Claims

[Scope of utility model registration request]

In the hydraulic pressure chamber defined by the actuation piston engaged in the cylinder of the actuating part of the caliper, there are an adjustment nut and an adjustment bolt screwed together with a multi-thread screw of the automatic braking gap adjustment device, and a sleeve that transmits the mechanical actuation 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 regulate rotation and is movable, and is used for braking action by hydraulic pressure supplied from a fluid passage opening into the hydraulic pressure chamber. and bringing the other end of the sleeve piston into contact with the working end of a bushing rod operated by mechanical operation,
In a disc brake caliper device that performs a braking operation by pressing a sleeve piston through the operation of the bushing rod and pushing the working piston through the automatic braking gap adjustment device, the large diameter portion of the sleeve piston includes:
providing a retaining portion that engages with the head of the adjustment bolt;
A multi-latch surface that frictionally engages with the clutch portion of the adjustment bolt is formed on the peripheral edge of the retaining portion, and a head engaging portion of the adjust bolt is formed on an extending portion formed from the clutch surface of the retaining portion toward the opening side. A caliper device for a disc brake, characterized in that it is provided with a member for preventing mating and coming off.
