Abstract:
A motor includes a shaft, a bearing mechanism rotatably supporting the shaft, a cylindrical rotor main body fixed to the shaft, a rotor fan fixed to the shaft, an armature, and a housing. The bearing mechanism includes a first bearing above the rotor fan in the housing and facing the rotor fan in an up and down direction. The housing includes a first opening, a second opening, and a bearing holding portion. A cylindrical wind tunnel portion is outward of the rotor fan in a radial direction. An inner surface of the wind tunnel portion and the rotor fan face each other in the radial direction. An upper end portion of the inner surface of the wind tunnel portion and an outer surface of the bearing holding portion face each other in the radial direction.
