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. The large diameter portion of the piston is disposed, the adjustment nut is biased in the braking direction by a spring, the adjustment bolt has its base end locked on the inner periphery of the hydraulic pressure chamber, and the retainer and the head of the adjustment bolt are arranged. The sleeve piston is biased in the anti-braking direction by a spring contracted therebetween, and the sleeve piston engages its large diameter portion with the inner periphery of the hydraulic pressure chamber to restrict rotation and is movable. A braking action is performed by pressure fluid supplied from a fluid passage hole opened in the sleeve piston, and the other end of the sleeve piston is brought into contact with 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 operation by pushing the actuating piston through the braking gap automatic adjustment device, the retainer straddles a brinyder hole opening in an inner peripheral surface of the hydraulic pressure chamber. A liquid passage hole from a hydraulic pressure generation source is opened on the rear side of the cylinder from the retainer of the hydraulic chamber, and the liquid passage hole and the hydraulic pressure chamber are connected through a circumferential gap on the outer periphery of the large diameter part of the sleeve piston. A disc brake caliper device characterized by communication.
