Cover coupling structure

A cover coupling structure comprising:

• a coupling groove that is provided to an elongated shaped tonneau cover apparatus including a tonneau cover for covering a vehicle luggage compartment, the coupling groove comprising a coupling portion coupled to one end of a sheet-form front cover provided between a vehicle seat and the tonneau cover apparatus, and an opening portion that is open to the outer peripheral side of the tonneau cover apparatus and is in communication with the coupling portion and is set with a smaller height dimension than the height dimension of the coupling portion;
• an anchor portion provided to the one end of the front cover and coupling the one end of the front cover to the coupling portion by being inserted inside the opening portion and anchoring to the coupling portion;
• and
• a resiliently deformable portion that is formed at the anchor portion so as to be resiliently deformable, anchors the anchor portion to the coupling portion by engaging with the coupling portion, and is set with an external profile dimension along a direction orthogonal to a first face of the front cover that is larger than the height dimension of the opening portion when the resiliently deformable portion has been resiliently deformed.
