<P>PROBLEM TO BE SOLVED: To provide an electric brake device that stabilizes a load input from a piston to a brake liquid. <P>SOLUTION: The electric brake device is configured to axially drive a piston by a drive force to generate brake fluid pressure. A drive force transmission mechanism for transmitting a drive force of the motor to the piston includes a nut 80c that rotates by the rotation drive force of the motor, and a ball screw shaft 80a that is engaged with the nut 80c so as to be moved axially and presses the piston. A pin 220 for stopping the rotation of the ball screw shaft 80a is arranged in the ball screw shaft 80a. A sleeve 210 having a sliding groove 211 for movably supporting the pin 220 with respect to the axial direction of the ball screw shaft 80a is disposed in a cover 173 of a housing 171 housing the drive force transmission mechanism. <P>COPYRIGHT: (C)2013,JPO&INPIT |
