PROBLEM TO BE SOLVED: To suppress an installation space for installing a colliding object diving-in prevention device, and effectively use a space beneath a front part of a vehicle body frame.SOLUTION: A rotation shaft part 11 of a colliding object diving-in prevention device 10 includes a guide member 19 fixed on a shaft support member 16, and a stopper 20 supported by an arm part 17. A step part 29 is formed between a front region 27 and a rear region 26 of a side wall part 19b of the guide member 19. While a diving-in prevention member 12 heads to from a storage position to a developing position, a curve surface 20c of the stopper 20 of the rotation shaft part 11 slides on a slide part 28 of the rear region 26 of the side wall part 19b of the guide member 19, and the stopper 20 is guided by the slide part 28 to tilt to a developing position side together with the arm part 17. When the diving-in prevention member 12 exceeds the developing position, the stopper 20 moves downward by its own weight, and a rear surface 20a is engaged with a front surface of the step part 29 in the developing position.SELECTED DRAWING: Figure 6 |
