To compatibly achieve towing strength and crushing property, regardless of low cost and light weight, regarding a towing hook mounting structure freely attaching/detaching a towing hook to/from a towing hook mounting member at an end part of a vehicle body by screwing.

The towing hook mounting member 18 for attaching/detaching the towing hook 22 to/from an external part of the vehicle body is fixed to a bumper reinforce side wall surface 12-1 of a crash box 12, and is directly non-fixed to a side member side. A steel wire 30 connects the towing hook mounting member 18 to the side member side. The steel wire 30 transmits tensile load by the towing hook 22 to the side member side but is free in a collision direction. When the bumper reinforce 14 and the crash box 12 are crushed during a collision, the towing hook mounting member 18 can be retreated via an escape hole 28 on the side member side.
