Claims

[Scope of utility model registration request]

A caliper with a built-in piston that presses a pad on one side of the disk against the disk and a reaction force of the piston that presses a pad on the other side of the disk against the disk is inserted into a hole in either this or the fixed support member. is supported movably in the disk axial direction by a fixed support member via a guide pin fixed to the other member, and seal portions at one end of the bellows portion are on both sides of the hole of the force member. A boot is installed in the inner circumferential groove of the opening to slidably support the guide pin, and a seal portion at the other end of the bellows portion is attached to the outer circumferential groove at the end of the guide pin. In the disc brake, a groove is formed on the outer periphery of the guide pin to communicate the internal space of the boot on both sides of the hole of the force member.
