摘要： Disclosed is a motor including a rotor body mounted on a shaft and a chucking mechanism body mounted on a rotor hub, which are coupled with an increased coupling force by changing a coupling structure of the rotor hub of the rotor body and the chucking mechanism body mounted on the rotor hub. The motor includes: a sleeve rotatably supporting a shaft; a rotor body having a rotor hub mounted on the shaft; and a chucking mechanism body having a boss with a through hole in which the rotor hub is insertedly coupled and a space part formed within the boss and providing an elastic force when the rotor hub is coupled. Because a force of restitution resulting from an elastic deformation of the boss provided in the chucking mechanism body can be increased through the space part, namely, because a pressing force applied to the rotor hub of the rotor body can be increased by the boss, the coupling force between the rotor hub of the rotor body and the boss of the chucking mechanism body can be increased and, in addition, the coupling force between the rotor hub of the rotor body and the boss of the chucking mechanism body can be further increased by the release preventing unit.
