[0005]

By the way, when the trim board is simply provided so as to cover the inner side wall of the vehicle compartment as in the above-mentioned conventional technique, the spare tire supported by the inner side wall main body is arranged. The position will be closer to the center side in the width direction of the vehicle compartment to avoid interference with the trim board,
This is not preferable because it narrows the passenger space and the cargo space in the width direction of the passenger compartment.

On the other hand, the trim board is supported by the vehicle body such as the inner side wall, but since the trim board has a large area and low strength and rigidity, there is a possibility that the trim board may shake due to vibration of the vehicle body while the vehicle is running. There is.

Further, as described above, the spare tire is firmly supported by the inner wall main body by the supporting means, but since the spare tire is heavy, the spare tire also rattles due to the vibration of the vehicle body. There is a risk.

Therefore, in order to prevent rattling of the spare tire, as described in the prior art publication,
When the spare tire is supported by the supporting means, it is conceivable that a part of the tire of the spare tire is pressed against the inner wall. However, even if a part of the tire is pressed in this way, and this state is for a long time, the part that was pressed and the other part may have different hues due to the discoloration of the tire surface over time. As a result, the appearance of the spare tire may deteriorate.

The present invention has been made by paying attention to the above circumstances. In the case where a spare tire is supported on the inner side wall of the vehicle compartment from the vehicle interior side, the inner wall is provided from the vehicle interior side. Even when a trim board for covering is provided, it is an object to prevent the passenger space and the cargo space in the width direction of the vehicle compartment from being significantly narrowed by the spare tire.

Further, the trim board and the spare tire are prevented from rattling due to the vibration of the vehicle body while the automobile is running, and further, as described above, the support of the spare tire on the inner wall is assumed to be for a long time. The challenge is also to keep the appearance of this spare tire in good condition.

They face each other with a slight gap.

Since the rim 29 has a high strength and rigidity because it needs to support the tire 27, the spare tire 22 has the elastic body 41 and the wheel house inner according to the above structure. The spare tire 22 is more firmly supported by the panel 16 and more reliably prevented from rattling.

The above wheel house inner panel 1
Since a part of the rim 29 pressed against the 6 side has a smaller area than a part of the tire 27 when a part of the tire 27 is pressed, a part of the rim 29 is fitted. The area of the through hole 38 can be small.

Therefore, as described above, since the area of the through hole 38 is small, the bulging portion 36 of the trim board 34 is required.
Of the trim board 34 is prevented and the appearance of the trim board 34 is kept good.

Moreover, the rim 29 of the spare tire 22 is
Since the tire is pressed against the wheel house inner panel 16 side, the tire 27 is pressed against the bulging portion 36 in terms of pressure and area.

Therefore, even if a part of the tire 27 of the spare tire 22 is pressed against the bulging portion 36 of the trim board 34 for a long time due to the long-term support of the spare tire 22, the surface of the tire 27 is The discoloration of the spare tire 22 becomes more uniform throughout, and therefore, the appearance when the spare tire 22 is used is kept good.

[0041]

The effects of the present invention are as follows.

According to the first aspect of the present invention, the inner side wall of the vehicle body forming the side surface of the passenger compartment constitutes an upper part of the inner side wall main body extending substantially vertically, and the lower part of the inner side wall constitutes a lower part of the vehicle. A wheel house inner panel bulging toward the inner side of the compartment, and a supporting means for detachably supporting the spare tire from the compartment side to the inner wall main body portion is provided, and the wheel house in a side view of the vehicle body. In a vehicle provided with a trim board that arranges this spare tire so that the inner panel and the lower portion of the spare tire overlap each other, and provides a trim board that covers the inner side wall from the cabin side,

A through hole penetrating in the width direction of the vehicle body is formed in the portion of the trim board facing the wheel house inner panel, and a part of the lower portion of the spare tire is fitted into the through hole. The effect occurs.

That is, when the trim board is provided so as to cover the inner wall of the vehicle compartment as described above, the spare tires supported by the inner wall main body are arranged at positions where interference with the trim board is avoided. Although it tends to be closer to the center side in the width direction of the vehicle compartment, as described above, since a part of the spare tire is fitted into the through hole formed in the trim board, the wheels are closer to the center side of the vehicle compartment. Is prevented.

Therefore, as described above, the spare tire is supported on the inner wall of the passenger compartment from the passenger compartment side, and
Even when a trim board is provided to cover the inner wall from the passenger compartment side, it is possible that the spare tire significantly narrows the passenger space and the cargo space in the passenger compartment adjacent to the wheel house inner panel in the width direction of the passenger compartment. To be prevented.

According to a second aspect of the present invention, the trim board portion is joined to the wheel house inner panel via an elastic body, and a part of the lower portion of the spare tire is pressed against the elastic body.

Here, the trim board is a plate material having a large area and has a low rigidity and thus is easily bent. However, as described above, the trim board portion is interposed by the elastic body. Since it is joined to the wheel house inner panel having high strength and rigidity, the trim board is prevented from rattling due to the vibration of the vehicle body while the vehicle is running.

Further, as described above, the spare tire is supported by the inner wall main body portion by the supporting means, but since the spare tire is heavy, there is a possibility that the spare tire also rattles due to the vibration of the vehicle body. However, since a part of the spare tire is pressed against the elastic body directly through the through hole as described above, vibration is damped by the elastic body and the free end side of the spare tire has the elastic body. The spare wheel is securely supported by the wheel house inner panel via the so that the spare tire is more reliably prevented from rattling.

According to the third aspect of the invention, a part of the lower portion of the spare tire is a part of the rim which constitutes the spare tire.

Here, since the rim has high strength and rigidity because it needs to support the tire, according to the above construction, the spare tire can be further attached to the wheel house inner panel through the elastic body. It is firmly supported and more reliably prevents the spare tire from rattling.

Further, since a part of the rim pressed against the wheel house inner panel side has a smaller area than a part of this tire when a part of the tire of the spare tire is pressed against, The area of the through hole into which a part of the rim is fitted can be small.

Therefore, since the area of the through-hole is small as described above, the strength of the bulging portion of the trim board is prevented from being lowered, and the appearance of the trim board is kept good.

Moreover, since the rim of the spare tire is pressed against the wheel house inner panel side, the pressure contact of the tire with the trim board portion can be suppressed in terms of pressure and area.

Therefore, even if a part of the tire of the spare tire is pressed against the trim board part for a long time due to the long-term support of the spare tire, the discoloration of the surface of the tire with time is totally caused. Therefore, the appearance when the spare tire is used is kept good.
