Under this regulation, in the conventional vehicle fixing device, the chain that restrains the vehicle may interfere with the vehicle cooling fan, which makes it difficult to fix the vehicle. In particular, when using another vehicle fixing device, it is necessary to move and appropriately move the vehicle fixing device. In the conventional vehicle fixing device, the weight of the device main body is heavy, so that it is difficult for a single worker to move or move under an environmental condition without a hoist.

  On the other hand, since the vehicle fixing device 1 of the present embodiment includes the casters 4 and the caster moving handles 5, the vehicle fixing device 1 can be moved to an arbitrary predetermined position efficiently in terms of work.
