The stator is arranged radially outward of the bearing unit. The PCB includes through-hole portions, land portions and PCB fixing portions. The base member includes a stator holding portion arranged to hold the stator and a bearing holding portion arranged to hold the bearing unit. The rotary unit includes a shaft positioned radially inward of the bearing unit and a magnet opposed to a circumferential surface of the stator core. The through-hole portions are arranged along a circumferential direction of the PCB. At least a portion of the PCB axially overlaps with the bearing unit. The PCB fixing portions are arranged radially outward of the through-hole portions.
