Abstract
A rotational force transmitting device includes: an inertia wheel connected to an output gear; a spindle coupled freely rotatable to the center of the front surface of the inertia wheel; a power transmitting eccentric body extended vertically with respect to the rotary shaft of the spindle; an insert pin inserted into a guide hole, a position restoring spring inserted into the guide hole, for elastically supporting the insert pin in a backward direction; and a balance weight coupled rotatably to the rear surface of the inertia wheel, the balance weight rotating with the centrifugal force generated by the rotation of the inertia wheel to push the insert pin forward to allow the insert pin and the power transmitting eccentric body to be engaged with each other.
