Abstract
A brake apparatus has an actuator mechanism for bringing a friction member into tight contact with a braking member so as to obtain a braking force, the actuator mechanism including: a moving piezoceramic member which can be elongated/contracted along a direction in which the friction member is urged; a holder disposed between opposing ends of the friction member and the moving piezoceramic member to couple the friction member and the moving piezoceramic member; and members for selectively restraining movement of the moving piezoceramic element in a direction parallel to the direction in which it is urged with respect to a fixing member.
