Patent ID: 6845852

Claim:
A vehicular brake apparatus comprising: a motor that is electrically driven to revolve a shaft thereof; a reduction portion for reducing a speed of revolution of the shaft of the motor at a predetermined near ratio; a movement conversion portion for converting the revolution, which has already been reduced in speed by the reduction portion, to a linear movement, and for pressing a friction member to a disc revolving integrally with a vehicle wheel for generating a braking force; and a press member located between the movement conversion portion and the friction member and having clutch members that can selectively contact a first contact portion provided in a linear movement portion as an output portion of the movement conversion portion or a second contact portion provided in an end portion of the shaft of the motor, the clutch members being located alone a circumferential direction of the shaft and deformable in an axial direction of the shaft; wherein the press member includes a female screw at a center portion thereof, and a male screw integrally fixed with the friction member at a side of the friction member opposite the disc, the male screw being screwed in the female screw.
