Abstract

This vehicle luggage box structure comprises a header board constituting a vehicle-front-side wall surface of a vehicle luggage box. The header board is provided with a reinforcing part including a bead part extending in the vertical direction of the vehicle. The reinforcing part has a pair of first portions provided at both vehicle-width-direction ends of the header board, and a second portion provided between the pair of first portions in at least a vehicle-width-direction central section of the header board. The bead part provided on the second portion bulges toward at least one vehicle-longitudinal-direction side to a greater extent than the bead part provided on the first portions.
