By fixing e, the rotary blade 2 is rotatably attached to the upper portion of the machine body 3.

A battery 5 such as a lightweight lithium battery is housed and attached to a body 3 at the center of rotation of the rotary blades 2 such as a light emitting diode which emits light by using the battery 5 as a power source. The light emitter 7 is attached so that the light emission can be seen from below.

FIG. 2 shows in detail an example of the connecting structure of the battery housing 6 and the light emitting body 7 such as a light emitting diode. The battery housing 6 is made of plastic or the like.
It is divided and formed so as to be detachable, and the battery housing portion 6a is adapted to be attached to the machine body 3 by screwing or an adhesive agent, and the lid portion 6b is detachably attached to the battery housing portion 6a. Has become.

On the inner surface of the battery housing portion 6a, the electrode 6c of the stored battery 5 is in contact with the electrode 6c and one lead wire 7a of the light emitting body 7 such as a light emitting diode connected to the electrode 6c.
Is provided with a contact 6d into which the
+ Electrode 6 which the + pole of the stored battery 5 contacts on the inner surface of the
e and a light-emitting body 7 such as a light-emitting diode connected to this
A contact 6f to which the other lead wire 7b is inserted and connected is provided.

The lead wires 7a and 7b of the light emitting body 7 such as the light emitting diode are made to have different lengths, and when the lead wires 7a and 7b having different lengths are correctly inserted, the lead wires 7a and 7b are Since the contacts 6d and 6f are provided so as to be in contact with 7b, it is possible to eliminate the possibility that the polarities of the light emitting body 7 such as a light emitting diode are connected to the battery 5 by mistake.
