Embodiment Construction

[0036] Exemplary embodiments of the present invention are described with reference to the drawings.

[0037] 2 to 8 show exemplary embodiments of the invention. The disc brake caliper 5a in the embodiment is used in a state where the disc brake caliper 5a is arranged in a bridging state over the periphery of the rotor 2 (refer to FIG. 10 ) rotating together with the wheel. The caliper 5a is integrally formed of an aluminum alloy material, such as A6061 material. The caliper 5a includes an axial direction along the rotor 2 (a vertical direction in FIGS. 2 and 4 , a front-rear direction in FIG. 3 , an oblique up-down direction in FIG. 5 , and an oblique left-right direction in FIG. 6 ). The outer body portion 3a and the inner body portion 4a arranged on both sides, and the surrounding direction for the two body portions 3a and 4a (left-right direction in FIGS. , and in FIG. 6 is an inclined up and down direction) a pair of coupling portions 6, 6 that couple the two end portion...

Abstract

After chemical nickel plating has been applied onto a rotor-side surface 10 of a caliper 5a made of aluminum alloy and an opposite surface 11 disposed in an opposite side of the rotor-side surface, nickel-tungsten alloy plating is applied onto these both surfaces 10, 11. Then, gold plating is applied onto only the rotor-side surface 10. As a result, a reflectance to incident light on the rotor-side surface 10 is made higher than a reflectance to incident light on the opposite surface 11.

Description

technical field [0001] The present invention relates to a disc brake caliper installed in a disc brake for braking a vehicle such as an automobile, and a method of manufacturing the disc brake caliper. Background technique [0002] In order to brake an automobile, disc brakes are widely used. In braking by a disc brake, a piston presses a pair of pads arranged on both sides in the axial direction of a rotor that rotates with a wheel against both sides of the rotor. As such disc brakes, disc brakes of various structures are known. A stable braking power can be obtained from an opposed-piston disc brake in which pistons are disposed on both sides of a rotor in a state facing each other. Therefore, such opposed-piston disc brakes are increasingly used recently. [0003] FIG. 10 shows an opposed-piston disc brake of the type described in JP-U-05-027364. In an opposed-piston disc brake 1 , a caliper 5 consisting of an outer body 3 and an inner body 4 is provided in a position...
