A reversible fan that produces a current of air in both of a normal direction and a reverse direction, the reversible fan having a front side and a backside comprising: a single impeller configured to be rotatable about a rotation axis, a plurality of blades being radially attached to the perimeter of the impeller; a motor configured to rotate the impeller, said front side of the fan being the side of the fan where wind is discharged when the motor rotates in a counterclockwise direction, where a direction pointing to the front side along a direction of a rotation axis is the normal direction, said back side of the fan being the side of the fan where wind is discharged when the motor rotates in a clockwise direction, where a direction pointing to the back side along the rotation direction is the reverse direction, and said motor being assembled in the impeller in such a manner as to be placed on the normal direction side relative the impeller; a base portion supporting the motor and being provided in such a manner as to cover the normal direction side of 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 having a flat cross-sectional shape extending in a direction substantially along the rotation axis; and a holding portion configured to hold at least a part of a lead wire to apply power to the motor and provided along the spoke, wherein the holding portion is formed in such a manner as to protrude in the direction intersecting the rotation axis from an end on the normal direction side of the spoke extending in direction along the rotation axis, and further extending in the reverse direction such that the holding portion has a convex shape facing in the normal direction side and such that the holding portion and a side surface of the spoke define a housing space having an opening in the reverse direction side and extending along the spoke. a single impeller configured to be rotatable about a rotation axis, a plurality of blades being radially attached to the perimeter of the impeller; a motor configured to rotate the impeller, said front side of the fan being the side of the fan where wind is discharged when the motor rotates in a counterclockwise direction, where a direction pointing to the front side along a direction of a rotation axis is the normal direction, said back side of the fan being the side of the fan where wind is discharged when the motor rotates in a clockwise direction, where a direction pointing to the back side along the rotation direction is the reverse direction, and said motor being assembled in the impeller in such a manner as to be placed on the normal direction side relative the impeller; a base portion supporting the motor and being provided in such a manner as to cover the normal direction side of 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 having a flat cross-sectional shape extending in a direction substantially along the rotation axis; and a holding portion configured to hold at least a part of a lead wire to apply power to the motor and provided along the spoke, wherein the holding portion is formed in such a manner as to protrude in the direction intersecting the rotation axis from an end on the normal direction side of the spoke extending in direction along the rotation axis, and further extending in the reverse direction such that the holding portion has a convex shape facing in the normal direction side and such that the holding portion and a side surface of the spoke define a housing space having an opening in the reverse direction side and extending along the spoke.
