Claims

[Scope of utility model registration request]

By reciprocating the transmission shaft, the drive gear rotated by the motor for driving the blower blades and the cover member of the gear housing housing the drive gear are selectively engaged and disengaged, thereby swinging the head of the fan. and a first secured portion provided on the driving gear;
The transmission shaft is supported by the second engaged portion provided on the lid member, the first and second retaining portions provided on the transmission shaft, and the support portion provided on the lid member, so that the transmission shaft can be moved back and forth. Due to the movement operation, the first engaging part engages with the first engaged part, and when reversed from this direction, the second engaging part engages with the second engaged part. A oscillation control device for an electric fan, comprising a leaf spring that is biased in a matching direction.
