先端突出部を位置させることができる。 In the electric fan constructed as described above, when the electric motor 2 is operated, the rotor blades 3 are rotated and air is blown, and the fan is oscillated by reciprocating from side to side on the support portion of the neck piece 5. In addition, the connector 11
By fitting and supporting the cylindrical body 6, it rotates within the range of the elongated hole 7 provided in the cylindrical body 6,
Swing the blower at any position. This is what is called a double swing. Here, the spring body 2 is provided to engage with the recess 18 of the rib 17' of the connector 11.
0 acts to press the brake body 21 against the cylindrical body 6, but the pressing force is enough to allow rotation of the cylindrical body 6 in the circumferential direction. Further, the rib 1 of the coupling tool 11 is attached to the concave portion 22a of the sawtooth-like concave and convex portion 22 of the brake body 21.
Since the lower end portion of 7' is fitted, rotation of the brake body 21 and the coupling member 11 is prevented. Therefore, when double swinging is performed, the cylinder body 6 and the brake body 21 rotate while being in frictional contact with each other, so the coupling member 11 is prevented from rotating due to vibrations caused by the operation of the electric motor 2, for example. , and by repeating the rotational movement of the cylinder 6 and the connector 11 by the double swinging operation, the brake body 21 moves below the cylinder 6 and is not separated from the connector 11 and remains at a predetermined position. The head oscillation is made to occur. In order to prevent the spring body 20 from moving downward at the lower end of the rib 17', during assembly, force is applied to the lower end of the rib 17' to cause it to slightly elastically deform. The tip protrusion of the rib 17' can be positioned.

ある。 As explained above, in this invention, a spring body is provided at the fitting part of the coupling device and the cylinder body, and a brake body is provided for pressing the cylinder body by this spring body, and the spring body is provided in the coupling device. The rib has a recess for accommodating the brake body, and a rib whose lower end contacts the spring body and holds the spring body in the recess is integrally provided, and this rib is mutually engaged with the brake body. Since the rotation of the connector is restricted by the brake body, the connector does not rotate due to vibrations caused by the operation of the electric motor, and the spring body is prevented from rotating by the rib of the connector. Since the spring body and the brake body are prevented from coming off and held in a latched state in the recess, even after repeated use, the spring body and the brake body do not come off from the recess, and the blower can be swung at a predetermined position. Furthermore, since the spring body is prevented from coming off by the ribs, there is no need for special parts for preventing the spring body from coming off, and the structure can be simplified.
