Abstract

PURPOSE: To increase a pressure of a brake lining on a brake drum according to an operation of a brake by pivotally attaching the internal end of an arm, pivotally attached to the base end of brake band, at a part of a brake cover.
CONSTITUTION: When a crank 14 is turned in the direction of an arrow from the position shown by an assumed line, a base end 11a of a brake band 11 is turned about a pin 23 and shifted parallelly with the external face of a brake ring 13, while the primary rocking member 20 pivotally mounted on a part of a brake cover is associated with the rottion of the crank 14. The entiretail part 12a of a lining 12 and the rest as well simultaneously contact the external face of the brake ring 13 so that much more attraction force or contact pressure is created on the base end 11a for the subsequent control operation. When a much stronger braking is excuted, the secondary rocking member 30 contacts and presses the brake ring 13 against a pressure applied by a spring 39. When wheels are driven backward, the secondary rocking member 30 is used as a preceding shoe to generate a great braking force.
