A retaining member (here an open tail pin) 26 passes through the distal end of the pin 22 on the outside of the washer 25. The holding member 26 prevents the pin 22 from slipping off the pulling portion 21c. A coil spring 28 is disposed between the base portion 21d of the pulling portion 21c and the transmission cable supporting portion 32g. The coil spring 28 applies a force in a direction in which the distance between the base portion 21d and the transmission cable supporting portion 32g is increased. The coil spring 28 is disposed to surround the inner cable 21a. A tube 27 having an outer diameter equal to the inner diameter of the coil spring 28 is attached to the inner cable/. The tube 27 stabilizes the position of the coil spring 28 with respect to the inner cable 2U to prevent the spiral spring 28 from sloshing to make a sound. As shown in Fig. 11, the tensioned portion 31e and the raised portion 31g are coupled by a column 3 11 extending in the vertical direction. The arm 3 1 is continuously pushed so that the cylinder pressing portion 3 1 保持 is kept in contact with the pressed portion 32a of the master cylinder 32. In the present example, as shown in Fig. 6, a torsion spring 34 is provided to extend across the post 3 and the journal member 43 to pull the post 3 li toward the master cylinder 32. 3 The following describes the operation of the brake device. Figures 12 and 13 are diagrams for explaining the operation of the brake device 10 when the chain 128149.doc -20. 200918406 interlocking brake lever 40 is operated. Figure 14 is a diagram showing how the tensioned portion of the arm is moved between the plates 2 =, 21e of the transmission cable 21. Fig. 15 is a view for explaining the operation of the brake device 1 when the current wheel (4) is operated. First, the operation of the brake device 10 when the interlocking brake lever 4 is operated will be described. As described above, in the initial state as shown in FIG. 5 (the state in which the brake operation is not performed), the arm pressing portion 4 2 e of the rotating member 42 is separated by „h; The pressed portion 3 1 c. When the knight starts to operate the interlocking brake lever as shown in Fig. 12, the interlocking brake lever 40 starts to rotate around the journal member 43 toward the grip. Therefore, the rear wheel 煞 = the inner cable 1 ia is pulled by the rotating member 42 to start the rear wheel brake 17. At this time, only the arm pressing portion 42 of the rotating member 42 and the rod side pressed portion 31c of the arm n are in contact with each other; therefore, the arm 31 has not been rotated yet, And the front wheel brake 14 has not yet started to be actuated. After that, when the knight further operates the interlocking brake lever 40 as shown in FIG. 13 and the interlocking brake lever 40 rotates around the journal member 43 toward the gripper, the arm of the rotating member 42 The pressing portion 42 (to the rod-side pressure receiving portion 31 of the arm 31 is applied. Therefore, the arm 3丨 is also rotated around the journal member 43, and the cylinder pressing portion 3u is applied to the pressurized portion of the master cylinder 32 In this way, the front wheel brake _ is initially actuated. At this point the pin 22 is formed along the transmission as shown in FIG. The movement of the holes 21f, 21f of the plates 2ie, 2b allows the tension portion 31e of the arm 31 to move between the plates 21e, 21e of the transmission cable without changing the position of the pulling portion 2U. This prevents the interlocking lever 4 from being smashed. When operated, one of the operation of the interlocking lever 4 is transmitted 128149.doc • 21 · 200918406 to the front wheel brake lever 20. As described above, the distance L1 from the rotational displacement center p of the rotating member 42 to the arm pressing portion 42c. It is shorter than the distance L2 from the center P to the cable attachment portion 42b (see Fig. 10). With this configuration, the pressing force applied to the rod-side pressed portion 31c by the arm pressing portion 42c is increased, allowing The reaction force is received from the rod side pressure receiving portion 31c to rotate the arm 31 without largely rotating (retracting) the rotating member 42. Next, the operation of the brake device 1 when the current rim lever 20 is operated will be described. When the front wheel brake lever 2 is 2 ,, the front wheel brake lever 2 〇 pulls the transmission cable 21, and the pulling portion 21c pulls the tension portion 31e of the arm 31. Therefore, as shown in Fig. 15, the arm 3 1 rotates around the journal member 43, The cylinder pressing portion 3丨a presses the pressed portion 32a of the master cylinder 32 In this manner, the front wheel brake 14 is actuated. At this time, the arm pressing portion 42c of the rotating member 42 and the rod side pressure receiving portion 3 1 c of the arm 31 are spaced apart from each other farther than the initial state. Finally, when the rear wheel brake cable is used The brake device 1 is operated when the inner cable Ua is cut or released from the rotary member 42. Fig. 16 is a view for explaining the brake device 1 operation when the inner cable 11a is released from the rotary member 42. When the kiosk operates the interlocking brake lever 40 in a state where the inner cable is released from the rotary member 42, the interlocking brake lever 40 rotates around the journal member 43 toward the grip 4b as shown in Fig. 16 "the arm of the rotary member 42 at this time" The pressing portion is in contact with the rod side pressure portion 3 lc of the arm 3 1 . Then, the rotating member 42 is rotated around the journal member 46 (reduced 13). Therefore, the arm pressing portion 42c of the suspecting member 42 cannot resist the expansion force of the spring housed in the master cylinder 32 to the rod side pressed portion 3 lc. This prevents the front wheel brake 14 from being actuated when the interlocking lever 40 is in the inner cable " In the state of the towing member 42_, in the above-described brake device 10, the vicinity of the front wheel yoke lock lever 40 is provided. Therefore, the 30-series sigh is placed in the chain of the car and the front wheel: the 蛊& mechanism is set to be separated from each other and the chain brakes..., the car-like line or the like is transmitted to the front-wheel brakes::糸 via- In the case of the singularity of the singularity of the singularity, it is possible that the small one operating force is a transmission loss in the transmission path of the operative force from the continuation of the ;3;; the invention is not limited to the above-mentioned invention Brake modification. For example, in the above description, „ can be varied. Ji M JiAn * 5 The rear wheel brake cable 11 is connected to the joint (four) car (10) via the rotation == 2. However, the rear wheel brake, « can also be directly connected to Fig. 17 is a plan view of a brake device 1A as an example of a device according to this embodiment. In the drawings, the same portions as those described above will be given similar reference numerals and will not be described again. The brake device is said to include a chain of brake levers and a rotating member. The interlocking brake lever 4A includes a sling attachment portion, and the engaging portion Hd of the rear slewing ring U is held by the cable attachment portion. A pulling force from the coil spring UC acts on the inner wheel of the rear wheel brake (4) u (see the figure core chain brake lever 4〇A has a part of the rotation branch hunger. The rotation support part of the hunger is positioned in the attachment part of the armor The rod side of the 31 is subjected to the waste portion... and the rotating member 42A is supported to be rotatable. The rotating member 42A has a rotation supporting portion 42h' and the journal member (e.g., thread) 46 passes through the rotating support portion 42h and the interlocking lever The rotating support portion 40A of 40A. The rotating member 42A also has a cable side supporting portion 42i. The cable side supporting portion 42 is in contact with the inner cable 11a which is subjected to the pulling force of 128149.doc -23-200918406. This rotates the rotating member 42A. (Retraction) Restricted in the direction of the side opposite to the arm 3 1 . Next, the operation of the car device 丨〇A. When the chain brake component 4 is ridiculously carried by the knight to the knight When the grip is rotated, the arm pressing portion 42c of the rotating member 42A presses the rod-side pressure receiving portion 31c of the arm 31, and receives a reaction force from the rod side pressure receiving portion 31e. The inner cable of the rear wheel brake cable 11 i la and Supporting portion 42i contacting side, and the rotation

The member 42A is supported on the side of the rod-side pressure receiving portion 3 1 c to resist the reaction force received by the rotating member 42A from the arm 31. Since the rotating member 42 is supported by the inner cable, the rotating member 42A presses the rod side pressed portion 31c without rotating in the reverse direction (direction E in Fig. 17), and inputs the operating force of the interlocking brake lever 4〇a to Arm 3 1. Next, the operation of the brake device 10A in a state where the inner cable 11a is not connected will be described. In a state where the inner cable 1 la is not connected, the rotating member 42 is allowed to rotate in the direction opposite to the side where the # 3 1 is located. Therefore, as in the example described with reference to Fig. w, when the interlocking brake lever 40A is rotated toward the knight, the arm pressing portion 42c of the rotating member 42 receives a reaction force from the rod side pressed portion 31c of the arm 31, and the rotating member 42A It is impossible to resist the reaction and to rotate in the direction of the rod side dust-receiving portion 31c (direction E in Fig. 17). In this way, it is possible to prevent the only W-wheel brake 14 from being actuated in the case where the interlocking brake lever 4A is operated when the inner cable 11a is not connected. The operation of the brake device 1A has been as described above. In the aforementioned braking device H), one is provided between the rod-side dust-receiving portion 3 1 c of the arm 31 and the f-exciting portion 旋转 of the rotating member 42 (see Fig. 5). This clearance delays the actuation of the front wheel brakes 4 when the interlocking brake lever 4 is operated relative to the start of the operation of the rear wheel brakes 17 128149.doc 24 - 200918406. However, the mechanism for delaying the operation of the front wheel brake 14 is not limited thereto. For example, a force may be applied to the arm 31 in a direction opposite to the direction of movement of f3i to delay the operation of the front wheel brake 14. In the brake device 10, the rotary member 42 is used as a member for inputting the operation force of the interlocking brake lever 40 to the arm 31. However, it is also possible to use the -equalizer as the means for inputting the operation force of the interlocking brake lever 4G to the f 3 i. Fig. 18 is a plan view showing the brake device as an example of the brake device according to this embodiment. Figure 19 is an exploded perspective view of one of the brake devices i〇b, the equalizer, the cymbal and the -arm 61. Figure 2 is a plan view of the equalizer 64 and the arm 61. 21 is an enlarged view of an equalizer 64. Figure 22 is a perspective view of the brake device just as seen from the front - the master cylinder 32B. In these figures, similar parts (4) to those of the aforementioned braking device U) will be referred to by similar reference numerals and will not be described again. In the brakes 奘罟 ^ ^ _ Du,,,, early public set 1 〇Β *, the arm 61 and the master cylinder 32 Β constitute a front wheel brake actuation mechanism 3 〇Β. As shown in the figure, in addition to the equalizer 64 and the arm 61, the brake device further includes a chain brake lever and a propulsion member 65 for the direction opposite to the direction in which the arm 61 moves during the braking operation. Apply force. The arm 61 includes a lever side arm 62 and a cylinder side arm 63 that is movable independently of the lever side arm (four) (see Fig. 19). The arm 63 is rotated by being pressed by the lever side arm 62 or transmitted as described above, thereby applying pressure to the pressed portion of the master cylinder 32B. As shown in Fig. 9 (9), the ::: side arm 63 has a cylinder pressing portion..., a pair of upper and lower rotating supports... 3d, 63d, a pressed portion 63c, and a tensioned portion. The lever 128149.doc -25· 200918406 The side arm 62 has a rotation support portion 63d, a rod side pressure receiving portion, a pressing portion 62a, a stopper core, and a propulsion member attachment 62f as shown in FIG. The pressing portion 仏 of the rod side arm 62 faces the pressed portion 63c' of the cylinder side arm and applies pressure to the pressed portion when the rod-side pressed portion of the rod side arm 62 is pressed by the equalizing cry 64. The rod side arm (four) rainbow side arm 6 3 is caused to rotate together with each other. The rod side pressure receiving portion 62e of the rod side arm 62 is pulled by the advancing member 65 to the equalizer 64 to be in contact with the arm pressing portion Me of the equalizer 64. In this example The inlet member 65 is an elastic member (for example, a spring) having a contraction force and extends between the rod side arm 62 and the master cylinder 32B (see Fig. 18). Specifically, the propulsion member of the rod side arm 62 The attachment portion appears to protrude upward from the core of the rod side pressure receiving portion (see Fig. I9) 'and one end of the propulsion member 附 is attached to the propulsion member attachment 邛 62f. The main cylinder 32B is provided with a propulsion member attachment portion 3 phantom. As shown in Fig. u, in the master cylinder 32B, the propulsion member attachment portion % is formed on the rear wheel brake gauge support portion 32. h - the middle portion extends forward. The middle pusher member attachment portion 32 is - a protrusion # that protrudes upward, and the push member is attached to the push member attachment portion at the other end. The push member "is contrary to The pusher member attachment portion 62f of the lever side arm 62 is pulled in the direction in which the lever side f62 moves in the braking operation. As shown in Figs. 18 and 22, the main red 32B has a positioning portion 32k which is slightly raised forward at the position of the stopper 626 of the lever side arm 62. The stopper 62e is in contact with the positioning portion 32k (see Fig. 18), and the position of the lever side arm α is determined by restricting the rotation of the lever side arm 62 when being pulled by the advancing member 65 128149.doc -26- 200918406

The cylinder pressing portion 63a, the rotation supporting portions 63d, 63d, and the tension portion 63e of the cylinder side arm 63 are respectively attached to the cylinder pressing portion 31a, the rotation supporting portion 31d, and the tension portion 31e of the arm 31 described above. That is, the cylinder pressing portion 63a comes into contact with the pressed portion 32a of the master cylinder 32B, and applies pressure to the pressure receiving portion 32a in response to an operating force of the interlocking brake lever 4B. The rotation support portion 62d of the lever side arm 62 is disposed between the pair of upper and lower rotation support portions 63d, 63d. As shown in Fig. 19, the rotation support portion 63d and the rotation support portion 62d of the lever side arm 62 are provided with the holes 63b, 62b, and the journal member 43 passes through the holes 63b, 62b so that the lever side arm 62 and the cylinder side arm 63 are provided. It is rotatable about the journal member 43. The inner cable 21a of the transmission cable 21 is held by the tension portion 63e, so that the tension portion 6^ is pulled by the inner cable 2U in the figure when the front wheel brake lever 20 is operated, attached to the end of the inner cable 2& The pulling portion 2U is not shown, and only the inner cable (1) is shown as a long double dashed line. As shown in Fig. 20 or Fig. 20, the equalization (four) has a rotary support portion (4) positioned at its center, a gauge attachment portion provided at a position away from the rotary support portion 64a, and is also provided away from the rotary support. Part of the "a-position of the arm pressing portion, and - the raised portion (4). The joint portion Ud of the rear wheel brake cable u is similarly fixed to the aforementioned rotating member by the (four) attachment portion (10) (see Fig. 18).

The opposite wall portion is provided. The arm urging knife is positioned at the rim spanning support portion 64a and the cable attachment The opposite side of the connecting portion 64b is in contact with the rod-side pressed portion of the rod side f62. When the contact portion 64b is a rear wheel brake cable pull, a rotational force about the journal member 46 for Equalizer "on. Therefore, the arm pressing part 62c ⑷ pressed portion to the rod side pressure.

In the present example, as shown in Fig. 21, the center P1 of the connection ridge portion 64f, the center P2 of the rotation support portion 64a, and the line center of the attachment attachment portion P3 are substantially straight (the straight line in Fig. 21). The inner cable mountain pulls the cable attachment portion in a direction substantially perpendicular to the direction of the straight line L3 (the direction V1 shown in the drawing). The arm pressing portion 64e is oriented substantially perpendicular to the direction of the straight line L3 (the direction shown in the figure) V2) Pressing the pressure on the rod side of the rod side arm 62. As shown in Fig. 18, the interlocking lever 4B has a stop for limiting the amount of rotation of the equalizer to no more than a predetermined amount. Figure 34 is a front elevational view of the base 40c, 40d of a chain brake lever 40B. As shown, the stop member 4A is a projection projecting from the base portion 40d toward the base portion 40c. The stopper 4 (h is formed at a position slightly away from the arm pressing portion 64c in the direction in which the arm pressing portion 64c of the equalizer 64 is moved when the interlocking lever 4b is operated. Now, the braking device 10B is explained. Figure 24 and Figure 25 are diagrams for explaining the operation of the brake device 1〇B when the interlocking brake lever 40B is operated. Fig. % is a diagram for explaining the operation of the brake device i when the current rim lever 2 is operated. Fig. 27 is a diagram for explaining the inner cable 128149.doc • 28· 200918406 Figure of the operation of the brake device 10B when not connected. Fig. 28 is a diagram for explaining the operation of the oil leakage from the hydraulic path 12; The 32B and the interlocking brake lever 4〇b are simplified, and the rotation season exclusive restriction portion 32c of the master cylinder 32B and the interlocking brake member 40f of the interlocking brake lever are not. The inner cable of the rear wheel brake cable has a long double dashed line. The operation of the brake device 10B when the interlocking brake lever 4〇B is operated will be described with reference to Fig. 24 and Fig. 25. When the interlocking brake lever_ is pulled to the gripper as shown in Fig. 24 and starts to rotate, the balance is balanced. The device 64 starts to move with the interlocking brake lever 4〇B in the lateral direction of the vehicle width (the direction w” shown in the figure. At this time, the U4 hometown cable attachment portion 64b will be within the rear wheel. Cable 11 & pulls outward according to the width direction of the vehicle, and f is pressed to the side of the lever side arm In this manner, the rear wheel brake (5) is initially actuated. On the other hand, since the propulsion member 65 has previously pulled the propulsion member attachment portion 62f of the lever side arm 62, the front wheel brake 14 does not start to operate. The pusher member 65 pulls the pusher member attachment portion 62f of the lever side arm 62 in a direction opposite to the direction in which the equalizer 64 applies ink to the lever side arm 62. Therefore, the lever side dam 62 and the cylinder side arm 63 are at the pusher member 65 The arm biasing portion 64c of the urging force and equalizer μ is used to push the force of the lever-side pressure receiving portion 62c to be balanced without being rotated. Therefore, the front wheel brake 14 is not actuated immediately when the interlocking brake lever 4〇B is initially operated. When the interlocking lever 40B is further pulled toward the grip as shown in Fig. 25, and when the equalizer 64 is used to urge the lever side arm 62 to a greater force than the pushing member 65, the lever side arm 62 and the cylinder side arm 63 rotates with each other, and the cylinder pressing portion 63a of the cylinder side arm 〇 128149.doc -29- 200918406 presses the pressure receiving portion 32a of the master cylinder 32B. In this way, the front wheel brake 14 is also actuated. The rotary support portion 64a of the equalizer 64 supported by the interlocking brake lever 40B is positioned between the arm pressing portion 64c and the cable attachment portion 64b (see Fig. 21). One of the operating forces of the interlocking brake lever 40B is divided into a slave cable attachment portion 64. The force input to the rear wheel brake 17 (the cable attachment portion 64b pulls the inner cable 11a-force) and a slave arm The pressing portion 64 £: the force input to the front wheel brake 14 (the arm pressing portion f 64 (the force applied to the lever side arm 62). The division ratio is attached from the center P2 of the rotation support portion, the portion 64a to the cable The ratio of the distance of the center P3 of the portion 64b to the distance from the center P2 of the rotary support portion 64a to the arm pressing portion 64c is determined. Therefore, the division ratio of the equalizer 64 is substantially constant throughout the rotation of the interlocking brake lever 4B. Next, the operation of the brake device 10B will be described with reference to Fig. 26. When the current rim lever 20 is pulled toward the grip (see Fig. 3), the inner cable 24 of the transmission cable 21 pulls the tension portion 63e of the cylinder side arm 63 toward the vehicle width. In the direction shown in the figure, the cylinder dusting portion 63a of the cylinder side arm 63 presses the pressure receiving portion 32a of the master cylinder 32B to actuate the front wheel brake 14 and the cylinder side arm as shown in FIG. The pressed portion 63c of 63 is removed from the pressing portion 62a of the rod side arm 62, and the rod side arm 6 2 and the interlocking brake lever 40B are maintained at their respective positions. Next, the operation of the brake device 10B will be described with reference to Fig. 27. When the interlocking brakes B are pulled in the state where the inner cable 1 1 a is not connected in the rear wheel brake cable 11 The rotary support portion 64a of the ^ equalizer 64 is moved in the vehicle width direction. At this time, the equalizer 64 is received from the rod side pressure receiving portion 62c of the rod side 128149.doc • 30· 200918406 # 62 without resisting the arm pressing portion 64c. The rod side arm 62 and the cylinder side arm 63 maintain their positions. In this way, it is possible that the interlocking lever side is operated when the cable is not connected within the rear wheel axle 11 It is prevented that only the front wheel brakes 4 are actuated. Next, the operation of the brake device 1〇B will be described with reference to Fig. 28. When the chain brake lever 40B is pulled to the grip 'when the oil is leaking from the hydraulic path 12, In the case shown in Fig. 24, the equalizer 64 only pulls the rear wheel before the equalizer is biased by the arm pressing portion 64c toward the rod-side pressed portion of the lever side arm 62 and the driving force of the pushing member 65 is balanced with each other. Brake cable I. Then, when the chain 煞When the rod 40B is further pulled toward the grip 讣, the reaction force of the arm pressing portion 64c of the equalizer 64 received by the (four) center of the rod side of the rod side arm 62 cannot become greater than the urging force of the pushing member 65 or higher. Therefore, the equalizer 64 is pulled by the rear wheel brake cable l to be rotated. Then, as shown in Fig. 28, the arm pressing portion of the equalization | 564 becomes contact with the stopper provided in front of the arm pressing portion 64c. By this, the equalizer (1) is further adjusted. The further step-by-step rotation of the Hb 'equalizer 64 pulls the rear wheel brakes further outward in the vehicle width direction, allowing the rear wheel brakes 17 to further apply a braking force. In the above-described brake device 1 均衡, the equalizer 64 is used as a member for turning the operating force of the interlocking brake lever into the rear wheel brake 17 and the front wheel brake 14. The equalizer 64 divides one of the operating forces on the side of the interlocking brake lever into a force input to the rear wheel brake 17 and a force input to the front wheel brake 14, the division ratio being from the center of the rotary support portion 64a of the equalizer 64 to The distance between the arm pressing portion 64c and the distance from the 立 4 4 、 * * * * 、 附 附 附 附 附 附 附 附 附 附 附 附 附 附 附 。 。 Therefore, 128149.doc 200918406 Γ In the case where the inner cable (10) becomes slightly lengthened due to aging, the ratio of a Α in the operation of the interlocking brake lever 40Β is not affected by the aging phenomenon of the inner cable 1 U , so that the initial ratio is maintained.

Figure 31 is a cross-sectional view taken along line B-B of Figure 29. Fig. 32 is a cross section taken along line C-C of Fig. 29; in the drawings, portions similar to those described above will be given similar reference numerals and will not be described again. In the brake device 10C, as shown in Fig. 29, the chain brake lever 40 is attached to the left handlebar 4, and the front wheel brake lever 2 () is provided on the right handlebar*. The brake device U)C includes a lever η as an operating force transmitting member that transmits the longitudinal operation of the front wheel brake lever to the front wheel brake actuating mechanism 3A. The material is made of a rigid material such as a metal. The stroke is straight. The person can bend slightly in the middle part. The rod may be covered by a covering for covering the body (4) or may be placed behind a meter such as a speedometer so as not to be exposed to the outside. The rod 51 is arranged to extend from the handlebar 4 to the other. One end of the rod 51 is consumed by the incineration portion 3 le of the arm 31, and unlike the aforementioned transmission cable 21, the relative movement between the rod 5i and the tension portion 31e is restricted. Specifically, as shown in Fig. 30, a coupler 52 for the end of the transfer lever si and the pull portion 128149.doc • 32-200918406 portion 31e is provided at the end of the rod 51. The coupler 52 includes a base portion 52a and a pair of plates 52b, 52b extending perpendicularly from the base portion 52a. The rod 51 is formed through a hole 52c formed in the base portion 52a, and a joint portion 51a having a diameter larger than the hole 52c is formed at the end of the rod 51. The joint portion 5A is provided in the coupler 52, and is held by the base portion 52a and the dog-out portions 52d, 52d formed by the inward deformation of the pair of plates 52b, 52b. The tensioned portion 3ie is disposed between the pair of plates 52b, 52b and is coupled by a pin 53. That is, a hole having a size corresponding to the diameter of the pin 53 is formed in each of the pair of plates 52b, 52b and the tensioned portion 3le, and the pin 53 passes through the holes. An open end pin 54 is inserted into one end of the pin 53 to prevent the pin 53 from slipping off. In this manner, the rod 5丨 and the tensioned portion 3丨e are lightly coupled together so that the relative movement therebetween is restricted. In the pair of plates 52b, each of which has a hole having a size corresponding to the diameter of the pin 53 is formed. Alternatively, as shown above, an elongated hole (see Fig. 14) for forming the transmission cable 21 for the brake device 1 can be formed in the pulling portion 21 (the same), and the elongated hole is used instead of the hole of the plate.

As shown in Fig. 29, the front wheel brake lever 2〇C is rotatably attached to the attached cow C branch of the handlebar 4. That is, like the aforementioned front wheel brake lever 2, the support portion 2〇c is provided at the base of the front wheel brake lever 2〇c. A member 24 (e.g., a bolt) passes through a hole formed in the support portion of the paper and a hole </ RTI> in the attachment member 23C and the front rim lever 2 〇c is rotatable about the shaft display 24. 〒 In addition to the support part 2〇, the 丨 〇 2〇d is provided in the front rim. The rod 51 is coupled in a state in which it is restricted not only to the movement of the tension portion 31 of the arm 31 but also to the relative movement of the rod pure portion ^ 128149.doc -33 - 200918406. The lever 51 is provided with an adjustment mechanism 55 (see Fig. 用于) for adjusting the distance between the rod coupling portion 20d and the tension portion 31e. Specifically, as shown in FIG. 31, the other end of the rod 51 is coupled to the rod coupling portion 2〇d by a coupler. Like the aforementioned coupler 52, the coupler % includes a base portion 56a and a pair of plates 56b, 56b having a rod 51 passing through a hole 56c. The rod coupling portion 20d is disposed between the pair of plates 56b, 5'' and is coupled by a pin 57. An open end pin 58 is inserted into the distal end of the pin 57 to prevent pin slippage. A thread 51b is formed on the outer peripheral surface of the other end of the rod 51, and the base is held between the two nuts 55a, 55b fitted to the thread 51b. In this manner, the rod 51 is coupled to the rod coupling portion 2〇d by the coupling 56. The relative movement between the rod 5 1 and the rod coupling portion 2〇d is limited. Therefore, in the brake car loading £1GC, when the Dang (4) car 4G is operated to move to the grip, the movement of the chain brake lever 40 is transmitted to the front wheel brake lever 2〇c so that the front wheel brake lever 20C is also moved to the grip 4&amp; Rotate. In this way, it is possible to improve the operability of both of the interlocking brake lever 40 and the front brake lever 2GC in the case of being successfully operated. That is, when the interlocking brake lever 4 () starts the front wheel brake lever paper in the middle of the grip, the movement of the front wheel brake lever eagle is immediately transmitted to the arm 31, so that the front rim (four) can be applied to For example, the operating force of the rim 梓 20 C is activated. The size and position of the chain brake lever 4〇, the front wheel brake lever paper, the arm 31, and other portions are set such that when the interlocking brake lever 40 is operated (when the interlocking brake lever 40 is moved into contact with the grip 4b), The amount of movement of the front wheel brake (4) c does not exceed the movable range of the front wheel brake lever 2GC (the range from the position before the operation to the position where it comes into contact with the grip 4a). For example, the dimensions of the arms 128149.doc-34.200918406 31 and the front wheel brake lever 20C are set such that the center of rotation of the front wheel brake lever 2〇c (the center of the journal member 24) to the rod consumption portion 2〇d The distance is greater than the distance from the center of rotation of the arm 31 (the center of the journal member 43) to the tensioned portion W. As shown in FIGS. 29 and 31, the adjustment mechanism 55 is composed of two nuts 55a, 55b and a thread 51b, and the rod coupling portion is adjusted between the rod coupling portion 20d and the tension portion 3 1 e by rotating the thread 51b. the distance. That is, by rotating the thread 51b relative to the nut 55a, 55b to move the position of the nut 55a, 55b on the stem 51, the attachment position of the coupler 56 is moved in the longitudinal direction of the rod 5 to adjust The distance between the rod coupling portion 2 〇d and the tension portion 3丨e. The wheel rim 20C is configured to be rotated beyond the front position of the front wheel brake lever 2〇c in a state away from the grip 4a in a state before the rod 51 is connected (see FIG. 29), that is, the rim rim 2〇c The position at the time of operation (the position of the front wheel brake lever 20C shown in Fig. 29). The initial position of the front wheel brake lever 2〇c can be set at an appropriate position within the movable range of the front wheel brake lever 2〇c by adjusting the distance between the rod coupling portion 2〇d and the tension portion 3 le by the adjusting mechanism 55. That is to say, the initial position of the grip portion 20a of the front wheel brake lever 20C may be due to the attachment position of the rotation lever 5 1 , the movement coupling 56 on the rod 5 1 , and the enlarged rod portion 20d and the tension portion. The distance between the 3 le is brought closer to the grip 4a °. The initial position of the grip portion 2〇a can be taken by reducing the distance between the rod engaging portion 20d and the tension portion 3 e Go blunt away from the grip. In some cases, the attachment position of the attachment member 2 3 C on the handlebar 4 may be misaligned due to manufacturing differences or the like, and thus the initial position of the front wheel brake lever 2〇c may be away from the grip 4 a too close or too far. Further, in these cases, the initial position of the grip portion 20a can be appropriately set by adjusting the distance between the rod coupling portion 2〇d and the tension portion 3 1 e. As shown in Fig. 32, the brake device loc is provided with a spring 29 for pushing the front wheel brake lever 20C in the direction of the pull lever 51. In the example, a spring holding portion 23a is provided at a position where the attachment member 23C faces the beauty of the front rim lever 2〇c. One end of the spring 29 is fitted in a recess 2315 formed in the spring retaining portion: 23a, and the other end is fitted in a recess 2〇6 formed in the base of the front rim lever 2〇C. The spring μ is a compression spring and exerts a force in a direction in which the base of the rim rim 20C and the spring holding portion 23a are separated from each other. The spring 29 prevents the front wheel brake lever 2〇c from sloshing to make a sound. In the above brake device 10C, the lever 51 is regarded as an operation force transmitting member. Therefore, it is possible to further reduce the transmission loss of an operating force in a transmission path from the front rim lever to the front wheel brake actuation mechanism. Since the rod does not become longer than the cable over time, the user does not need to perform the length adjustment work. Therefore, it is possible to prevent users from making improper adjustments.
