摘要： A waterproof fan includes: a rotor including a rotating blade capable of rotating about a rotation axis; a stator including a plurality of stator cores extending in a radial direction relative to the rotation axis, and a winding wound around each of the stator cores; a frame including a housing space opening toward one side of the rotation axis; a circuit board electrically connected to the winding and housed in the housing space; a waterproofing resin portion covering the stator and the circuit board to block the opening of the housing space; and a positioning member provided in the housing space and configured to position the circuit board at a position away from an inner wall of the housing space.
