摘要： This caliper body of a disc brake for a vehicle prevents a mounting seat surface of a union bolt or bleeder screw from protruding outward from a caliper half body, and improves miniaturization and assembly characteristics. A disc outward-rotation-side end of a bridge half body 6c of an anti-vehicle body-side caliper half body 6 is provided with union holes 18 that open to a disc outward-rotation-side end surface 6g and communicate with a second working fluid introduction hole 16. A mounting seat surface 6h of a union bolt 19 is formed on the disc outward-rotation-side end surface 6g of an opening outer periphery of the union holes 18. A bleeder hole 12 that opens to an outer end surface 5g in the disc radial direction and communicates with a first working fluid introduction hole 11 is provided on the disk outward-rotation- side of a bridge half body 5c of a vehicle body-side caliper half body 5 and to a disc radial direction outer end. A mounting seat surface 5h of a bleeder screw 13 is formed on the disc radial direction outer end surface 5g of an opening outer periphery of the bleeder hole 12.

摘要： A disc brake for a vehicle capable of suppressing uneven abrasion of a lining of a friction pad depending on the rigidity of a caliper body and the material of the lining of the friction pad and capable of easily changing an operation feeling. In this disc brake for a vehicle, an inlet-side torque transmitting member 7 for receiving a braking torque of a friction pad 4 and an outlet-side torque transmitting member 8 are each mounted to a friction pad storage portion 3g of a caliper body 3. A first torque transmitting portion 7a of the inlet-side torque transmitting member 7 and a second torque transmitting portion 8a of the outlet-side torque transmitting member 8 are formed so that a thickness (T1) of the first torque transmitting portion 7a in the disc circumferential direction and a thickness (T2) of the second torque transmitting portion 8a in the disc circumferential direction differ from each other. The friction pad 4 is arranged so that the center of the friction pad 4 is offset from the center of the caliper body 3 in the disc circumferential direction.

摘要： The present invention provides a vehicle disc brake with increased ease of assembly of a pad spring. A caliper body has a locking groove 3p formed on the inside in the disc radial direction of a forward-travel disc run-in side surface of a ceiling opening 3f, the locking groove 3p locking a pad spring 5. The pad spring 5 comprises: a curved piece 5a abutting against the inside in the disc radial direction of a hanger pin 13 for hanging a friction pad 4; a run-in side pad spring-back part 5b extending from the curved piece 5a to the forward-travel disc run-in side and pressing the friction pad 4 inward in the disc radial direction; a run-out side pad spring-back part 5c extending from the curved piece 5a to the forward-travel disc run-out side and pressing the friction pad 4 inward in the disc radial direction; and a locking piece 5d provided at the tip of the run-in side pad spring-back part 5b, and locked in the locking groove 3p.

摘要： A disc brake pad (3a, 4a) which is supported by a pair of pins (11c, 11d) to a pad support member (2a) so that the disc brake pad (3a, 4a) is movable in an axial direction, include a lining (36) and a back plate (37) supporting a back surface of the lining (36). The back plate (37) includes a clip insertion portion (45a) where part of a pad clip (20a) is inserted in the axial direction, at an intermediate portion of a radially outer side portion in a circumferential direction, includes pin insertion portions (48a, 48b) where the pins (11c, 11d) are respectively inserted in the axial direction, at both sides of the radially outer side portion in the circumferential direction with the clip insertion portion (45a) located therebetween. The clip insertion portion (45a) includes, on a radially outer side portion of an inner peripheral surface thereof, a pressed surface (46) where a pressing force directed radially outward is applied from the pad clip (20a)
