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. and is movably supported in the disk axial direction by a fixed support member via a guide pin fixed to the other member, and a seal portion at one end of the bellows portion is attached to the opening of the hole on both sides of the hole of the one member. A disk is provided with a boot that is attached to an inner circumferential groove of the guide pin to slidably support the guide pin, and a seal portion of the other end of the bellows portion is attached to an outer circumferential groove of the end of the guide pin. A disc brake in which a high-rigidity thin tube is embedded in a seal portion at one end of each boot to communicate the internal spaces of the boots on both sides of the hole of the one member with each other through the hole.
