この発明は、オートバイのブレーキマスターシリンダに
関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a motorcycle brake master cylinder.
オートバイでは、前輪のブレーキは、ハンドレバーで操

て、最近では、油圧ブレーキが使用されることがある。On a motorcycle, the front brake is operated with a hand lever, and the rear brake is operated with a foot pedal. And recently, hydraulic brakes are sometimes used.
油圧ブレーキの場合は、後輪のブレーキ用のマスターシ

面倒でコスト高についている。In the case of hydraulic brakes, the master cylinder for the rear wheel brake is welded to the frame with two protruding bosses.
Tighten the master cylinder to this hole with bolts and nuts,
It is connected to the foot pedal by the brake iron. The central part of the car body where the master cylinder is installed has space constraints as electrical components, batteries, air cleaners, etc. must also be installed, and space for other parts must be used to install the master cylinder. The restrictions become greater. In addition, there is work to weld the bosses to the frame, bolts are used for installation, and the number of parts is large, making assembly difficult and expensive.
この発明は、かかる点に鑑み、スペースにゆとりができ

連結金具１と一体に鋳造することもできる。The connecting fitting 1 is made into a predetermined shape by casting,
The down tube 2 of the frame is placed on the left and right of the rear lower part of the vehicle body.
, the vertical tubes 3 are aligned at predetermined positions and joined together by welding. The connecting fitting 1 is also provided with a groove 5 for pivotally supporting the front end of the rear fork 4. A cylinder hole 6 is bored in one of the left and right connecting fittings 1. This cylinder hole 6 serves as a brake master cylinder, into which a brake component 7 is installed. Then, it is connected to a foot pedal 9 via a brake rod 8. The bracket 10 that pivotally supports the foot pedal 9 is designed to be fastened to the connecting fitting 1.
It can also be cast integrally with the connecting fitting 1.

れ、組付は手間も少くて済む。When the driver presses down the foot pedal 9 with his foot, the brake rod 8 is pushed, generating hydraulic pressure in the cylinder hole 6, which is transmitted to the rear wheel cylinder and brakes the rear wheel. . These are the same as those with normal master cylinders. Since the cylinder hole 6 is provided by drilling inside the connecting fitting 1, it does not take up space unlike a separate master cylinder, and there is ample space near the connecting fitting 1, making it easier to attach other parts. In addition, since the cylinder hole 6 for the master cylinder is bored inside the connecting fitting 1 and provided integrally, there is no need for fastening parts such as bosses and bolt nuts, which reduces the number of parts and reduces costs. It takes less time to attach.

ストダウンが図れ、組付けの手間も少（て済む。As explained above, the present invention connects the left and right down tubes and vertical tubes of the frame, and also provides a connecting fitting with a boss for attaching the rear fork, and a cylinder hole is drilled in the connecting fitting to brake the brake. Since the parts are assembled and the cylinder hole is used as the brake master cylinder, the brake master cylinder is created inside the connecting fitting and can be connected to the connector, freeing up space around it and making it easier to install other parts. In addition, since the master cylinder can be integrated into the connecting fitting, there is no need to weld the boss to the frame (and fastening parts such as gel nuts can be omitted, reducing the number of parts, reducing costs, and reducing assembly effort. (It's fine.
