Abstract

PURPOSE: In an overload preventive clutch using balls, to reduce an impact which occurrs when the balls contact with a clutch member, by shaping each projection of the clutch member to a form curved in the circumferential direction.
CONSTITUTION: When a planetary gear 20 is turned by a motor shaft 10, a clutch gear 16 is ready to be driven. However, as balls 35 are blocked by projections 35, the clutch gear 16 is probisbited from turning and rests stationary unless the balls 35 roll over the projections 31 against a spring force of a clutch spring 37. Therefore, only a holder 20a of the planetary gear 20 can turn to decelerate the revolution of a driving shaft 17. Once the shaft 17 is overloaded, the balls 35 move over the projections 31 against the spring force of the clutch spring 37 so that the projections 31 are forced to turn. The projections 31 are radially disposed and each of their slanting surface 32 is curved. A maximum torque may be controlled by turning a control 41 to change a spring force of the spring 37.
