Abstract
A keyless rotation transfer unit may include a spline forming a pulley coupling force between an inner circumference of a shaft hole of a pulley and an outer circumference of a keyless shaft end forming one end of a shaft, with the keyless shaft end inserted into the shaft hole, and a flange nut screw-fastened to the keyless shaft end coming out of the shaft hole and forming a screw fastening force to press one surface of the pulley. In particular, the screw fastening force forms a shaft fastening force that causes a bearing to pressurize the other surface of the pulley, the bearing is coupled to the keyless shaft end and located at the rear of the pulley, and the flange nut forms a pulley holding force using the screw fastening force and the shaft fastening force.
