ABSTRACT:
A tooth formed on a brake pawl has, at a portion facing the outer peripheral surface of a brake gear coaxially mounted on the output shaft of the transmission, first and second inclined surfaces which are bounded by an intersectional line parallel to the axis of the output shaft. The inclination angle of each surface with respect to a tangent line passing through a point where the intersectional line is in contact with a circular path swept out by the outer peripheral surface of teeth formed on the brake gear is greater than zero degrees. With this, the brake pawl is pushed way from its engaged condition due to collisions between shoulder portions of the teeth and one of the first and second inclined surfaces above a predetermined vehicle speed.
