Claims

[Scope of utility model registration request]

A disc rotor fitted in a rotary shaft to be braked so as to be movable in the axial direction, and a pair of fixing devices having threads cut in mutually opposite directions on the outside of a cylindrical part fixed on both sides of the disc rotor and extending concentrically to the rotary shaft. a screw, and a screw on the inside that engages with the screw; the screw is rotatably supported around the rotational axis via the screw; and the disk is formed at an end near the disk rotor at approximately right angles to the rotational axis. 1. A disc brake device comprising: a pair of movable screws having curved end surfaces; and a brake handle device capable of rotating the pair of movable screws simultaneously.
