  • Patent number: 8746418
    Abstract: Disclosed is a disc brake. The disc brake includes clip parts provided at inner portions of both side ends of a pair of pad plates and engaged with protrusions formed in the carrier and torsion pins fitted into the clip parts such that the clip parts are rotated between the pad plates upon a braking operation of the disc brake. Upon the braking operation, the pad plates push the carrier so that the clip parts are rotated about the torsion pins by the pad plates. Thus, strain energy of the carrier is absorbed through warpage deformation of the torsion pins, so that the carrier has sufficient strength even if an outer beam is removed.
