。(Problems to be Solved by the Invention) In the above-mentioned prior art, a bottle with a head is used as the bottle that connects the brake part and the hub, and a disc spring and a washer are caulked to the tip of the bottle to connect the brake part and the hub. In order to fix the wheel to the axle, a bolt integrated with the axle was passed through the hub's mounting hole and a nut was screwed on. Since the head of the bottle or disc spring and the nut are arranged on the side of the hub, they must be placed apart from each other so that they do not interfere with each other. However, in small brakes, it is not possible to place them apart. There were times when it was difficult.

トを螺着するためのスペースは充分に確保される。(Means for solving the problem) The present invention makes it possible to form the connecting part between the braking part and the hub in a small size to avoid interference with nuts for fixing the axle, and to make the brake disc small and lightweight. The means for this is to provide a brake disc in which a hub is connected to the inner periphery of a ring-shaped brake part so as to be able to move minutely, and a bottomed receiving hole extending in the axle direction is provided in the brake part and the knob. , characterized in that a plurality of connecting parts are provided, each consisting of a steel ball accommodated in the receiving hole and a caulked part in which the opening of the receiving hole is caulked inward.8 (Function) With the above configuration, the braking part and The knobs are connected by a steel ball so as to be able to move minutely, and the braking torque is transmitted via the steel ball. Since the connecting portion is formed in a small size, there is sufficient space for screwing the nut for fixing the axle.

Further, the drilling of receiving holes, caulking, etc. are simple processes, and only inexpensive steel parts are used, so the brake disc can be manufactured at low cost and efficiently. Furthermore, since the connecting part is simple, it is easy to provide a large number of these and reduce the load per piece, making it possible to downsize the connecting part. Thin plate materials can be used, which is useful for reducing the size of brakes.
