<p><P>PROBLEM TO BE SOLVED: To provide an electric brake device that accurately controls operation. <P>SOLUTION: Driving force of an electric motor 14 attached to a brake housing 13 rotates a screw 181 and moves a nut 185 in the rotation axis direction. The nut 185 presses a piston 20, and biases a first brake pad 21a toward a disk rotor 4. A caliper 131 having received reaction force from the first brake pad 21a biases a second brake pad 21b toward a disk rotor 4. A sensor holder 16 with a load sensor 17 attached thereon is attached to the caliper 131 movably in the rotation axis direction, and the screw 181 is attached to the sensor holder 16 via a ball bearing 182. A wave washer 184 biases an outer race 182a of the ball bearing 182 in the reaction force direction to the caliper 131, and brings a load sensor 17 into contact with the brake housing 13. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
