Abstract

PURPOSE: To avoid the change in the force of return springs over the total range of wear of shoe linings, by tightly installing the return springs between a right and a left brake shoes and the right and left members of a strut.
CONSTITUTION: A strut 7, which comprises a bolt 8, a nut 9, a gear 10 mounted on the bolt and a socket 11 rotatably fitted on the head of the bolt and engaged not to drop off, is provided between the opening portions of right and a left brake shoes 3, 2. A first return spring 16 is tightly installed between the brake shoe 2 and an adjuster lever 12 pivotally connected to the socket 11. A second return spring 17 is tightly installed between the nut 9 and the brake shoe 3. As a result, the force of each of the return springs 16, 17 is kept constant despite the elongation of the strut 7 to avoid the increase of the loss of the applied force for opening the shoes 2, 3.
