Abstract

A disc brake device is provided with a first pressing member disposed between a caliper and a pair of brake pads. The first pressing member has: a base section mounted to the caliper; a pair of plate spring sections extending from the base section toward one circumferential side of a disc rotor and toward the pair of brake pads and pressing the pair of brake pads inward radially; and an extension section extending from the base section toward said one circumferential side and supported by the caliper from the outside radially of the disc rotor.

Claims

1. A disc brake device comprising:

a caliper;

a disc rotor rotating with respect to the caliper;

a pair of brake pads positioned in the axial direction of the disc rotor with the disc rotor interposed therebetween;

a pressing portion disposed on the caliper and pressing the pair of brake pads toward the disc rotor;

an inner supporting portion disposed in each of the inner parts of the pair of brake pads in the radial direction of the disc rotor;

an outer supporting portion disposed in each of the outer parts of the pair of brake pads in the radial direction;

an inner spindle supported by the caliper and supporting the inner supporting portion of each of the pair of brake pads;

an outer spindle supported by the caliper and supporting the outer supporting portion of each of the pair of brake pads to make it possible to oscillate the pair of brake pads around the inner spindle; and

a first biasing member positioned outside the pair of brake pads in the radial direction and interposed between the inner surface of the caliper in the radial direction and the outer surface of the pair of brake pads in the radial direction,

wherein the first biasing member includes

a base portion attached to the caliper,

a pair of spring portions extending from the base portion in one of the circumferential directions of the disc rotor and extending toward the pair of brake pads and pressing the pair of brake pads inward in the radial direction, and

an extension portion extending from the base portion in one of the circumferential directions and supported by the caliper from the radial outside of the disc rotor.

3. The disc brake device according to claim 1, wherein the caliper has a restricting portion that supports the extension portion in the axial direction.

4. The disc brake device according to claim 1, wherein the spring portion has a curved portion which contacts the brake pad.

5. The disc brake device according to claim 1, wherein the spring portion has a bent portion between the base portion and a contact portion between the base portion and the brake pad.

8. The disc brake device according to claim 1, comprising a second biasing member which is disposed separately from the first biasing member and presses the outer spindle inward in the radial direction.

9. The disc brake device according to claim 1, wherein the caliper has a pair of facing portions spaced apart from each other in the axial direction and a connecting portion connecting the pair of facing portions,

the base portion is attached to the connecting portion.
