Embodiment Construction

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

[0037] Figures 2 to 8 Exemplary embodiments of the present invention are shown. The disc brake caliper 5a in the embodiment is used in a state that the disc brake caliper 5a is on the rotor 2 rotating together with the wheel (refer to Figure 10 ) above the perimeter is arranged as a bridging state. The caliper 5a is integrally formed of an aluminum alloy material, such as A6061 material. The caliper 5a includes along the axial direction of the rotor 2 (in figure 2 and 4 in the up-down direction, in image 3 In is the front-to-back direction, in Figure 5 in the up-down direction of the slope, and in Image 6 The outer body portion 3a and the inner body portion 4a arranged on both sides in the inclined left and right direction, and the surrounding direction for the two body portions 3a and 4a (in Figures 2 to 4 in the left-right direction, in Figure 5 in the tilted...

Abstract

After electroless nickel plating on the rotor side surface (10) of the caliper (5a) made of aluminum alloy and the opposite surface (11) arranged in the opposite side of the rotor side surface, the two surfaces (10, 11) Nickel-tungsten alloy plating. Then, only the rotor side surface (10) is plated with gold. Therefore, the reflectance of the rotor side surface (10) to incident light is higher than the reflectivity of the opposite surface (11) to incident light.

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] Figure 10 Such an opposed-piston disc brake described in JP-U-05-027364 is shown. 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 ...
