Abstract:
1. An electric brake comprising: a caliper having provided therein a motor, a rotary-linear motion conversion mechanism for converting rotation of the motor to a linear motion and a piston adapted to press a brake pad against a disc rotor according to a force transmitted from the rotary-linear motion conversion mechanism and thus generate a braking force; and a parking brake mechanism accommodated in a housing, the parking brake mechanism including an engaging structure capable of being engaged with an associated-movement portion which rotates in association with the motor, and a bias device for biasing the engaging structure in a direction for disengagement of the engaging structure from the associated-movement portion, the parking brake mechanism being capable of exerting a parking brake function through engagement and disengagement of the engaging structure relative to the associated-movement portion, the disengagement of the engaging structure being effected by temporarily rotating the associated-movement portion in a braking direction such that a braking force is generated when the engaging structure is engaged with the associated-movement portion to thereby move the engaging structure in the direction for disengagement under a biasing force of the bias device, wherein: a force-receiving portion is provided on a side of the associated-movement portion, the force-receiving portion being adapted to rotate the associated-movement portion in the braking direction upon receiving a force in the braking direction to thereby enable the disengagement of the engaging structure relative to the associated-movement portion under the biasing force of the bias device; and the housing includes an opening through which a force-applying member is inserted, the force-applying member being manually operable from an outside of the housing to thereby apply, to the force-receiving portion, a force in the braking direction such that the associated-movement portion is rotated in the braking direction, the opening being provided such that the outside of the housing is communicated with an inside of the housing.
