission shaft of the cable fixing bolt 92 to pass through in the assembled state of the front derailleur 30.

In the present embodiment, the cable fixing bolt 92 is screwed into the mounting hole 40 of the outer link 38, so that the cable fixing bolt 92 is screwed into the mounting hole 40 of the outer link 38. In the present embodiment, the inner wire 20A of the bowden cable 20 is fixed between the cable fixing head of the cable fixing bolt 92 and the outer link 38 in the mounting hole axial direction D3. In the present embodiment, the inner wire 20A of the bowden cable 20 is fixed between the cable fixing plate 94 of the cable fastener 90 and the outer link 38 in the mounting hole axial direction D3.

In the front derailleur 30 of the present embodiment, the size of the opening portion 48 of the outer link 38 is different from the size of the opening portion 48 of the outer link 38 of the first embodiment. In the present embodiment, the length of the opening 48 in the direction perpendicular to the mounting hole axial direction D3 is shorter than the length of the opening 48 in the direction perpendicular to the mounting hole axial direction D3 in the first embodiment, when viewed from the viewing angle direction D1. The size of the opening 48 of the outer link 38 of the present embodiment may be arbitrarily different from the size of the opening 48 of the outer link 38 of the first embodiment as long as the support bolt 46 is visible through the opening 48 of the outer link 38 when viewed from the viewing angle direction D1.

The front derailleur 30 of the present embodiment does not have the inner wire passage 74. In the present embodiment, the end of the inner wire 20A fixed to the inner wire fixing structure 52 is attached with the end cap 20C.

< Modification >

The description of the embodiments is an example of the manner in which a front derailleur for a human-powered vehicle in accordance with the present disclosure may take place, and is not intended to be limiting of the manner in which it may take place. For example, the front derailleur for a manually driven vehicle according to the present disclosure may be configured by combining at least two modifications of the following embodiments, which are not contradictory to each other. In the following modification, the same reference numerals as those in the embodiment are given to the portions common to the embodiment, and the description thereof is omitted.

The cable fastener 54 may not include the cable fixing plate 60. In the case where the cable fastener 54 does not include the cable fixing plate 60, the inner wire 20A may be fixed between the cable fixing bolt 58 and the cable actuator 62.

The at least one cable fixing protrusion 68 may include only one cable fixing protrusion 68, two cable fixing protrusions 68, or four or more cable fixing protrusions 68. The number of the at least one cable fixing protrusion 68 can be set, for example, according to the length of the cable guide groove portion 66, the diameter of the mounting hole 40, and the like.

The inner wire passage 74 may be provided at a location other than the first outer link shaft member 38X. For example, the inner wire fixing structure 52 may be provided to at least one of the second outer link shaft member 38Y, the first inner link shaft member 42X, and the second inner link shaft member 42Y in addition to the first outer link shaft member 38X. Alternatively, the inner wire fixing structure 52 may be provided on the outer link 38 so as not to be coaxial with either of the first outer link axis X1 and the second outer link axis X2. In short, the outer link 38 may be provided with a through hole for guiding the inner wire 20A appropriately as the inner wire passage 74.

The position adjustment structure 76 may include only any one of the extended position adjustment bolt 78 and the retracted position adjustment bolt 80. In the case where the position adjustment structure 76 includes only the extended position adjustment bolt 78, since at least the extended position PG2 of the chain guide 44 can be adjusted, the position of the chain guide 44 can be easily adjusted by the position adjustment structure 76. In the case where the position adjustment structure 76 includes only the retracted position adjustment bolt 80, since at least the retracted position PG1 of the chain guide 44 can be adjusted, the position of the chain guide 44 can be easily adjusted by the position adjustment structure 76.

The position adjustment structure 76 may include only any one of the extended position adjustment hole 82 and the retracted position adjustment hole 84. For example, where the position adjustment structure 76 includes only the extended position adjustment bolt 78, the position adjustment structure 76 may include only the extended position adjustment hole 82. For example, where the position adjustment structure 76 includes only the retracted position adjustment bolt 80, the position adjustment structure 76 may include only the retracted position adjustment hole 84.

The position adjustment structure 76 may be provided on a surface of the outer link 38 other than the outer link outer side surface 38C, as long as it is a surface different from the outer link inner side surface 38D. In the case where the position adjustment structure 76 is provided on a surface different from the outer link inner surface 38D, the tool T2 for operating the position adjustment structure 76 is easier to contact than in the case where the position adjustment structure 76 is provided on a base member or the like.

The arrangement of the position adjustment structure 76 and the opening 48 on the outer link outer surface 38C can be arbitrarily changed. For example, the extension position adjusting bolt 78 and the retraction position adjusting bolt 80 may be disposed upstream of the opening portion 48 of the outer link 38 with respect to the chain driving direction D4. Alternatively, the extension position adjusting bolt 78 and the retraction position adjusting bolt 80 may be disposed upstream of the opening portion 48 of the outer link 38 so as to be aligned in a direction perpendicular to the chain driving direction D4.

In the second embodiment, the front derailleur 30 can be provided with an inner wire passage 74. For example, the inner wire passage 74 is provided to the first outer link shaft member 38X.

In the second embodiment, the outer link 38 may have a cable guide groove portion 66.

In a second embodiment, the outer link 38 may have at least one cable fixing protrusion.
