In an opposed-piston disc brake caliper, a pair of reinforcement bridge portions, which are inclined relative to an axial direction, are provided on outside of a rotor in a radial direction of the rotor so as to define corner opening portions in an opening portion which is defined by an inner body portion, an outer body portion, and an entry-side connection portion and an exit-side connection portion connecting the inner body portion and the outer body portion. A torque receiving portion of one of the entry-side torque receiving portion and the exit-side torque receiving portion is exposed toward an outside in the radial direction via the corner opening portions. |

1. An opposed-piston disc brake caliper comprising:
an inner body portion, provided so as to face an inner-side surface of a rotor that rotates along with a wheel, and including an inner cylinder which opens toward the inner-side surface of the rotor; an outer body portion, provided so as to face an outer-side surface of the rotor, and including an outer cylinder which opens toward the outer-side surface of the rotor; an entry-side connection portion and an exit-side connection portion, provided on outside of the rotor in a radial direction of the rotor, and connecting both end portions of the inner body portion to both end portions of the outer body portion in a circumferential direction of the rotor; an entry-side torque receiving portion and an exit-side torque receiving portion, configured to bear torque which is applied to a pair of pads when a brake is applied, while the pair of pads is supported so as to be displaced in an axial direction of the rotor with the rotor being interposed therebetween; and an opening portion, passing in the radial direction through a region surrounded by both the inner body portion and the outer body portion and both the entry-side connection portion and the exit-side connection portion, wherein a pair of reinforcement bridge portions, which are inclined relative to the axial direction, are provided on the outside of the rotor in the radial direction so as to define corner opening portions in the opening portion which are divided off from other portions of the opening portion, one of the reinforcement bridges bridges a gap from an axial intermediate portion of an inner end edge of at least one connection portion of the entry-side connection portion and the exit-side connection portion, the inner end edge being defining a circumferential end portion of the opening portion, to a portion on the one connection portion side of the inner body portion in the circumferential direction where the portion is positionally aligned with the inner cylinder, the other of the reinforcement bridges bridges a gap from the axial intermediate portion of the inner end edge of the one connection portion to a portion on the one connection portion side of the outer body portion in the circumferential direction where the portion is positionally aligned with the outer cylinder, and wherein a torque receiving portion of one of the entry-side torque receiving portion and the exit-side torque receiving portion is exposed toward the outside in the radial direction via the corner opening portions. |
