The spare tire carrier 2'is fixed at a predetermined height position of the back door 1 ', and the carrier portion 3'has a plurality of support bolts 4 corresponding to the hub holes penetrating the wheel of the spare tire T. ′ Is projected horizontally. The upper and lower ends of the rudder 17 'are fastened to the back door 1'by fastening hardware (not shown).

[0003]

[Problems to be solved by the device]

 By the way, when the spare tire T is mounted on the spare tire carrier 2'in the above-mentioned conventional tire, the spare tire T is lifted up to a height position facing the carrier portion 3'of the spare tire carrier 2 ', and this lifting is performed. While maintaining the state, the hub holes of the spare tire T must be aligned and fitted into the support bolts 4'of the carrier portion 3 ', which is difficult and requires a lot of labor.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a spare tire carrier capable of easily attaching and detaching a spare tire to and from a spare tire carrier by effectively utilizing a ladder mounted on a back door. Is to provide an auxiliary device of

[0005]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides a vehicle in which a spare tire carrier and a rudder are mounted on a back door, and the rudder is detachably mounted on the back door at both upper and lower ends of the rudder. Further, a mounting member is provided, and the ladder is configured to be bendable by the first ladder portion and the second ladder portion, while on the upper surface of the rear bumper of the vehicle, below the spare tire carrier. A holding member is provided for holding the first ladder portion in a detachable manner along the upper surface of the rear bumper, and further, when the first ladder portion is held along the upper surface of the rear bumper, the holding member is provided. The rudder heights of the first and second rudder portions are set so that the two rudder portions are inclined downward and the downwardly inclined ends are in contact with the road surface.

[0006]

[Action]

 In the auxiliary device for the spare tire carrier configured as described above, when the rudder is attached to the back door of the vehicle, the rudder functions as a ladder. When mounting a spare tire on a spare tire carrier, after removing the rudder from the back door of the vehicle, hold the first rudder part along the rear bumper by the holding member and make the second rudder part inclined downward. The lower end of the lever is brought into contact with the road surface.

Here, the spare tire on the road surface is rolled vertically and is moved to the first ladder portion on the rear bumper through the second ladder portion having the above-described downward slope, so that the spare tire can be substantially replaced with the spare tire carrier. It can be easily moved to the opposite height position. Then, while slightly lifting the spare tire carrier, fitting the hub hole into the support bolt of the spare tire carrier, and then tightening the nut, the spare tire carrier is fitted with the spare tire.

When removing the spare tire from the spare tire carrier, the spare tire is removed by operating in the reverse order of the above.
