<P>PROBLEM TO BE SOLVED: To provide an electric brake device configured so that a sensor for detecting the pressing force of a friction pad is less vulnerable to the frictional heat between the friction pad and the brake disc and can detect the pressing force of the friction pad with consistent accuracy. <P>SOLUTION: An electric brake device 1 has a rectilinear motion mechanism for converting the rotation of a rotating shaft 10 into the rectilinear motion of an outer ring member 12 and is configured so that the outer ring member 12 presses a friction pad 8 against the brake disc 2. The electric brake device 1 also has a reaction receiving member 14 for receiving a reaction force acting axially rearward when the friction pad 8 is pressed axially forward by the outer ring member 12. A fixed member 35 is provided axially behind the reaction receiving member 14, a row 37 of magnetic poles is provided to the reaction receiving member 14, and a magnetic sensor 38 is provided to the fixed member 35. <P>COPYRIGHT: (C)2013,JPO&INPIT |
