Disc brake

A disc brake comprising:

• a caliper main body configured to have a pad assembling space that is disposed across over a disc rotor and opens toward an approximate middle thereof in a rotor radial direction and a connector part that is disposed to cross the pad assembling space in a rotor axial direction;
• a pair of brake pads configured to be disposed to be opposite to the disc rotor;
• and
• a pad spring configured to be engaged with the connector part by a pair of claw portions facing each other, to be installed on the caliper main body, and to bias the brake pads in a rotor rotational outlet direction and inward in the rotor radial direction,
• wherein the connector part is installed at a middle position of the pad assembling space in a rotor rotational direction, and is provided with a hole portion formed to be offset in the rotor rotational direction with respect to a middle position of the brake pads in the rotor rotational direction,
• wherein the pad spring has a symmetrical shape with respect to the center in a longitudinal direction thereof, and
• wherein the pad spring is configured such that at least one of the pair of claw portions is disposed in the hole portion, the pair of claw portions are engaged with the connector part, and a position of the pad spring is defined relative to the brake pads in a state in which the center of the pad spring in the longitudinal direction is offset in a rotor rotational direction with respect to the center of the brake pads in the rotor rotational direction.

A disc brake comprising:

• at least one pair of brake pads configured to be disposed to be opposite to a disc rotor;
• and
• a caliper main body configured such that the brake pads are disposed in a pad assembling space that opens toward an approximate middle thereof in a rotor radial direction, and the brake pads are locked so as to be capable of being pressed to the disc rotor,
• wherein the caliper main body includes:
• a pair of cylinder parts configured to be opposite to each other across the pad assembling space in which pistons configured to press the brake pads are housed;
• a pair of end-side connector parts configured to cross the disc rotor at ends in a rotor rotational direction of the pair of cylinder parts, to connect the pair of cylinder parts, and to face each other across the pad assembling space;
• and
• a connector part configured to be installed between the pair of end-side connector parts, to cross the pad assembling space in a rotor axial direction, and to connect the pair of cylinder parts,
• the disc brake further includes a pad spring configured to be engaged with the connector part, to be installed on the caliper main body, and to bias the brake pads inward in the rotor radial direction,
• wherein the connector part is installed at a middle position of the pad assembling space in a rotor rotational direction, and is provided with a hole portion formed to be offset in a rotor rotational direction with respect to a middle position of the brake pads in the rotor rotational direction, and
• the pad spring is configured;
• to have a symmetrical shape with respect to the center in a longitudinal direction thereof;
• and
• such that at least one of a pair of claw portions of the pad spring is disposed in the hole portion and is engaged with the connector part, a position of the pad spring is defined relative to the brake pads in a state in which the center of the pad spring in the longitudinal direction is offset in the rotor rotational direction with respect to the center of the brake pads in the rotor rotational direction.
