Abstract:
PROBLEM TO BE SOLVED: To provide a damper pulley capable of restricting a local wearing.SOLUTION: There are provided a pulley 10 having an inner space and rotatable by power force supplied from outside; a hub 20, at least a part of it is arranged in the inner space that is rotatable and capable of outputting the power force to outside; and a clutch spring 50 fixed to the hub 20, engaged in friction with the inner peripheral surface of the pulley 10 and having its frictional engagement released on the basis of a relative rotation of the pulley 10 and the hub 20. The clutch spring 50 is resiliently deformed so as to have a reduced diameter. It has an outer wound part 51 arranged under a state in which it is pushed against the inner peripheral surface of the pulley 10. The outer wound part 51 is pushed against the inner peripheral surface of the pulley 10 with similar force over a range from a front end of the outer wound part 51 to its rear end in a front-rear direction.SELECTED DRAWING: Figure 4
