Patent ID: 8292043

Claim:
A disc brake apparatus constructed to transmit a torque from a first torque transmission part of a brake pad to a first torque receiving part of a torque member at the time of normal braking of a disc rotor and transmit a torque from a second torque transmission part of the brake pad to a second torque receiving part of the torque member at the time of reverse braking of the disc rotor; the disc brake apparatus including switching holding means for holding the disc brake apparatus in a first contact state where the first torque transmission part of the brake pad abuts against the first torque receiving part of the torque member along with an operation for normal braking of the disc rotor, and switching the disc brake apparatus to and holding a second contact state where the first torque transmission part of the brake pad is moved away from the first torque receiving part and the second torque transmission part of the brake pad abuts against the second torque receiving part of the torque member along with an operation for reverse braking of the disc rotor; wherein the switching holding means includes a spring piece provided with at least one of first and second pad retainers respectively attached to the first and second torque receiving parts of the torque member, and an engaging projection provided with the brake pad so as to correspond to the spring piece; and wherein the spring piece rides over the engaging projection by a sloping engagement, so as to selectively bias the engaging projection toward the first torque receiving part or second torque receiving part, thereby switching the disc brake apparatus to and holding the first or second contact state.
