Description

  The present invention relates to a mounting structure of a spare tire cover formed so as to cover a spare tire mounted on a vehicle.

  Conventionally, for example, as disclosed in Patent Documents 1 and 2, when a spare tire is mounted on a back door of a vehicle, the spare tire is covered with a spare tire cover. A shaft that projects in the direction of the center line of the spare tire is provided at the center of the spare tire cover of Patent Document 1, while a hollow rod that projects in the direction of the center line of the spare tire is provided on the vehicle side. . When attaching the spare tire cover, insert the shaft of the spare tire cover into the hollow rod on the vehicle side and push the spare tire cover toward the vehicle side so that the peripheral wall of the spare tire cover covers the tread surface of the spare tire Position.

Moreover, in the spare tire cover of Patent Document 2, a pressing member in contact with the tread surface is provided on the inner surface of the peripheral wall portion covering the tread surface of the spare tire, and a slit is formed in the peripheral wall portion. When the spare tire cover is attached, the inner wall of the peripheral wall portion is reduced by narrowing the width of the slit of the peripheral wall portion with a metal fitting so that the pressing member is pressed against the tread surface of the spare tire.

  By the way, the size of the tire mounted on the vehicle may be different depending on the grade or the like even in the same vehicle type. In this case, the size of the spare tire is also different. On the other hand, it is only necessary to prepare a dedicated spare tire cover for each size of the spare tire, but if so, the cost of the spare tire cover increases.

  Therefore, it is conceivable to share a spare tire cover between spare tires of different sizes. However, in the spare tire cover of Patent Document 1, the peripheral wall portion is formed so as to cover the tread surface. Therefore, if the spare tire has a small outer diameter, the peripheral wall portion floats from the tread surface of the spare tire. There is a risk that the mounting strength of the spare tire cover will be insufficient. In the spare tire cover of Patent Document 2, the inner diameter of the peripheral wall portion is reduced so that the holding member is pressed against the tread surface of the spare tire. It may be difficult to firmly press the stop member against the tread surface of the spare tire, which may cause insufficient mounting strength. In order to avoid this, it is only necessary to increase the number of fixing points of the spare tire cover. However, if the number of fixing points increases, the workability of attaching the spare tire cover may be deteriorated.

  The present invention has been made in view of such points, and an object of the present invention is to allow a spare tire cover to be securely attached regardless of the size of the spare tire when the spare tire cover is attached to a vehicle. In order to improve the mounting workability.

  In order to achieve the above object, in the first invention, a spare tire configured to attach a spare tire cover that covers a spare tire mounted on a vehicle along the center line of the spare tire to the vehicle.

And a positioning portion for positioning the fixing portion, and the fixing portion is positioned on the positioning portion before the engaging portion engages with the engaged portion in a state where the slide portion has advanced. Is A configuration which is arranged to.

  According to a second invention, in the first invention, the slide portion of the spare tire cover is formed in a cylindrical shape into which the protrusion is inserted, and the slide portion guides the slide portion in the protrusion direction of the protrusion. It is set as the structure by which the guide part to be provided is provided.

  According to the first aspect of the invention, when the spare tire cover is attached, when the slide portion is in the advanced state and the spare tire cover is moved along the center line of the spare tire, the engaging portion becomes the engaged portion. Before the engagement, the fixed part of the slide part can be positioned by the positioning part of the vehicle. When the spare tire cover is further moved in the mounting direction, the projecting portion moves with respect to the positioned slide portion, so that the posture of the spare tire cover during movement can be stabilized. As a result, the engaging portion of the spare tire cover can be easily aligned and engaged with the engaged portion of the vehicle, and the mounting workability can be improved. In addition, the center side of the spare tire cover is fixed to the vehicle by the fixing portion of the slide portion, and the engaging portion of the peripheral wall portion of the spare tire cover is engaged with the engaged portion of the vehicle. Regardless, the mounting strength of the spare tire cover can be sufficiently secured.

  According to the second invention, when the spare tire cover is attached, the slide portion is guided by the guide portion, so that the posture of the spare tire cover during movement can be further stabilized.
