Disc brake

A disc brake of a floating type, comprising:

• an inner pad and an outer pad respectively located on opposite sides of a rotor rotatable with a wheel;
• a pressing device configured to press the inner pad and the outer pad against the rotor, and
• a housing mounted on a non-rotating member and holding the pressing device,
• wherein the pressing device comprises:
• a first pressing member movable toward the rotor;
• a second pressing member movable away from the rotor;
• and
• a frame comprising (i) a first side portion opposed to the second pressing member and (ii) a second side portion engaged with the outer pad and movable together with the outer pad in a direction parallel with a rotation axis of the rotor, and
• wherein the disc brake comprises a return spring provided between the frame and the inner pad,
• wherein one end portion and another end portion of the return spring extend respectively in directions substantially perpendicular to each other in front view,
• wherein the frame comprises a frame-side hole extending substantially in a radial direction of the rotor,
• wherein the inner pad comprises:
• a friction engageable member comprising a friction engageable surface frictionally engageable with the rotor;
• and
• a back board holding the friction engageable member,
• wherein the back board comprises a pad-side hole extending substantially in a direction orthogonal to the radial direction of the rotor,
• wherein the one end portion of the return spring is inserted in the frame-side hole and held by the frame, and
• wherein said another end portion of the return spring is inserted in the pad-side hole and held by the inner pad.
