Abstract:
1. A disk brake comprising: a caliper disposed to extend over an outer periphery of a disk in a disk axial direction, the disk being rotatable relative to a stationary part of a vehicle; a piston provided at at least one side of the caliper in the disk axial direction; a pair of friction pads that are pressed against both sides of the disk by the piston; and a pressing mechanism provided between the piston and a friction pad of the pair of friction pads that is disposed between the piston and the disk, the pressing mechanism pressing the friction pad at a center in a disk circumferential direction of the piston when the piston starts to press the friction pad; wherein the pressing mechanism presses the center in the disk circumferential direction of the friction pad at at least two positions along a line segment in the disk radial direction, and wherein, when pressing force of the piston is in a low pressure range, the pressing force of the piston is transmitted to the friction pad through the pressing mechanism, and after the pressing force of the piston has exceeded the low pressure range, the pressing force of the piston is transmitted to the friction pad through a whole region in the disk circumferential direction of the piston.
