Provided is a reversible fan that produces a current of air in both of a normal direction and a reverse direction, the reversible fan including: an impeller configured to be rotatable about a rotation axis; a motor configured to rotate the impeller; a base portion supporting the motor; a tubular frame housing the impeller, the motor, and the base portion; a spoke extending from an inner peripheral surface of the frame toward the rotation axis, the spoke supporting the base portion; and a holding portion configured to hold at least a part of a lead wire provided along the spoke to apply power to the motor, wherein the holding portion is provided with a housing space opening in the reverse direction and extending along the spoke.

A waterproof fan includes: a rotating blade configured to be rotatable about a rotation axis; a rotor including a permanent magnet; a stator including a plurality of stator cores located on an inner diameter side relative to the rotating blade, the plurality of stator cores extending in a radial direction relative to the rotation axis, and windings each wound around a respective stator core; a circuit board electrically connected to the windings; a waterproof cover including a first resin, the waterproof cover covering the circuit board; and a molded portion including a second resin, the molded portion covering at least the stator, the waterproof cover includes: a partitioning portion separating the windings from the circuit board; and a protruding portion protruding from the partitioning portion into a space between the windings, and gaps between the windings, and the partitioning portion and the protruding portion are filled with the second resin.

A motor unit includes a motor, a substrate, a motor case, a connector, and a restriction portion. In the motor, a rotor including a rotary shaft extending in an axial center direction rotates about an axial center of the rotary shaft as a rotation center. The substrate is provided with a circuit element constituting a drive circuit for driving the motor. The motor case houses the motor and holds the substrate. The connector includes a connection terminal directly connected to the substrate. The restriction portion restricts displacement of the connector with respect to the substrate by coming into contact with the connector.

Proposed are a blower for a ventilation seat having a warm-air-blowing function and a vehicular ventilation seat including the same. The blower moves air supplied to the vehicular ventilation seat. The blower includes a housing having an accommodation space formed therein and including an inlet receiving air and an outlet discharging air, a motor mounted in the housing, an impeller mounted in the housing and configured to be driven by the motor to move air, a printed circuit board mounted in the housing, and a heater mounted in the housing so as to be connected to the printed circuit board and configured to heat the air flowing through the housing.

A hermetic compressor includes a compressor shell, a terminal provided on the compressor shell, a terminal guard erected on the compressor shell and surrounding the terminal, and a terminal cover mounted to the terminal guard and covering the terminal.
