<p><P>PROBLEM TO BE SOLVED: To provide an electric disc-brake, in which a detent mechanism for an advance-retract mechanism causing a pressing force in a pressing member of a friction pad is formed so as to reduce load on a part by braking torque, durability of the detent mechanism is improved, and a low-priced detent mechanism is manufactured by simplifying the structure. <P>SOLUTION: The electric disc-brake effects the brakes by actuating the advance/retract movement mechanism by the driving force of an electric motor 15, and generates pressing force for the pressing member of the friction pads 3, 4. On either side of opposite faces of the pressing member and a friction pad 3 on the side of an active part 10, a straight protrusion 61 parallel with the tangential line of a disc rotor 1, or a plurality of protrusions 61 are provided on the same line parallel with the tangential line of the disc rotor 1. On the other side, a recess 60 fitting to the protrusion 61 is provided straightly. Thus, relative rotation of the pressing member and the pad 3 is prevented by the detent of the protrusion 61 and the recess 60. <P>COPYRIGHT: (C)2004,JPO</p> |
