Abstract

PURPOSE: To prevent the dragging of a brake shoe due to overregulation at a time when a brake drum is of high temperatures by forming an overregulation-preventing spring of a configuration memory material in order to lower the spring load during high-temeprature period.
CONSTITUTION: When supplying a pressure liquid to the central chamber of a cylinder 16 at the time of braking, a pair of brake shoes 1 are pressed on the inner surface of a brake drum to generate a braking force. If the gap between the drum and shoe 1 is greater than a set value at this time, an overregulation-preventing spring 21 is pulled together with a wire 18 as the expanding movement of the right- handed shoe 1 proceeds and then a regulating lever 10 is turned clockwise around a pin 9 as the center. Thus, a ratchet wheel 12 is turned, a relatively turning extending member 11 is extended, and the braking gap is reduced. The said spring 21 is molded of the configuration memory material in such a way as to reduce the spring load at high temperatures at which the brake drum is thermally expanded.
