する遠心クラツチ。A pair of clutch weights, each of which has a weight provided at one end of the arm and expands due to centrifugal force, are rotatably supported on respective support shafts fixed to the input member with the respective weights facing each other in the shape of a mouth. One end of each of a pair of return springs for reducing the diameter of the clutch weight is locked at a position near the weight end of each arm, and each other end is locked at a position opposite to the weight end and near the support shaft, and the input member In a centrifugal clutch that transmits rotational force applied to each of the clutch weights, the input member is formed of a plate-like member, and the input member is formed of a plate-like member near each weight end of the plate-like member and closer to each of the return springs. A centrifugal clutch characterized in that a guide portion for guiding each arm along the rotational direction of each arm is formed integrally with the plate-like member by cutting and bending at a position closer to the support shaft.
