Abstract:
A vehicular disk brake, comprising:a disk rotor; a caliper bracket fixed to a vehicle body on one side of said disk rotor; a caliper body having an acting portion and a reacting portion which are disposed opposite to each other in the both sides of said disk rotor, and a bridge portion coupling said acting portion and said reacting portion in such a manner as to stride over the outside of the disk rotor, said reacting portion of said caliper body having a protrusion or a fitting hole; a pair of slide pins provided in both ends of said caliper body in a radial direction of said disk rotor so that said caliper body is movably supported in an axial direction of said disk rotor; and a pair of friction pads oppositely disposed between said acting and reacting portions of said caliper body in such a manner that said disk rotor is intervened therebetween, said friction pad on a reacting portion side having one of said protrusion or said fitting hole so as to fit with said reacting portion of said caliper body, wherein the braking torque generated in the friction pad of the reacting portion side in the direction in which a vehicle travels forward is rotatably supported and is transmitted directly to said caliper bracket, the braking torque generated in said friction pad on an acting portion side in the direction in which the vehicle moves backward and forwards is rotatably supported by said caliper bracket, and the braking torque generated in said friction pad on the reacting portion side in the direction in which the vehicle moves backward is rotatably supported by said reacting portion of said caliper body by fitting said protrusion to said fitting hole.
