PURPOSE: A structure of a stepping motor is provided to reduce the number of components and a manufacturing cost by using an oilless bearing. CONSTITUTION: A structure of a stepping motor includes a bracket assembly(110), a housing(113), a bobbin assembly(120), a rotor assembly(130), and a cover assembly(140). The bracket assembly(110) is formed by installing oilless bearings at a left and a right sidewall of a bracket. The housing(113) is adhered on inside of the bracket assembly(110). The bobbin assembly(120) is used for forming a magnetic path by wiring coils around a yoke formed at the inside of the housing. The rotor assembly(130) is formed with a magnet and a shaft, which are rotated by the magnetic field of the bobbin assembly(120). The cover assembly(140) is formed with an end cover and an elastic member.
