To provide an inexpensive device for preventing bird injury by precisely driving a bird away for a long time, hardly allowing the bird to become accustomed thereto.
The bird injury-preventing device is constituted by installing a hitting device 14 and an illuminant 18 in an elevator 2 movable along a guide rail 1 installed in a transmission line tower T in the upper and lower direction. The hitting device 14 hits the guide rail 1 by engaging a hitting pin 16b with a cam 16a interlocked with a driven shaft 13 of the elevator 2 through a transmission mechanism 15. The illuminant 18 repeats blinks. The driving power required for the driving of the elevator 2 and the light-emitting action of the illuminant 18 is generated by a solar panel 19. The device can effectively threaten the bird by sound, vibration and light because the hitting device 14 hits and the illuminator 18 blinks while moving the elevator 2.
