By operating, the hydraulic pressure is supplied to the front wheel brake 2 via the hydraulic pipe 9, and the front wheel brake 2 is operated in conjunction.
　マスタシリンダユニット６は、前輪ブレーキ２に液圧を供給する前記液圧マスタシリンダ６ａと、レバー機構６ｂとを組み合わせたもので、レバー機構６ｂは、第１回動レバー６ｃと、第２回動レバー６ｄと、ノッカー６ｅと、イコライザレバー６ｆとを備えている。第１ブレーキワイヤ８は、第１回動レバー６ｃに連結され、前輪ブレーキ用操作子４の操作レバー４ａを操作して第１ブレーキワイヤ８を牽引することにより、第１回動レバー６ｃが回動してノッカー６ｅを押動し、ノッカー６ｅが液圧マスタシリンダ６ａのピストン６ｇを押動することにより、昇圧した作動液が、液圧配管９を介して、前輪ブレーキ２に液圧が供給され、前輪ブレーキ２が単独で作動される。 The master cylinder unit 6 is a combination of the hydraulic master cylinder 6a for supplying hydraulic pressure to the front wheel brake 2 and a lever mechanism 6b. The lever mechanism 6b includes a first rotating lever 6c and a second rotating lever. A lever 6d, a knocker 6e, and an equalizer lever 6f are provided. The first brake wire 8 is connected to the first rotation lever 6c. By operating the operation lever 4a of the front wheel brake operation element 4 and pulling the first brake wire 8, the first rotation lever 6c is rotated. When the knocker 6e is moved to push the piston 6g of the hydraulic master cylinder 6a, the pressurized hydraulic fluid is supplied to the front wheel brake 2 via the hydraulic pipe 9. The front wheel brake 2 is operated alone.
　イコライザレバー６ｆには、第２ブレーキワイヤ１０と、後輪ブレーキワイヤ１１と、第２回動レバー６ｄとがそれぞれ連結され、後輪ブレーキ用操作子５の操作レバー４ａを操作すると、まず、イコライザレバー６ｆを介して後輪ブレーキワイヤ１１が牽引され、後輪ブレーキ３を作動させる。後輪ブレーキ３が作動し、後輪ブレーキ３からの反力が発生すると、イコライザレバー６ｆが傾いて、第２回動レバー６ｄを牽引し、第２回動レバー６ｄが回動するのに伴って第２回動レバー６ｄがノッカー６ｅを押動し、ノッカー６ｅが液圧マスタシリンダ６ａのピストン６ｇを押動することにより、昇圧した作動液が、液圧配管９を介して、前輪ブレーキ２に液圧が供給され、前輪ブレーキ２が連動して作動する。また、第２回動レバー６ｄと液圧マスタシリンダ６ａのシリンダボディとの間には、ディレイスプリング６ｈが配置され、前輪ブレーキ２を連動して作動させる際のタイミングが調整されている。 The equalizer lever 6f is connected to the second brake wire 10, the rear wheel brake wire 11, and the second rotation lever 6d. When the operation lever 4a of the rear wheel brake operation element 5 is operated, first, the equalizer is operated. The rear wheel brake wire 11 is pulled through the lever 6f, and the rear wheel brake 3 is operated. When the rear wheel brake 3 is activated and a reaction force is generated from the rear wheel brake 3, the equalizer lever 6f is tilted to pull the second rotating lever 6d, and the second rotating lever 6d rotates. The second rotating lever 6d pushes the knocker 6e, and the knocker 6e pushes the piston 6g of the hydraulic master cylinder 6a. The hydraulic pressure is supplied to the front wheel 2 and the front wheel brake 2 is operated in conjunction with it. Further, a delay spring 6h is disposed between the second rotating lever 6d and the cylinder body of the hydraulic master cylinder 6a, and the timing for operating the front wheel brake 2 in conjunction with it is adjusted.
　また、図２に示されるように、このようなマスタシリンダユニット６は、バーハンドル車両１２のステアリング軸部の上方Ｂ１や、ヘッドライトの後方Ｂ２に配置することができる。 Further, as shown in FIG. 2, such a master cylinder unit 6 can be disposed above the steering shaft portion B1 of the bar handle vehicle 12 or behind the headlight B2.
　上述のように、第１形態例では、マスタシリンダユニット６を、バーハンドル車両１２のステアリング軸部の上方Ｂ１や、ヘッドライトの後方Ｂ２に配置することにより、マスタシリンダユニット６を配置するスペースを確保しやすい。さらに、車体のデザインを損ねることなくマスタシリンダユニット６を配置できると共に、外部からいたずらされる虞もない。また、ハンドルバー７に取り付けられた操作レバー４ａ，５ａに繋がる第１ブレーキワイヤ８や第２ブレーキワイヤ１０が、ハンドルの転舵によって引っ張られる虞がなく、良好なブレーキ操作フィーリングを保持することができる。さらに、後輪ブレーキ用操作子５を、ブレーキペダルではなく、ハンドルバー７に取り付けた操作レバー５ａで形成することにより、第２ブレーキワイヤ１０や後輪ブレーキワイヤ１１の配索が容易となる。 As described above, in the first embodiment, the master cylinder unit 6 is disposed above the steering shaft portion B1 of the bar handle vehicle 12 or behind the headlight B2, thereby providing a space for disposing the master cylinder unit 6. Easy to secure. Furthermore, the master cylinder unit 6 can be arranged without impairing the design of the vehicle body, and there is no possibility of being tampered with from the outside. Further, the first brake wire 8 and the second brake wire 10 connected to the operation levers 4a and 5a attached to the handle bar 7 are not likely to be pulled by the steering of the handle, and maintain a good brake operation feeling. Can do. Further, by forming the rear wheel brake operation element 5 with the operation lever 5a attached to the handle bar 7 instead of the brake pedal, the second brake wire 10 and the rear wheel brake wire 11 can be easily routed.
