A disk brake includes a retainer part of a pad retainer provided with an outside section, back section, and inside section. A pad rebounding section is formed by inclining the leading end of a strip, which extends in the disk rotor direction from the end of the inside section away from the disk rotor with an elastic loop section therebetween, toward the outside in the radial direction of the disk. During travel, a gap is formed between the inside section and the strip of the pad rebounding section, and when a lug piece moves inward, the pad rebounding section and the inside section come into contact with each other, the inside section is pressed against an inside surface in the radial direction of the disk, the back section is elastically deformed, and the elastically deformed back section presses the lug piece toward the center side of a caliper body.

1. A disk brake for a vehicle, comprising: a disk rotor;a caliper bracket to be secured to a vehicle body, the caliper bracket having a pair of caliper support arms striding an outer edge of the disk rotor in a disk shaft direction, the pair of caliper support arms extending along the caliper bracket, the pair of caliper support arms having U-shaped pad guide grooves formed by an outside surface in a radial direction of a disk, an inside surface in the radial direction of the disk, and a facing surface connecting the outside surface and the inside surface, the U-shaped pad guide grooves being provided so as to face each other;a pad retainer; anda pair of friction pads disposed so as to sandwich the disk rotor, the pair of friction pads each having a lug piece projecting from both sides of a back plate of each of the pair of friction pads, the lug piece being supported in the pad guide groove via the pad retainer,wherein the pad retainer includes a pair of retainer parts mounted in the pad guide grooves on both sides of the disk rotor, a coupling piece connecting the pair of retainer parts while striding the outer edge of the disk rotor, and a pad rebounding section biasing the lug piece toward the outside in the radial direction of the disk rotor,the retainer parts each include an outside section disposed along the outside surface in the radial direction of the disk of the pad guide groove, a back section disposed along the facing surface, and an inside section provided so as to be inclined from inside end sections in the radial direction of the disk of the back section toward the outside in the radial direction of the disk of the back section,the pad rebounding section is formed by inclining a leading end of a stripe extending toward the disk rotor via an elastic loop section bent like an arc toward the outside in the radial direction of the disk, the elastic loop section extending from an end of the inside section away from the disk rotor, toward the outside in the radial direction of the disk,the lug piece is biased by the pad rebounding section toward the outside in the radial direction of the disk during travel of a vehicle, the lug piece being disposed in the pad guide groove with a gap provided between the inside section and the pad rebounding section, andwhen the lug piece moves toward the inside in the radial direction of the disk, the pad rebounding section comes into contact with the inside section, the inside section is pressed against the inside surface in the radial direction of the disk, the back section is elastically deformed so as to warp toward the lug piece, and the lug piece is pressed toward a center of the friction pad by the elastically deformed back section.
