A brushless motor includes a stationary unit and a rotary unit rotatably supported with respect to the stationary unit. The stationary unit includes an armature and a base member arranged to support the armature. The rotary unit includes a magnet, a hub made of a magnetic material and a rotor yoke made of a magnetic material. The armature includes a plurality of coil patterns arranged along a circumferential direction. The hub includes an inner lower surface, an outer lower surface and a recess portion. The recess portion is arranged between the inner lower surface and the outer lower surface and depressed upward. At least a portion of the magnet is accommodated within the recess portion. At least one of the inner lower surface and the outer lower surface is positioned above a lower surface of the magnet.
