The outer circumferential surface comes into contact with an obstacle. However, since the outer circumferential surface of the protective member is sloped downward from the front side wall, the protective member acts as a warp, and the beam body and the protective member slide over the obstacle as one, causing an obstacle. You can overcome things. Therefore, the horizontal collision force caused by contact with an obstacle is alleviated, and deformation of the beam body is prevented.
次に、本発明の実施例を図面に基づいて説明する。 Next, embodiments of the present invention will be described based on the drawings.

次に、本実施例に係るアクスルビーム構造の作用を第3
図(a)〜(C)に基づいて説明する。Next, the effect of the axle beam structure according to this example will be explained in the third section.
This will be explained based on FIGS. (a) to (C).

で、塔乗者に大きな衝撃を与えることもない。As shown in FIG. 3(a), when the axle beam 21 comes into contact with an obstacle 11 that protrudes high on the road, the outer surface 24A of the protection member 24 comes into contact with the obstacle 11 first. Then, the axle beam 21 touches the outer peripheral surface 2 of the protection member 24.
It slides like a sled on the outer surface of the obstacle using 4A as a sliding surface, and can jump over the obstacle 11 as shown in FIGS. 3(b) and (C). In this way, when the axle beam 21 comes into contact with an obstacle, it can slide on the obstacle and avoid a collision with the obstacle. A large horizontal collision force as indicated by P does not act, and deformation of the axle beam 21 is prevented. Further, since a large horizontal collision force P does not act on the axle beam 21, no large impact is given to the tower occupants.

ない。Note that when the axle beam 21 passes over the obstacle 11 while contacting the obstacle, the axle beam 21
However, if this axle beam push-up amount h (see FIG. 3(b)) is small, the shock absorbers 8. 8 absorbs the upward force, and the impact force in the vertical direction due to the axle beam 21 contacting the obstacle 11 is not transmitted to the vehicle body. Also, if the amount of push-up is large, the shock absorber with coil spring 8.8 will not be able to absorb the amount of push-up, and the vehicle body will also be pushed upward.However, the shock absorber with coil spring 8.
.. 8, the impact force in the vertical direction caused by the axle beam 21 coming into contact with the obstacle 11 is relaxed and transmitted to the vehicle body, so that it does not cause a large impact to the occupants.
