In addition, when the air in the pneumatic cylinder 15 is discharged to the outside, the pneumatic cylinder 15 is retracted, the slider 13 is slid in a direction away from the ground, the stump 17 is spaced apart from the wheel (W) Can be.

The stump 17 may be inserted between the wheel W and the ground to prevent the vehicle from slipping. The stump 17 may be connected to the slider 13. For example, the stump 17 may include a connection member 171 and a stub member 172.

The connecting member 171 may be fixed to the slider 13. The connection member 171 may extend in one direction from the slider 13. The connecting member 171 may be at an angle with the pneumatic cylinder 15. The angle between the connecting member 171 and the pneumatic cylinder 15 can be changed by the tension or compression of the pneumatic cylinder 15. The angle formed by the connecting member 171 and the slider 13 may be adjusted. For example, the user may use the angle formed by the connecting member 171 and the slider 13 to allow the bottom surface of the holding member 172 to contact the ground based on the state in which the pneumatic cylinder 15 is fully tensioned. Can be adjusted.

The pinch member 172 may be fitted between the wheel W and the ground. The holding member 172 may have, for example, a shape that narrows toward the point where the wheel W abuts on the ground. The end of the retaining member 172 may be located near the point where the wheel W abuts the ground. The bottom surface of the retaining member 172 may be in surface contact with the ground.

The air injection line 19 may connect the pneumatic cylinder 15 and the air tank T.

The support member 21 may support the slider 13 in a state where the pneumatic cylinder 15 is compressed. The support member 21 may be rotatably connected to the guide 11. For example, the support member 21 may support the protrusion 131 of the slider 13.

The elastic body 31 may connect the support member 21 and the guide 11. In a state where the external force of the elastic body 31 is not applied, the elastic body 31 may set an initial distance between the support member 21 and the guide 11. For example, when the protrusion 131 of the slider 13 is positioned between the support member 21 and the guide 11, the distance between the support member 21 and the guide 11 may be greater than the initial distance. In this case, the elastic body 31 can press the supporting member 21 in the direction toward the guide 11, and the supporting member 21 can stably support the slider 13.
