Abstract

A brake caliper according to this disclosure is, for example, equipped with: a body having a pair of side walls arranged with a gap therebetween, a peripheral wall running between the pair of side walls, wherein the pair of side walls and the peripheral wall enclose the peripheral edge portion of a disk rotor from the outside of the disk rotor in the radial direction; brake pads positioned between the side walls and the disk rotor; pistons that are supported by the side walls and that press the brake pads toward the side surfaces of the disk rotor by means of applied hydraulic pressure; and a shaft that supports the brake pads and passes through an opening provided in the side walls. The opening includes a retaining part that retains the shaft in the circumferential direction at two contact points separated from each other along the edge of the opening.

Claims

1. A brake caliper comprising:

a body which includes a pair of side walls disposed with a gap therebetween and a peripheral wall running between the pair of side walls, and in which the pair of side walls and the peripheral wall enclose a peripheral edge portion of a disk rotor from an outside of the disk rotor in a radial direction;

brake pads positioned between the side walls and the disk rotor;

pistons that are supported by the side walls and that press the brake pads against the side surfaces of the disk rotor by means of applied hydraulic pressure; and

a shaft that supports the brake pads and passes through an opening provided in the side walls,

wherein the opening includes a retaining part that retains the shaft in a circumferential direction of the disk rotor at two contact points separated from each other along an edge of the opening.

2. The brake caliper according to claim 1,

wherein the opening includes a narrow part as the retaining part, of which a width is narrower toward one side in the circumferential direction.

3. The brake caliper according to claim 1, further comprising:

an elastic member that presses the shaft against an inside or an outside of the edge of the opening in the radial direction,

wherein the retaining part is provided on a side of the edge of the opening where the elastic member presses the shaft.

4. The brake caliper according to claim 2, further comprising:

an elastic member that presses the shaft against an inside or an outside of the edge of the opening in the radial direction,

wherein the retaining part is provided on a side of the edge of the opening where the elastic member presses the shaft.
