Spring Type Clutch

摘要

The present invention relates to a power transfer clutch transferring rotary force which includes a first clutch body (100) receiving the rotary force from a driving shaft to be rotated; and a second clutch body (200) transferring the rotary force received from the first clutch body (100) to a driven shaft, wherein the rotary force of the first clutch body (100) is transferred to the second clutch body (200) as the first clutch body (100) is rotated while a roller (130) disposed at the first clutch body (100) is in contact with a cam protrusion (242) of a cam (240) disposed at the second clutch body (200), and a slip phenomenon, in which the roller (130) pushes the cam protrusion (242) of the cam (240) outside and climbs over the cam protrusion (242) of the cam (240), occurs if a predetermined amount of load is applied to a driven shaft connected to the second clutch body (200) while the rotary force is transferred.
