Abstract
A force transmitting and converting mechanism for an electric braking device comprising a gear, a nut, a rotating body, a ramp mechanism, a screw member, and a brake element. The gear is rotated by the electric motor, and the nut disposed being opposed to the gear. The rotating body is disposed between the gear and the nut. The ramp mechanism is operated so that the gear and the nut can be separated from each other by a relative rotation of the gear with the nut. The screw member is screwed to the nut, and the brake element is capable of coming into contact with the screw member. The ramp mechanism integrally rotates the gear and the nut until the brake element comes into contact with the rotating member by a pushing force less than a predetermined value, and the ramp mechanism allows the gear and the nut to rotate relatively with each other when the brake element comes into contact with the rotating member by a pushing force not less than the predetermined value, so that the nut can be moved in a direction of the rotating member.
