<p>The present invention relates to a caliper brake comprising: a caliper housing (3) that has one end on which a fork (15) is formed and is bent; a brake cylinder (5) that generates a brake force inside the brake cylinder by means of an oil pressure of a damping oil transmitted from a brake line; a piston (7) that brakes by pressurizing a brake disc (10) between the piston and the fork (15) by means of the brake force generated in the brake cylinder (5) during braking; a pressurization rod part (9) that extends in an axial direction when abrasion occurs on the fork (15) and a frictional pad (17) of the piston (7), and increases a distance at which the piston (7) pressurizes the brake disc (10) and moves so as to compensate for the abrasion; and a return spring part (25) that is elastically compressed during braking, and is elastically restored when the brake is released such that the pressurization rod part (9) is returned to its original position before braking. As a result, a spring cage can be rotatably assembled with a rear end of the return spring part via a hanging hook that is bent in a L-shape so that a repulsive direction of the return spring part and an assembling direction of the spring cage are perpendicular to each other and thus do not coincide with each other. Therefore, coupling of the spring cage and a support plate is performed by one touch, and the assembling stability can be maintained at a high level. In addition, since the hanging hook is not required to have elasticity for coupling, the hanging hook can be relatively thick so that an assembling defect that occurs when the hanging hook is deformed or the durability of deterioration can be prevented in advance.</p> |
