PURPOSE: A motor is provided to prevent deformation of a connection hook of a rotor case, by combining the connection hook to a jamming protrusion of a sleeve housing easily. CONSTITUTION: A rotor case(22) is fixed to a shaft(50) as being able to rotate. The rotor case includes a connection hook. The connection hook comprises a number of elastic pieces. A sleeve(52) supports the shaft. The sleeve is indented to the inner circumference of a sleeve housing(54). A jamming protrusion of the sleeve housing is combined to the connection hook of the rotor case. A spiral movement path is formed in the jamming protrusion of the sleeve housing.
