　次にこの第１の実施の形態の作用について説明すると、イコライザ２８の一端部（下端部）に作動アーム２７の上端部が連結され、前輪ブレーキＢＦ１に操作力を伝達する連動用ブレーキケーブル２９がイコライザ２８の他端部（上端部）に連結され、後輪ブレーキＢＲに操作力を伝達するブレーキロッド３０がイコライザ２８の中間部に連結されるので、図４（ａ）で示すようなブレーキペダル２６の非操作状態からブレーキペダル２６を踏み込み操作すると、ブレーキペダル２６の踏み込み操作に応じて該ブレーキペダル２６が回動し、イコライザ２８は、図４（ｂ）で示すように、その他端部側の前記ストッパ３５ｃの当接部を支点として作動アーム２７の移動方向と同一方向に作動し、イコライザ２６の中間部に連結されたブレーキロッド３０に、ブレーキペダル２６の回動に伴う作動アーム２７の移動方向と同一方向の力が作用する。この際、連動用ブレーキケーブル２９が連結される部分で前記イコライザ２８にストッパ３５ｃが前方から対向しているので、連動用ブレーキケーブル２９にイコライザ２８から力が作用することはない。 Next, the operation of the first embodiment will be described. An upper end portion of the operating arm 27 is connected to one end portion (lower end portion) of the equalizer 28, and an interlocking brake cable 29 that transmits an operating force to the front wheel brake BF1 is provided. A brake rod 30 connected to the other end portion (upper end portion) of the equalizer 28 and transmitting an operating force to the rear wheel brake BR is connected to an intermediate portion of the equalizer 28, so that a brake pedal as shown in FIG. When the brake pedal 26 is depressed from the non-operating state of FIG. 26, the brake pedal 26 rotates according to the depression of the brake pedal 26, and the equalizer 28 is connected to the other end side as shown in FIG. The breaker connected to the middle part of the equalizer 26 is operated in the same direction as the movement direction of the operating arm 27 with the contact part of the stopper 35c as a fulcrum. The rod 30, the moving direction and in the same direction force of the operating arm 27 caused by the rotation of the brake pedal 26 is applied. At this time, since the stopper 35c faces the equalizer 28 from the front at the portion where the interlocking brake cable 29 is connected, no force is applied to the interlocking brake cable 29 from the equalizer 28.
　ブレーキペダル２６の踏み込み操作力を大きくすることでブレーキペダル２６がさらに回動すると、ブレーキロッド３０からの反力が大きくなっているので、イコライザ２８の中間部の前記ブレーキロッド３０の連結点Ｐを支点として前記イコライザ２８の他端部に前記作動アーム２７の移動方向とは逆方向の力が作用することになり、その力が遅延ばね３６のばね力を上回ると、図４（ｃ）で示すように、前記イコライザ２８の他端部が前記作動アーム２７の移動方向と逆方向に回動することになり、連動用ブレーキケーブル２９に作動アーム２７の移動方向とは逆方向の力をイコライザ２８から作用させることができる。 When the brake pedal 26 is further rotated by increasing the depressing operation force of the brake pedal 26, the reaction force from the brake rod 30 increases, so that the connection point P of the brake rod 30 in the intermediate portion of the equalizer 28 is set. As a fulcrum, a force in the direction opposite to the moving direction of the operating arm 27 acts on the other end portion of the equalizer 28. When the force exceeds the spring force of the delay spring 36, it is shown in FIG. As described above, the other end portion of the equalizer 28 rotates in the direction opposite to the moving direction of the operating arm 27, and a force in the direction opposite to the moving direction of the operating arm 27 is applied to the interlocking brake cable 29. Can act from.
　またスイングアーム１８の下縁１８ａよりも上方に、ブレーキロッド３０およびイコライザ２８の連結点Ｐが配置されるので、ブレーキペダル２６の基端部すなわち作動アーム２７の基端部からブレーキロッド３０およびイコライザ２８の連結点Ｐまでの距離を比較的大きく確保することができ、作動アーム２７の作動量を大きくとることができるとともに、イコライザ２８の前方にエンジンＥとの干渉を回避しつつ連動用ブレーキケーブル２９を容易に配索することができる。 Further, since the connecting point P of the brake rod 30 and the equalizer 28 is disposed above the lower edge 18a of the swing arm 18, the brake rod 30 and the equalizer are connected from the base end of the brake pedal 26, that is, the base end of the operating arm 27. 28, the distance to the connecting point P can be secured relatively large, the operating amount of the operating arm 27 can be increased, and the interlocking brake cable is provided in front of the equalizer 28 while avoiding interference with the engine E. 29 can be easily routed.
　また前記後輪ＷＲの車軸３１の中心と、スイングアーム１８の前端部を車体フレームＦのピボットフレーム１４に揺動可能に支承するピボット軸１９の中心とを結ぶ直線Ｌよりも下方で、前記ブレーキペダル２６の基端部が前記ピボットフレーム１４で回動可能に支承され、前記ブレーキロッド３０および前記イコライザ２８の連結点Ｐが、前記直線Ｌよりも上方に配置されるので、ブレーキペダル２６の基端部すなわち作動アーム２７の基端部からブレーキロッド３０およびイコライザ２８の連結点Ｐまでの距離を比較的大きく確保することができ、作動アーム２７の作動量を大きくとることができる。 In addition, below the straight line L connecting the center of the axle 31 of the rear wheel WR and the center of the pivot shaft 19 that swingably supports the front end of the swing arm 18 to the pivot frame 14 of the vehicle body frame F, the brake Since the base end portion of the pedal 26 is rotatably supported by the pivot frame 14 and the connection point P of the brake rod 30 and the equalizer 28 is disposed above the straight line L, the base of the brake pedal 26 is A relatively large distance from the end portion, that is, the base end portion of the operating arm 27 to the connecting point P of the brake rod 30 and the equalizer 28 can be secured, and the operating amount of the operating arm 27 can be increased.
　また前記連結点Ｐが、前記イコライザ２８の長手方向中心Ｃよりも前記イコライザ２８の一端側にオフセットして配置されるので、連動用ブレーキケーブル２９の連結点までのアーム比を確保して、連動用ブレーキケーブル２９に作用する力を確保することができる。 Further, since the connecting point P is disposed offset from the longitudinal center C of the equalizer 28 toward the one end side of the equalizer 28, the arm ratio to the connecting point of the interlocking brake cable 29 is secured and interlocked. The force acting on the brake cable 29 can be ensured.
