Abstract: A resin composition for a friction material which is produced by a process including performing polymer blending of a phenol resin and a lignin; and a friction material including the resin composition. The resin composition for a friction material is useful as a binder in the friction material.

Abstract: A disc brake apparatus includes a boot including a fitting part. A slide pin is fixed to one of a support and a caliper and is slidably mounted to a guide hole formed in the other. Convex parts extending in a sliding direction of the slide pin are circumferentially arranged on an inner periphery of the fitting part. Concave recesses are respectively formed between the neighboring convex parts. Each of the convex parts is formed with at least one a low-height portion and a high-height portion in an axial direction of a rotor, respectively. Positions of the low-height portion and the high-height portion in a circumferential direction of the rotor are respectively different between the adjacent convex parts. The high-height portion has a height so as to contact the slide pin, and the low-height portion has a height so as not to contact the slide pin.

Abstract: A composite disc rotor includes a disc main body, a coupling bracket and coupling units. Each of the coupling units includes a bobbin, a clip and a coupling bolt. A head part of the bobbin includes a torque receiving portion inserted in the notch and a projection projected in a circumferential direction from an end of the torque receiving portion. A pipe part of the bobbin is extended from the head part and is fitted in a coupling through hole of the disc main body. The clip includes a connecting portion between the torque receiving portion and the notch and a pressing portion extended from the connecting portion between the head part and the coupling bracket. The coupling bolt is inserted into each of through hole of the bobbin to fix the coupling bracket to the coupling unit.

Abstract: There is provided a drum brake type electric parking brake apparatus includes an electric actuator unit, a backing plate and a knuckle. The electric actuator unit includes an electric motor and a decelerator, and expands a gap between one end portions of the brake shoes based on activation of the electric motor. The electric actuator unit is separately provided from the backing plate. The electric actuator unit is arranged at an inner-side surface of the knuckle, and the backing plate is arranged at an outer-side surface of the knuckle. The backing plate and the electric actuator unit are supported and fixed to the knuckle.

Abstract: There is provided a protection clip for a torque receiving part. The protection clip is fitted into a concave portion of a torque receiving part of a caliper body, into which a lug part of a brake pad of a disc brake is inserted. The protection clip includes first and second separation preventing claws. The first separation preventing claw is bent from an outer periphery-side wall surface of the concave portion toward an upper attaching surface of the torque receiving part, and is configured to be fitted into one of a pair of recesses formed over an opening of the concave portion. The second separation preventing claw is bent from a lower attaching surface of the torque receiving part toward the concave portion, and is configured to be fitted into the other of the pair of recesses.
