Abstract
An improved disc brake caliper housing structure including a cylinder portion which has a cylinder wall section formed with a cylinder having a cylinder bore, a reaction portion located opposite to the cylinder portion axially of the cylinder, and a bridging portion connecting the cylinder and reaction portions. The bridging portion has a cross section, taken perpendicularly to the axis of the cylinder, which is of substantially circular arc configuration along the periphery of a disc rotor, and the cylinder wall section which has a fan-shaped profile to which the circumferential wall of the cylinder is virtually inscribed, has openings spaced radially of the cylinder. The openings are formed between both ends of the circular arc of the bridging portion, and those two segments of the circumferential wall of an open end portion of the cylinder which are nearest to the both ends of the bridging portion radially of the cylinder. This caliper housing structure provides improvements in reducing the wall thickness of the bridging portion while preventing its cylinder bore from being deformed upon brake application.
