Abstract
It is an object of this invention to provide an automatic shoe clearance adjustment device for a drum brake mechanism designed to improve its durability by eliminating a gap, which is caused due to the manufacturing tolerances between the operating end surface of a brake shoe and the extended portion of an adjustment lever. To that end, a long hole ( ) is formed to extend horizontally in the actuating direction of a service brake actuator ( ); and the adjustment lever ( ) is pivotally supported via a pin ( ) with a capacity of making a rotation relative to the brake shoe ( ) and a capacity of making a relative slide in approximately the same direction in which the service brake actuator ( ) operates.
