Claim:
1. A disk brake comprising: a floating caliper including a base portion which is slidably supported via a guide pin with respect to a tubular supporting portion of a support and a pair of pressing arms which extend from the base portion to positions where the pressing arms pinch a disk rotor from both sides of the disk rotor in an axial direction; a pair of brake pads provided in respective tip portions of the pressing arms so as to face side surfaces of the disk rotor; a driving piston provided on one of the pressing arms so as to drive one of the brake pads toward one of the side surfaces of the disk rotor; and a caliper return mechanism arranged in at least one of both end portions of the guide pin on a side opposite to a side of the driving piston so as to elastically bias the base portion slidably supported by the guide pin on the side opposite to the side of the driving piston.
