A motor includes a bearing mechanism, a stationary unit including a stator arranged radially outwards of the bearing mechanism, and a rotary unit supported by the bearing mechanism at the upper side of the stationary unit for rotation about a center axis with respect to the stationary unit. The rotary unit includes a substantially cylindrical closed-top rotor yoke having a cover portion arranged to cover the stator. The bearing mechanism includes a substantially cylindrical closed-bottom bush formed by a press work, a sleeve fixed inside the bush and provided with an upper portion protruding beyond the bush and a shaft inserted into the sleeve. An upper end of the bush is lower than or flush with an upper end of the stator in a direction parallel to the center axis.
