Claims

[Scope of utility model registration request]

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