Abstract

PURPOSE: To plan to minimize weight of a total braking device by constituting an arm guiding a brake-shoe integrally with a wheel cylinder and fixing the guide arm portion directly to a wheel-supporting portion such as a knuckle or the like.
CONSTITUTION: A pair of arms 7, 7a, extending in a shape of twin branches from an outer peripheral wall of a main body 40 constituting a cylinder 31, are constituted integrally with the main body 40. The arms 7, 7a are provided with bolt holes 8, 8a at intermediate portions thereof and with deep grooves 9, 9a, slidably guiding intermediate portions of webs 3, 3a for a pair of shoes 10, 10a, at tip end portions thereof. Pistons 5, 5a, equipped with seal rings 6, 6a respectively, are fitted in a cylinder 31 and upper portions of the webs 3, 3a are energized and urged to fit into deep grooves 4, 4a, provided at both end portions of the cylinder 31, by a resilient force of a detent spring 32. Lower ends of the brake-shoes 10, 10a are engaged by an anchor pin 33 respectively.
