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 in the anti-braking direction,
Further, the sleeve piston is provided such that its large diameter portion engages with the inner periphery of the hydraulic pressure chamber to restrict rotation and is movable, and is used for braking action by pressurized fluid supplied from a fluid passage opening into the hydraulic pressure chamber. At the same time, the other end of the sleeve piston is
A caliper of a disc brake that comes into contact with the working end of a bushing rod that is operated by mechanical operation, and that presses a sleeve piston due to the operation of the bushing rod to push the working piston through the braking gap automatic adjustment device to perform a braking action. In the device, the large diameter portion of the sleeve piston is provided with a retaining portion that engages with the head of the adjusting bolt, and a clutch surface that frictionally engages with the clutch portion of the adjusting bolt is formed on the periphery of the engaging portion. A caliper device for a disc brake, further comprising a stopper member having a leg portion that engages with the large diameter portion and a portion that prevents engagement and disengagement of the head of the adjustment bolt.
