DISK ROTOR AND CALIPER FOR DISK BRAKE DEVICE, AND DISK BRAKE DEVICE

PROBLEM TO BE SOLVED: To provide a disk rotor for a disk brake device capable of improving heat radiating performance by utilizing running air. SOLUTION: The disk rotor 12 is formed into a disk shape having a large-diameter hole 20 circularly notched in a central part thereof, and a surface of the disk rotor 12 is inclined so that the inner edge part 22 is positioned in one side of the outer edge part 21 in the shaft center 23 direction, and a slide-contact part 24 formed of a curved surface is formed between the outer edge part 21 and the inner edge part 22. A surface and a back surface of the slide-contact part 24 are formed into a slide-contact surfaces 27 and 28. The disc rotor 12 is concentrically arranged with front wheels 4 so that the inner edge part 22 is separated from the front wheels 4 more than the outer edge part 21. As a result, the slide-contact surface 27 can receive a lot of running air to improve heat radiating performance of the disk rotor 12. COPYRIGHT: (C)2005,JPO&NCIPI
