Claims

[Scope of utility model registration request]

Transmits mechanical operating force to the adjustment nut and assist port, which are threaded with multiple helix screws of the automatic braking gap adjustment device, into the hydraulic pressure chamber defined by the operating piston fitted in the cylinder of the operating part of the caliper. The large diameter part of the sleeve piston is disposed, the adjustment nut is biased in the braking direction by a spring, and the adjustment bolt is inserted between the head of the adjustment bolt and a retainer whose base end is fixed to the inner periphery of the hydraulic pressure chamber. The contracted spring urges the sleeve piston in the anti-braking direction, and the sleeve piston engages the inner periphery of the hydraulic pressure chamber with its large diameter part to restrict rotation and is slidably provided. A braking action is performed by the pressure fluid supplied from the opening fluid passage hole, and the other end of the sleeve piston is fitted into the working end of a bushing rod that is operated by mechanical operation, and the sleeve piston is pressed by the action of the bushing rod. In a disc brake caliper device that performs a braking action by pushing the actuating piston through the braking gap automatic adjustment device, the sleeve piston is provided with an appropriate number of pins implanted at the rear end of a large diameter portion of the sleeve piston. engages with the wall of the hydraulic chamber to restrict rotation, and a part of the rear end of the large diameter portion,
A caliper device for a disc brake, characterized in that an arc-shaped groove is formed leaving the pin-planted part, and a liquid passage hole for introducing pressure liquid from a hydraulic pressure source is opened at a position facing the groove. .
