A brake device includes a hub (2); a wheel (4); a disc rotor (3) arranged between the hub (2) and the wheel (4); a fixing portion (5) that fixes the hub (2), the disc rotor (3), and the wheel (4) together by being inserted into a hub through-hole (23), a rotor through-hole (34), and a wheel through-hole (42); a hub-side connecting portion (25; 8) that connects the hub (2) and the disc rotor (3) together with the hub (2) separated from the disc rotor (3), by abutting against a hub-side end portion (34a) of the disc rotor (3), which defines the rotor through-hole (34); and a wheel-side connecting portion (45; 9) that connects the disc rotor (3) and the wheel (4) together with the disc rotor (3) separated from the wheel (4), by abutting against a wheel-side end portion (34b) of the disc rotor (3), which defines the rotor through-hole (34). |

1. A brake device comprising:
a hub in which a hub through-hole is formed, wherein the hub comprises a rotor-side fastening surface of the hub; a wheel in which a wheel through-hole is formed, wherein the wheel comprises a rotor-side fastening surface of the wheel; a disc rotor in which a rotor through-hole is formed, wherein the disc rotor comprises a hub-side fastening surface and a wheel-side fastening surface, and wherein the disc rotor is arranged between the hub and the wheel; a fixing portion that fixes the hub, the disc rotor, and the wheel together by being inserted into the hub through-hole, the rotor through-hole, and the wheel through-hole; a hub-side connecting portion is positioned between the hub and the disc rotor, and connects the hub and the disc rotor together with a gap formed between the rotor-side fastening surface of the hub and the hub-side fastening surface, the hub-side connecting portion abutting against a hub-side end portion of the disc rotor, which defines the rotor through-hole; and a wheel-side connecting portion positioned between the disc rotor and the wheel, the wheel-side connecting portion integrally formed on the wheel or the wheel-side connecting portion formed separately from the wheel, and the wheel-side connecting portion configured to connect the disc rotor and the wheel together with another formed between the rotor-side fastening surface of the wheel and the wheel-side fastening surface so that the rotor-side fastening surface of the wheel is separate from the wheel-side fastening surface, while the wheel-side connecting portion abuts against a wheel-side end portion of the disc rotor, which defines the rotor through-hole. |
