Claims

[Scope of utility model registration request]

A piston is inserted into a cylinder formed in a caliper, two annular bearings are driven at intervals into a cam hole formed in the caliper, and a camshaft that displaces the piston in the axial direction is inserted through both bearings. In a disc brake that is rotatably supported by a caliper, a part of the camshaft protrudes outside the caliper, and a brake lever for rotating the camshaft is attached to the protruding part, and the cam hole has a large diameter hole on the opening side. With or without a stepped hole on the bottom side or with a small diameter hole,
A disc brake in which a large diameter bearing is driven into the large diameter hole and a small diameter bearing is driven into the small diameter hole, and the camshaft is rotatably supported by the caliper via both bearings.
