Abstract: An object of the present invention is to provide a convenient on-board tool storage structure, the storage structure allowing a storage location of an on-board tool to be seen easily, and allowing the on-board tool to be taken out without detaching a spare tire. The on-board tool storage structure of the present invention is formed in a supporting member 110 having a mounting surface 112 on which a spare tire 106 is mounted with such an inclination that a vehicle rear side thereof is elevated. A storage groove 114 which stores the tool therein is formed in the supporting member. A vehicle rear side end portion of the storage groove is exposed at a vehicle rear side of the spare tire. A distance along the storage groove between a position in which the storage groove starts to be exposed and a back panel 104 is shorter than the total length of the tool. A deep groove portion 114a is formed at a lower portion of the storage groove in such a manner as to be deeper toward the rear of the vehicle.
