Abstract:
1. A disk brake comprising: a mount member configured to be attached to a non-rotational portion of a vehicle over a disk, the mount member including a pair of pin insertion portions extending in a disk axial direction of the disk; a caliper supported by the mount member via slide pins so as to be slidably movable in the disk axial direction, the slide pins being fitted in the pair of pin insertion portions of the mount member; and at least a pair of frictional pads positioned at respective surface sides of the disk and attached so as to be movable relative to the mount member in the disk axial direction, the at least pair of frictional pads being configured to be pressed against the respective surfaces of the disk by the caliper, the mount member including: an inner-side torque receiving portion configured to receive a braking torque of the inner-side frictional pad, which is one of the pair of frictional pads at an inner side corresponding to a non-rotational portion side of the vehicle; an outer-side torque receiving portion configured to receive a braking torque of the outer-side frictional pad, which is the other of the pair of frictional pads at an outer side corresponding to an opposite side of the disk from the inner side; and a connection portion arranged to connect the outer-side torque receiving portion and the inner-side torque receiving portion, wherein the pin insertion portions are provided so as to outwardly protrude from an outer surface of the connection portion in a disk radial direction of the disk, wherein each of the pair of pin insertion portions includes a pin insertion hole and each of the pin insertion holes has a bottom of the pin insertion hole, which is internally formed as a bottomed hole, wherein the bottom of each of the pin insertion holes is positioned closer to the inner-side torque receiving portion than the outer-side torque receiving portion is to the inner-side torque receiving portion, and wherein each of the pin insertion portions is disposed on the mount member such that a line connecting the axes of the pin insertion portions is located outwardly of the periphery of the disk in the radial direction of the disk.
