Claims

[Scope of utility model registration request]

A support disposed near the edge of the rotor, a caliper that straddles the edge of the rotor and has a pad pressing mechanism on the inner side of the rotor and a reaction part on the outer side, and a caliper that is pressed against the rotor by this caliper. A sliding support means including a pair of friction pads, a pair of guide pins that support the caliper and the support so that they can move relative to each other along the axial direction of the rotor, and a pair of holes into which the guide pins fit. In the pin type disc brake, an elastic material is interposed between one guide pin of the sliding support means and its fitting hole, and the outer shape of the other guide pin and the inner shape of the hole into which it is fitted are respectively tapered. The guide pin is shaped so that when the guide pin and the hole are moved relative to each other in the axial direction of the rotor as the friction pad wears, the clearance between the guide pin and the hole in the radial direction is gradually increased. Pin type disc brake.
