Abstract

PURPOSE: To prevent over-adjustment due to the elastic deformation of elements constituting the brakes by forming the preventive device so that the rotation of an adjusting lever after the clearances of the shoes disappear is prevented.
CONSTITUTION: When a parking lever 16 is turned strongly in order to obtain powerful braking force, mighty expanding force works to the shoes even after the shoes slide and contact to a drum, and the axial force of a strut 12 increases remarkably with the functioning. Accordingly, the rotational resistance of a washer 30 is increased, the rotational resistance of the adjusting lever 17 is augmented with the increase and rotation is prevented. Even when the strut 12 is further moved, the adjusting lever 17 does not move, a spring 26 is contracted and the movement of a strut 10 is absorbed. Thus, over-adjustment is not conducted because a tooth feeding section 22 of the lever 17 does not engage with an engaging section 14 and a star wheel 15 is not turned.
