Abstract
A brake apparatus includes a reciprocally rotating member which reciprocally rotates by an angular displacement smaller than 360.degree.. Two cam surfaces of different shapes are formed on the reciprocally rotating member. A brake drum rotates in association with the reciprocally rotating member. A brake lever is provided with a control arm which engages with a cam surface, and a brake arm which engages with the brake drum. The brake lever swings the brake arm toward or away from the brake drum in accordance with the shape of a cam surface. The control arm of the brake lever can elastically deform, so that it can be located in a position in which it can selectively engage with one of the cam surfaces at the same phase of rotation of the reciprocally rotating member during the forward and reverse rotations thereof.
