Abstract
A cam housing assembly oscillates in association with rotation of an eccentric cam which is attached to a camshaft and is allowed to press a clutch by cam pins of the cam housing assembly. A pair of piston assemblies are provided of which each includes a piston which can slide within a sleeve, a spindle and a nut which screws on to the spindle and are supported in hole portions in a caliper body so as to oscillate therein, whereby a brake pad is pressed against by a plug after the spindle, the nut and the piston are sequentially pressed by pressing a clutch by the cam pins. Since the spindle and the nut are screwed on to each other through a reversible screw, a gap is adjusted automatically as the pad wears.
