Abstract

PURPOSE:To perform braking during forward rotation, by providing a friction body, supported on a rotary shaft and being displaceable only in a given angle range in the direction of rotation, and a weight member, mounted to the friction body and spread and displaced by means of a centrifugal force. CONSTITUTION:Two pins 14 are secured to a friction body 12 engaged with a rotation transmission member through standing-up claw pieces 11a, and weight members 15, rotated around the pin 14 serving as a fulcrum and made of a metal, are mounted. The center of a curvature (r) of radius of the outer periphery of the weight member 15 is deviated from the axis of a rotary shaft, friction pieces 16 made of rubber are mounted to an outer peripheral surface part positioned closer to a tip, and a high centrifugal force is exerted on the weight member 15 being heavy. In which case, the weight member 15 is spread around the pin 14 serving as a fulcrum by means of a centrifugal force, and the friction piece 16 made of rubber, positioned closer to a tip, is forced into pressure contact with the inner surface of a cup member 17 to generate a brake force.
