Abstract:
A disk brake, comprising:a carrier fixedly mounted on a non-rotational portion of a vehicle body;a caliper slidably supported relative to the carrier by fitting a sliding pin provided in one of the carrier and the caliper into a guide bore formed in the other of the carrier and the caliper; anda first friction member and a second friction member disposed at axially opposite sides of a disk, the first friction member being adapted to press one side of the disk according to a motion of a piston provided in the caliper, the second friction member being adapted to press the second friction member against the other side of the disk according to a sliding motion of the caliper relative to the carrier which occurs when the piston presses the first friction member,wherein the caliper comprises:a cylinder portion disposed at one side of the disk and having a cylinder bore, the piston being slidably provided in the cylinder bore;a bridging portion extending across an outer periphery of the disk along the axis of the disk;a claw portion connected to the cylinder portion through the bridging portion and disposed at the other side of the disk to press the second friction member;a first mounting portion extending from the cylinder portion toward an entrance side with respect to a rotation direction of the disk; anda second mounting portion extending from the cylinder portion toward an exit side with respect to the rotation direction of the disk,each of the first and second mounting portions having a distal end portion connected to the carrier through the sliding pin,the first and second mounting portions being formed such that, relative to the rotation direction of the disk a length of the first mounting portion is greater than a length of the second mounting portion so that the center of the cylinder bore is offset relative to the disk toward the exit side, and such that, with respect to a direction of the axis of the disk, flexural rigidity of the first mounting portion is higher than flexural rigidity of the second mounting portion.
