Claims

[Scope of utility model registration request]

A caliper, which has a built-in piston that presses the pad on one side of the disk against the disk and uses the reaction force of this piston to press the pad on the other side of the disk, is inserted into the hole in either this or the fixed support member. The fixed support member is movably supported in the disk axial direction via a hollow guide pin fixed to the other member, and a seal portion at one end of the bellows portion is provided on both sides of the hole in front of the force member. is attached to the inner circumferential groove of the opening of the hole to slidably support the guide pin, and a boot is attached to the seal portion of the other end of the bellows portion or the outer circumferential groove of the end of the guide pin. In the installed disc brake, one end seal portion of each of the boots is pressed against the guide pin around its inner diameter, and the inner space of each of the boots is connected to the guide pin by a communication hole formed in the guide pin. The disc brake is connected to the inner hole of the disc brake, and the communication hole and the inner hole communicate with each other. , .
