Claim Text:
1. A caliper brake apparatus that is configured to sandwich and to apply a frictional force to a disc which is rotatable together with a wheel, the caliper brake apparatus comprising: a caliper main body that is supported on a vehicle body; a brake lining that is configured to advance/retreat relative to the caliper main body and to apply the frictional force by slidingly contacting the disc; a guide plate that supports the brake lining; an anchor pin that supports the guide plate on the caliper main body such that the guide plate freely advances/retreats; a piston that is configured to advance/retreat relative to the caliper main body and to press against the brake lining via the guide plate; an elastic film that abuts a rear surface of the piston, defines a pressure chamber within the caliper main body and elastically deforms due to pressure of a working fluid within the pressure chamber so as to move the piston; and a piston plate that supports the piston on the anchor pin such that the piston freely slides, wherein the piston plate has a sliding hole into which the anchor pin is inserted, and the piston plate is configured to slide in an axial direction of the anchor pin to move parallel relative to the guide plate.
