Abstract

PURPOSE:To make larger the energizing force to the radius direction outer side of a holding base to a torque transmitting body by providing a first energizing part to energize the torque transmitting body to an axis direction upper side through a plate spring, arranging the application point of the first energizing part in the neighborhood of a pivot and providing a second energizing part in another end part of the plate spring. CONSTITUTION:A first energizing part 42 provided to a plate spring 32 presses the whole plate spring 32 on the rear face of a holding base 34 by its energizing force and energizes a torque transmitting body 31 to the axis direction upper side. A second energizing part 40 provided to the plate spring 32 engages elastically with a spring bearing 36 provided projectionally on the rear face of the holding base 34 and energizes the torque transmitting body 31 to the radius direction outer side of the holding base 34. Further, the application point of the first energizing part 42 is arranged in the neighborhood of a pivot 35. Consequently, when the plate spring 32 turns with the pivot 35 as a center, the length in which the first energizing part 42 rubs can be shortened. Thus, a frictional force accompanying the turn of the plate spring 32 can be made smaller and the energizing force to the radius direction outer side of the holding base 34 to the torque transmitting body 31 can be made larger.
