CALIPER BODY FOR VEHICULAR DISC BRAKE

A caliper body formed by selectively assembling either one of a radial-mount vehicle-body-side-opposing caliper half-body and an axial-mount vehicle-body-side-opposing caliper half-body to a vehicle-body-side caliper half-body, wherein: a hydraulic fluid introduction hole for introducing a hydraulic fluid into a cylinder hole from a joint surface toward a bottom portion side of the cylinder hole is formed in each of a vehicle-body-side caliper half-body 5, a radial-mount vehicle-body-side-opposing caliper half-body 6, and the axial-mount vehicle-body-side-opposing caliper half-body; the introduction hole formed in the radial-mount vehicle-body-side-opposing caliper half-body 6 and the introduction hole formed in the axial-mount vehicle-body-side-opposing caliper half-body each communicate with the introduction hole formed in the vehicle-body-side caliper half-body 5 at the joint surfaces; and either one of the radial-mount vehicle-body-side-opposing caliper half-body 6 and the axial-mount vehicle-body-side-opposing caliper half-body can be selectively assembled to the vehicle-body-side caliper half-body 5 by being joined thereto via the respective joint surfaces.
