There is. There is also a concern that water and mud splashed up from the rear tires T leak from the inside (left side) in the vehicle width direction of the parting portion 11D to the outside (right side), deteriorating the appearance quality.

Therefore, as shown in FIGS. 2 and 3, the vehicle mudguard 10 according to the present embodiment includes a reinforcing member 12 that can reinforce the partition 11D from the inside (left side) without spoiling the appearance. It is said that Further, the vehicle mudguard 10 is configured to include a double-sided tape 13 that can be easily joined to the parting portion 11D of the reinforcing member 12.

The reinforcing member 12 consists of an injection molded part of polypropylene (PP). The reinforcing member 12 is formed in a substantially U-shaped plate shape extending in the height direction along the inner surface (left side surface) of the parting portion 11D in a U-shaped cross section. Specifically, the reinforcing member 12 includes a first reinforcing surface portion 12A in the shape of a vertical panel extending in the height direction and the front-rear direction so as to face the inner surface of the parting portion 11D from the inside (left side) in the vehicle width direction. have The first reinforcing surface portion 12A has substantially the same height and front-to-back dimensions as the inner surface of the partition portion 11D, and is set in a state in which the first reinforcing surface portion 12A broadly contacts the inner surface from the inside over substantially the entire area of the inner surface of the partition portion 11D. It is considered to be a composition.

The reinforcing member 12 also has a second reinforcing surface portion 12B in the shape of a vertical panel that extends from the front edge of the first reinforcing surface portion 12A to the inside (left side) in the vehicle width direction along the first reinforcing surface portion 12A. . The reinforcing member 12 also has a third reinforcing surface portion 12C in the shape of a vertical panel that extends from the rear edge of the first reinforcing surface portion 12A to the inside (left side) in the vehicle width direction along the first reinforcing surface portion 12A. . The second reinforcing surface portion 12B and the third reinforcing surface portion 12C face each other in the front-rear direction.

The reinforcing member 12 is formed into a bent plate shape with a U-shape in cross section, which integrally includes the first reinforcing surface portion 12A, the second reinforcing surface portion 12B, and the third reinforcing surface portion 12C, so that it is resistant to bending and twisting. The structure has appropriately increased structural strength. In the reinforcing member 12, the outer surface (right side) of the first reinforcing surface portion 12A is attached to the inner surface (left side) of the parting portion 11D by double-sided tape 13 over most of the area in the height direction. They are joined together so that their surfaces are in contact with each other.

Further, the reinforcing member 12 has fitting claws 12D formed at two upper and lower positions on the rear surface of the third reinforcing surface portion 12C, which are inserted into the fitting holes 2A formed at corresponding locations on the rear bumper 2. The rear bumper 2 is also integrally connected to the front part of the rear bumper 2 by being inserted from the front and snap-fitted. By each of the above-mentioned connections, the reinforcing member 12 is appropriately fixed to both the parting portion 11D of the mudguard main body 11 and the front portion of the rear bumper 2.

Specifically, the reinforcing member 12 is set such that its first reinforcing surface portion 12A is in surface contact with the parting portion 11D from the inside over the entire height direction. Further, the reinforcing member 12 is set such that the second reinforcing surface portion 12B is in surface contact with the upright plate portion of the seat portion 11B of the mudguard main body 11 over the entire height direction from the rear side. Further, the reinforcing member 12 is set such that its third reinforcing surface portion 12C is in surface contact with the front portion of the rear bumper 2 over the entire height direction from the front side.

By attaching the reinforcing member 12, the parting portion 11D is appropriately reinforced from the inside over a wide range in the height direction. Therefore, the parting portion 11D is configured to be difficult to fluctuate greatly in the vehicle width direction even when subjected to an external load such as vehicle vibration. Specifically, the parting portion 11D is appropriately reinforced from the inside by a reinforcing member 12 having a high structural strength and having a bent plate shape with a U-shaped cross section. Further, the parting portion 11D is more appropriately reinforced from the inside by the structure in which the reinforcing member 12 is also fixed to the front portion of the rear bumper 2.

In addition, since the reinforcing member 12 has a substantially U-shaped plate shape, the reinforcing member 12 prevents water or mud from splashing up from the rear tire T from entering the parting portion 11D from the inside (left side) in the width direction of the vehicle. The structure is such that leakage to the right side is prevented. Therefore, it is possible to appropriately prevent deterioration in the appearance quality of the parting portion 11D. In this way, by configuring the reinforcing member 12, which is constructed separately from the mudguard main body 11, to be joined to the parting part 11D, the parting part 11D can be formed easily and appropriately without making the parting part 11D itself a complicated shape. can be reinforced.
