Abstract
PURPOSE: To prevent over-adjusting in a captioned adjuster by expanding a play gap in a connecting part between a bell crank and a brake shoe on one side when the operational force of an expanding device is increased over a fixed level.
CONSTITUTION: A fixed play gap (g) in a connecting part between a bell crank 11 of a contracting-position regulating strut 9 and a brake shoe 2' on one side is shaped by an escape lever 26 which detects the operational force of an expanding device of a wheel cylinder. The escape lever 26 is connected with an escape spring 30, and constructed to expand the paly gap (g) when it detects an operational force over a fixed level. For braking, when the expansion between brake shoes 2 and 2' surpasses a fixed value corresponding to the play gap (g), at first, the bell crank 11 is shifted by the escape spring 30 for automatically adjusting the gap of a brake drum. Even if brake shoes 2 and 2' and others are given elastic deformations, the bell crank 11 will not react to these deformations, and can make a proper gap- adjustment.
