PROBLEM TO BE SOLVED: To secure an impact energy absorbing stroke of a vehicle at the time of a vehicular rear collision, and to improve a take-out property of a spare tire from a spare tire storage portion. SOLUTION: When the spare tire 22 is taken out of the spare tire storage portion 16, if a spare tire board 24 moves to a vehicular rear side, the spare tire board 24 is guided to the upper side of the vehicular rear side along a rail portion 20A of a guide rail 20. At the time of the vehicular rear collision, the spare tire board 24 relatively moves to the vehicular rear side to the guide rail 20 moving to a vehicular front side, so that the spare tire board 24 is guided to the upper side of the vehicular rear side along the rail portion 20A of the guide rail 20, and a floor panel 14 can contribute to collision energy absorption.
