The plug member closes the second hole.

Claims (20)

1 . A blower comprising:

a case having an opening;

an impeller disposed in the case;

a motor disposed in the case and configured to drive the impeller, the motor including a printed circuit board;

a grommet disposed in the case;

a wiring; and

a plug member,

wherein

the grommet includes first and second holes that communicate between an inside and an outside of the case via the opening,

the wiring is inserted into the first hole,

the plug member closes the second hole,

the plug member includes:

an insertion portion inserted into the second hole, and

a support portion having such a size as not to be inserted into the second hole and supporting the insertion portion,

the insertion portion is restricted from being pulled out of the second hole to the inside of the case by contact of the support portion with the printed circuit board, and

a length of the plug member in an axial direction of the second hole is longer than a distance from an inner surface of the grommet to an edge of the printed circuit board.

2 . The blower according to claim 1 , wherein (i) in a first state in which the insertion portion is fully inserted into the second hole, a space exists between the support portion and the printed circuit board, and (ii) the contact of the support portion with the printed circuit board occurs in a second state in which the plug member has been shifted toward the inside of the case and partially withdrawn from the second hole.
