Claims

[Scope of utility model registration request]

It has a fixed support placed on the edge of the disc rotor, a pair of friction pads on both sides that are pressed against the disc rotor, and a piston that presses one of the friction pads against the disc rotor, and moves by the reaction force. A caliper that presses the other friction pad against the disc rotor,
In a disc brake equipped with a support mechanism that supports a caliper movably in the axial direction of the disc rotor relative to a fixed support, the support mechanism is inserted into a blind hole with one end open formed in either the caliper or the fixed support. A cylindrical sleeve that is open at both ends to be slid together, and a threaded portion formed on the inner periphery of the sleeve located at one end of the open blind hole are fitted from the one end side and screwed together, thereby attaching the sleeve to the caliper. Alternatively, a bolt fixed to the other side of the fixed support is interposed between the circumferential surface of the fitting end of the bolt and the opposing circumferential surface of the sleeve, so that the inside of the blind hole is airtightly communicated with the outside air through the threaded portion. and a boot installed between one of the caliper or the fixed support in which the blind hole is formed and the outer peripheral surface of the sleeve to seal the sliding surfaces thereof, A caliper support mechanism for a disc brake, wherein the sealing member is configured to produce the sealing action when the bolt is inserted and assembled.
