PURPOSE: To prevent a one-sided touch of a brake pad on a disc rotor by preventing the moment such as integrally rotating them around its rotational center from being exerted on a pair of upper and lower brake levers in a disc brake device. CONSTITUTION: A disc brake device is constituted in such a way that an extending part 20a of a link lever 20 is towed by a brake cable 24, and a pair of upper and lower brake levers 17 are rotated, and a disc rotor 12 of a traveling motor 10 is sandwiched and braked by a brake pad 19 arranged on a tip opposed surface of the brake levers 17. A regulating member 26 having a guide surface 26a is provide to regulate a center pin 22 being a mutually connecting part of the link lever 20 so as not to deviate from a straight line connecting its center and the center of a support pin 18 being the rotational center of the brake levers 17 at input time of operation force by the brake cable 24. |
