A moving magnetic field is generated by supplying a current to the coil of 0 and moving the supply destination of the supplied current, and the moving element 11 is moved.
Is repelled and sucked, the traveling body 4 floats along the traveling path 3. Since the intimidating object 14 fixed to the traveling body 4 has the voice generator A built therein, the vibration switch 17 senses the start of traveling and turns on the power of the voice generator A to activate the voice synthesis IC. Then, the pre-stored bark of the dog is output from the speaker 16, so that the running body 4 runs at high speed on the running path 3 as if the dog barking.

Further, when the traveling body 4 traveling on the traveling path 3 approaches the end portion of the traveling path 3, the engaging piece 19 provided on the traveling body 4 makes the first engaging member provided on the traveling path 3. The intimidating object 14 is forcibly rotated by hitting the mating shaft 20.
The intimidating object 14 abuts the second engaging shaft 21 and is prevented from rotating, and the direction change of the intimidating object 14 is completed. In this way, the orientation of the traveling body 4 is changed by the engagement piece 19 of the traveling body 4 hitting the engagement shafts 20, 20, and when the vehicle travels back and forth on the traveling path 3, the unnaturalness of traveling backward is eliminated. You can

As described above, when the bird-beast repelling device 1 of the present invention senses the approach of the birds-and-beasts 2, the traveling body 4 imitating a dog runs in the area 8 while barking. Run away from. Since the traveling body 4 is not driven by a motor and wheels, it has little noise even when traveling at high speed and quietly approaches and barks, which is highly effective.
Moreover, since the threatening object 14 of the traveling body 4 can be exchanged instead of always operating, the bird and beast 2 cannot learn and the effect can be continued.
