<p><P>PROBLEM TO BE SOLVED: To stabilize the behavior of a piston that is a driving member in a brake device. <P>SOLUTION: An inclined surface portion 50 is formed in a leg portion 32 of the piston which moves forward and backward in Z direction. An output roller unit 60 which contacts with the inclined surface portion 50 is provided on a backward side end portion 43 of a push rod which moves forward and backward in Y direction by the forward and backward movement of the leg portion 32. The output roller unit 60 includes a plurality of rollers 62. The plurality of rollers 62 are arranged in a direction along the inclination of the inclined surface portion 50, and provided on a frame 64 so that the rotating axes thereof are parallel to X direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
