    Abstract: A trunk structure for a vehicle improves retainment performance of goods to a vehicle body in a cargo net, and improves flexibility of the layout of a trunk board. The trunk structure includes a trunk board, a hook member attached to the trunk board to which a cargo net covering goods can be locked, an interior member which constitutes an inside surface of a trunk, and an engaged portion of the interior member which the hook member can engage, the engaged portion restraining movement of the trunk board in an up-down direction when the engaged portion is engaged with the hook member. The hook member is switchable between an engaged state where the hook member engages the engaged portion and a non-engaged state where the engagement is released, and retains the engaged state by locking the cargo net to the hook member.
