PURPOSE:To avoid the generation of sound of strike when an engaging member is engaged with a member to be engaged, by providing buffer members on one side of the facing parts of the member to be engaged and the engaging member of an engaging mechanism. CONSTITUTION:When an output shaft 10a is rotated, the rotary force of a flywheel 10 is transmitted to a rotary body 20 through plate springs 30, and the rotary body 20 is rotated. When the load is increased by the engagement of a clutch 13, each plate spring 30 is deflected. A phase difference is generated at a relative rotary angle position of each projection 23 of the rotary body 20 with respect to each projection 14 of the flywheel 10. Then, a torque-signal generating circuit M generates a torque signal through electromagnetic pickups 50a and 60. When the phase difference reaches the value corresponding to the allowable deflection amount of each plate spring 30, a projection 43 of an annular boss 11 are engaged with projecton 41 of the rotary body 20. Buffer members 41a and 42a such as rubber are fixed to the projections 41 and 42. Sound of strike generated at the time of engagement is absorbed to the large extent, and noises from an engaging mechanism 40 are reduced. |
