Claims

[Scope of utility model registration request]

In the hydraulic pressure chamber defined by the operating piston fitted in the cylinder of the operating part of the caliper, there are an adjustment nut and an adjustment bolt fitted with a multi-thread screw of the automatic braking gap adjustment device, and a sleeve that transmits the mechanical operating force. A large diameter portion of the piston is disposed, the adjustment nut is biased in the braking direction by a spring, and the adjustment bolt is compressed between a retainer whose base end is fixed to the inner periphery of the hydraulic pressure chamber and the head of the adjustment bolt. The installed spring biases the brake in the anti-braking direction,
Further, the sleeve piston has a large diameter portion that engages with the inner periphery of the hydraulic pressure chamber to restrict rotation and is slidably provided, and is braked by pressure fluid supplied from a fluid passage hole that opens into the hydraulic pressure chamber. and engaging the other end of the sleeve piston with the working end of a bushing rod actuated by mechanical operation;
In a disc brake caliper device in which a sleeve piston is pressed by the operation of the bushing rod and the operating piston is pushed through the braking gap automatic adjustment device to perform a braking operation, the sleeve piston has a large diameter portion and a small diameter portion. A pressure fluid supply chamber is defined between the body and the inner wall of the cylinder that connect these two parts, and a fluid communication hole from a fluid pressure generation source is opened in the pressure fluid supply chamber to supply pressure fluid. 5. A caliper device for a disc brake, characterized in that the chamber and the hydraulic pressure chamber are communicated through a circumferential air gap between the inner wall of the cylinder and the large diameter portion.
