ELECTRIC DISC BRAKE

WIPO Patent Application WO/2011/030839

A1

Disclosed is an electric disc brake that is low-cost and furthermore capable of maintaining superior resistance to weather. All of a shaft force sensor (8b) for measuring braking force is formed in the shape of a ring. The shaft force sensor (8b) is disposed around a rotating shaft that is rotationally driven by an electric motor and acts as the input unit of a force-increasing mechanism. The aforementioned shaft force sensor (8b) is equipped with one pair of pressing plates (47a, 47b) that are each formed in a ring shape and are disposed mutually parallel, a plurality of piezoelectric crystal elements (48, 48) that are sandwiched between both pressing plates (47a, 47b), and a lead wire (50) for extracting an electric charge generated with the pressing of each piezoelectric crystal element (48, 48) between both pressing plates (47a, 47b). Additionally, the lead wire (50) is pulled out to the outer diameter side of both aforementioned pressing plates (47a, 47b).
