このような従来の構成では、羽根１ｏ１の取付。2. Description of the Related Art A conventional electric fan blade attachment device has a configuration as shown in FIG. In the figure, 101 is a blade having a boss portion 106, and 103 is a shaft of an electric motor 104 having a shaft pin 107 on the side surface and a threaded portion 102 at the tip. 106 inserts the boss portion 106 of the blade 101 into the shaft 103 and screws into the threaded portion 102;
This is a spinner for fixing the blades 101, and the blades of the electric fan are attached by the tightening force of the spinner 105.Problems to be Solved by the Invention In such a conventional configuration, the blades of the fan are attached by the tightening force of the spinner 105.

され、羽根２は電動機４に取付けられる。With the above configuration, the boss part 3 of the blade 2 is inserted into the shaft 6 of the electric motor 4, the key-shaped notch 1 provided in the boss part 3 is hooked on the shaft pin 6, and the blade 2 is slightly rotated. When the hand is released, the shaft 6 is pushed toward the electric motor 4 by the restoring force of the spring 7, the shaft pin 6 is locked in the notch 1, and the blade 2 is attached to the electric motor 4.
発明の効果
以上のように本発明によれば、羽根を電動機に挿入し、
切欠部をシャフトピンに引掛けるだけで、スプリングの
復元力によシ、簡単に羽根を取付けられ、非常に便利で
ある。また、スピンナーを使用しないためネジのゆるみ
による、羽根の振動。Effects of the Invention As described above, according to the present invention, a blade is inserted into an electric motor,
The blades can be easily attached by simply hooking the notch onto the shaft pin and using the restoring force of the spring, making it extremely convenient. Also, since a spinner is not used, the blades vibrate due to loosening of the screws.
脱落の恐れがなく非常に安全であシ、その実用的効果は
大きい。また、スピンナーを用いないため、コストの低
減、及びシャフト先端のネジ切シ加工の削減ができ、工
業的効果も大きい。It is extremely safe with no fear of falling off, and has great practical effects. In addition, since no spinner is used, it is possible to reduce costs and reduce the need for thread cutting at the tip of the shaft, which has great industrial effects.
