To provide a technique which can reduce the force for depressing a brake pedal.
When a clutch lever 8 in (a) is turned clockwise, an leading corner part 9a of a brake shoe 9 comes into contact with an outer clutch sleeve 5 first as shown in (b). If an trailing corner part 125 comes into contact with an outer clutch sleeve 102b first as shown in (c), the trailing corner part 125 is pushed away by the outer clutch sleeve 102b and the braking action can not be achieved easily. In other words, in the case of (c), the force for depressing a brake pedal should be increased. On the contrary, in the case of (a), (b), because the brake is applied while the contact point of the brake shoe 9 with the outer clutch sleeve 5 is moving in the rotational direction, an excellent brake action can be achieved even if the force for depressing the brake pedal is relatively small.
