<p><P>PROBLEM TO BE SOLVED: To provide a rotation fluctuation absorbing crank pulley configured to exhibit excellent torque transmission function and rotation fluctuation absorbing function, to prevent deformation of an elastic member even if a spring constant in a twisting direction of a coupling mechanism is set low, and to prevent damage to the elastic member. <P>SOLUTION: The rotation fluctuation absorbing crank pulley is formed by connecting a hub to a pulley via an elastic member so as to absorb rotation fluctuation to be generated in a drive shaft. A torque transmission mechanism with a sliding part formed by combining first and second sliding members is disposed between the hub and the elastic member. The second sliding member includes a sliding surface and a stopper surface. When a normal torque is input, the first and second sliding members slide to transmit the torque from the first sliding member to the second sliding member by sliding resistance generated accordingly. When an excessive torque is input, the torque is transmitted from the first sliding member to the second sliding member, with the first sliding member in contact with the stopper surface. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
