Abstract

PURPOSE: To provide a centrifugal clutch wherein the ball contacting surface of a retainer weight is formed into a conical surface shape, and a spring retainer is brought into contact with the ball between a weight thrust plate and a retainer weight, whereby noise is prevented by a simple structure.
CONSTITUTION: When the rotational speed of the engine increases, a ball 8 moves in radial direction by the centrifugal force, and moves to the outer side by the ball contacting surface 10 of a concave conical shape of the retainer weight 9, and presses a weight thrust plate 6, a clutch plate 2 and a friction plate 4. Since the ball 8 comes into constant contact with the weight thrust plate 6, and a spring retainer 11 and the weight thrust plate 6 are positioned in parallel to each other, and the width of radial groove is constant, the ball 8 in its movement is retained at a predetermined position in the peripheral direction without receiving surplus force, whereby the vibraction in the lateral direction is defined to prevent noise.
