Abstract

PURPOSE: To prevent the over-regulation under high temperature by operating an actuator when the temperature of a brake shoe detected by a temperature sensitive resistor element will exceed over predetermined level thereby disengaging a regulation lever from a nail wheel of a relative rotation expansive member.
CONSTITUTION: When supplying the liquid pressure to a hydraulic cylinder 1 at the braking, a pair of pistons 2 are pushed outwardly to enlarge a pair of brake shoes 5 to be pushed against the inner circumferential face of a brake drum thus to produce the braking force. At this time a regulation lever 3 is pulled by a spring 12 to be rotated clockwise around a shaft 15, but when the brake gap is larger than predetermined lever a screw shaft 19 is rotated together with a nail wheel 18 thereby the brake gap is regulated by the expansion of a start 4. When a temperature-sensitive resisror element 21 will detect the temperature rise of the shoe 5 higher than predetermined level, an electromagnetic actuator 22 is excited to move said lever 3 to the direction departing from the nail wheel 18 thereby the brake gap regulating operation is interruped.
