To improve the absorbability of a collision energy by more axially compression-deforming a towing hook mounting part in a vehicle frame in a vehicle collision.
The towing hook structure has a front side hook member 14 where the upper part 14A is fixed to a front side member 10 (vehicle frame), and a rear side hook member 16 which composes the towing hook 12 with the front side hook member 14, where the upper part 16A which is fixed to the upper part 14A of the front side hook member 14 in the front side member 10 and the position separated to the rear side of a vehicle, and relatively deformably composed of the front side hook member 14 in axially compression-deforming of the front side member 10. Since the upper parts 14A, 16A are firmly fixed to the front side member 10, tow rigidity is sufficiently assured. Since the front side hook member 14 and the rear side hook member 16 are relatively displaced in axially compression-deforming of the front side member 10, the axial compression deformation is not hindered by the rigidity of the towing hook mounting part.
