The brake hose 75 and the brake cable 77 are routed inside the front cover 45 and then gathered on the right side of the motorcycle 10 in the vehicle width direction. The brake hose 75 is connected to the front wheel brake 50 . The brake cable 77 is routed rearward and connected to the brake pedal 49 that operates the rear wheel brake 91 .
　燃料タンク２９の下面には、フロントフレーム１９を跨ぐための凹部が形成されている。この凹部の車幅方向右側の壁面に、ブレーキケーブル７７の中間部を支持するための固定部２９ａが設けられている。 A recess for straddling the front frame 19 is formed in the lower surface of the fuel tank 29 . A fixing portion 29a for supporting an intermediate portion of the brake cable 77 is provided on the right wall surface of the recess in the vehicle width direction.
　前輪ブレーキ５０は液圧式のディスクブレーキである。運転者がブレーキレバー７３を操作すると、マスタシリンダ７４からブレーキホース７５を介して、作動液が前輪ブレーキキャリパへ圧送される。前輪ブレーキ５０は、前輪ブレーキキャリパがブレーキディスクを押圧して生じる摩擦で前輪ＷＦを制動する。 The front wheel brake 50 is a hydraulic disc brake. When the driver operates the brake lever 73, hydraulic fluid is pressure-fed from the master cylinder 74 through the brake hose 75 to the front wheel brake caliper. The front wheel brake 50 brakes the front wheel WF with friction generated by the front wheel brake caliper pressing against the brake disc.
　後輪ブレーキ９１は機械式のドラムブレーキである。後輪ブレーキ９１は、ブレーキシューがドラムの内周面に押し付けられて生じる摩擦で後輪ＷＲを制動する。本実施形態に係る前後連動ブレーキシステムは、ブレーキレバー７３の操作に応じて前輪ブレーキ５０および後輪ブレーキ９１の両方が作動すると共に、ブレーキペダル４９の操作に応じて後輪ブレーキ９１が作動するように構成されている。 The rear wheel brake 91 is a mechanical drum brake. The rear wheel brake 91 brakes the rear wheel WR with friction generated by pressing the brake shoe against the inner peripheral surface of the drum. The front-rear interlocking brake system according to this embodiment operates so that both the front wheel brake 50 and the rear wheel brake 91 operate according to the operation of the brake lever 73, and the rear wheel brake 91 operates according to the operation of the brake pedal 49. is configured to
　ブレーキホース７５およびブレーキケーブル７７は、不図示の結束バンドで束ねられて、トップブリッジ３１とフロントカバー４５との隙間からフロントカバー４５の内側に配策される。ブレーキホース７５およびブレーキケーブル７７は、フロントカバー４５の内側に配策された後、自動二輪車１の車幅方向右側にまとめて配置される。 The brake hose 75 and brake cable 77 are bundled with a binding band (not shown) and routed inside the front cover 45 through the gap between the top bridge 31 and the front cover 45 . The brake hose 75 and the brake cable 77 are routed inside the front cover 45 and then collectively arranged on the right side of the motorcycle 1 in the vehicle width direction.
　図２は、自動二輪車１を車幅方向右側上方から見た斜視図である。また、図３は図２の一部拡大図である。図２では、燃料タンク２９を取り外した状態を示している。本実施形態では、ブレーキケーブル７７が車幅方向の中央より右側のみ、換言すれば、車体の中心線より車幅方向右側のみに配策される点に特徴がある。 FIG. 2 is a perspective view of the motorcycle 1 viewed from the upper right side in the vehicle width direction. 3 is a partially enlarged view of FIG. 2. FIG. FIG. 2 shows a state in which the fuel tank 29 is removed. This embodiment is characterized in that the brake cable 77 is routed only on the right side of the center in the vehicle width direction, in other words, only on the right side of the center line of the vehicle body in the vehicle width direction.
　ブレーキケーブル７７は、トップブリッジ３１とフロントカバー４５との隙間からフロントカバー４５の内側を通った後、燃料タンク２９やシート１７に隠された状態でフロントフレーム１９の車幅方向右側を通って後方に伸び、サイドカバー４７の後方で下方に湾曲してから、車幅方向右側のリヤブレーキペダル４９に向かって伸びる。この構成において、ブレーキケーブル７７は、常に車体の車幅方向右側にのみ存在する。これにより、ブレーキケーブル７７の配策作業が容易になると共に、メンテナンス性が向上する。また、車体外方からブレーキケーブル７７が視認される部分が少なく、自動二輪車１０の外観性も向上する。 The brake cable 77 passes through the inside of the front cover 45 through the gap between the top bridge 31 and the front cover 45, and then passes through the right side of the front frame 19 in the vehicle width direction while being hidden by the fuel tank 29 and the seat 17 to the rear. , bends downward behind the side cover 47, and then extends toward the rear brake pedal 49 on the right side in the vehicle width direction. In this configuration, the brake cable 77 always exists only on the right side of the vehicle body in the vehicle width direction. This facilitates the routing work of the brake cable 77 and improves maintainability. In addition, there are few portions where the brake cable 77 is visible from the outside of the vehicle body, and the appearance of the motorcycle 10 is also improved.
　左右一対のリヤフレーム２０には、同乗者が足を載せるピリオンステップ５０が取り付けられている。ピリオンステップ５０は、リヤフレーム２０に固定されるステー５１と、ステー５１の下端部に揺動可能に軸支される足載せ部５２とを有する。車幅方向右側のピリオンステップ５０のステー５１には、ブレーキケーブル７７の後端部を支持するための支持板５３が固定されている。支持板５３に固定されるブレーキケーブル７７の端部からは、ワイヤ７７ａが前方に伸びている。 A pair of left and right rear frames 20 are attached with pillion steps 50 on which a fellow passenger puts his or her feet. The pillion step 50 has a stay 51 fixed to the rear frame 20 and a footrest 52 pivotally supported on the lower end of the stay 51 so as to be swingable. A support plate 53 for supporting the rear end portion of the brake cable 77 is fixed to the stay 51 of the pillion step 50 on the right side in the vehicle width direction. A wire 77 a extends forward from the end of a brake cable 77 fixed to the support plate 53 .
　ブレーキペダル４９の後部には、後方延出部４９ａが設けられており、後方延出部４９の上端部は、揺動自在のイコライザ４９ｂを介してワイヤ７７ａに連結されている。支持板５３とイコライザ４９ｂとの間には、リターンスプリング５４が係合されている。 A rearwardly extending portion 49a is provided at the rear portion of the brake pedal 49, and the upper end of the rearwardly extending portion 49 is connected to the wire 77a via a swingable equalizer 49b. A return spring 54 is engaged between the support plate 53 and the equalizer 49b.
　この構成により、ブレーキレバー７３の操作に伴ってブレーキケーブル７７のワイヤ７７ａが牽引されると、ブレーキペダル４９が時計方向に揺動して後輪ブレーキ９１が作動する。本実施形態では、ブレーキワイヤ７７の後端部がピリオンステップ５０に支持されることで、ピリオンステップ下のスペースを有効活用することを可能としている。また、ブレーキケーブル７７の後端部を、既存の部品を用いて適切な位置に支持することが可能となる。 With this configuration, when the wire 77a of the brake cable 77 is pulled along with the operation of the brake lever 73, the brake pedal 49 swings clockwise and the rear wheel brake 91 operates. In this embodiment, the rear end portion of the brake wire 77 is supported by the pillion step 50, thereby making it possible to effectively utilize the space below the pillion step. Also, the rear end of the brake cable 77 can be supported at an appropriate position using existing parts.
　なお、自動二輪車の形態、前後連動ブレーキの構成、ピリオンステップの形状や構造、ブレーキケーブルの長さや取り回し経路等は、上記実施形態に限られず、種々の変更が可能である。例えば、ブレーキケーブルは、車体の中心に対して車幅方向左側にのみ配策してもよい。本発明に係るブレーキケーブルの配策方法は、自動二輪車に限られず、鞍乗型の三輪車や四輪車等に適用することが可能である。 It should be noted that the form of the motorcycle, the configuration of the front and rear interlocking brakes, the shape and structure of the pillion step, the length and route of the brake cable, etc. are not limited to the above embodiment, and various modifications are possible. For example, the brake cable may be routed only on the left side in the vehicle width direction with respect to the center of the vehicle body. The brake cable routing method according to the present invention can be applied not only to motorcycles, but also to straddle-type three-wheeled vehicles, four-wheeled vehicles, and the like.
