ABSTRACT:
A cooling fan unit includes a hook groove locking a plurality of lead wires drawn out of a circuit board and being formed in a wall of a housing in a direction of drawing out the lead wires. The hook groove has a lead wire through path which extends substantially perpendicularly from an end edge of the wall of the housing and a lead wire guide which extends substantially perpendicularly from a bottom of the lead wire through path. At least two of the plurality of lead wires are crossed with each other between the hook groove and a connection portion of the circuit board with respect to the plurality of lead wires, so that at least one second lead wire inhibits displacement of a first lead wire, which is aligned closest to the lead wire through path out of the plurality of lead wires accommodated in the lead wire guide, to a direction of being disengaged from the lead wire through path.
