Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a protector for a tire house that covers the inside of a tire house of a vehicle such as an automobile.

(Prior Art) A tire house 1 of an automobile includes a metal outer panel 3 and an inner panel 4 that cover a tread surface 2a and an inner side surface 2b of a tire 2 so as to face each other, as shown in FIG. 5, for example.
The protector 5 made of synthetic resin is attached to cover the insides of the panels 3 and 4, and the protector 5 reduces the sound of pebbles and muddy water scattered by the rotation of the tire 2 and muddy water. Prevents the metal from directly attaching to the panels 3 and 4 and causing corrosion. The tire house 1 is provided with a strut 7 integrally formed of a spring, a shock absorber or the like that supports an axle 6 to which the tire 2 is attached.

Conventionally, the protector 5 faces the tread surface 2a of the tire 2 as shown in FIG. 6 and FIG.
A semi-circular fender protector 8 covering the tire 4 and the tire 2
And a semi-disc-shaped splash protector 9 covering the panel 4 facing the inner side 2b of the tire house 1.
When the protectors 8 and 9 are attached to the parts, some of them are connected to each other. The reason that the protector 5 is divided into two parts is that the protector 5 is attached after the slat 7 is attached to the tire house 1, and it is necessary to separate the protectors 8 and 9 on the outer side and the inner side of the strut 7. .

(Problems to be Solved by the Invention) As described above, in the conventional protector for the tire house, the fender protector 8 and the splash protector 9 are separately configured, and therefore, in the mounted state as shown in FIG. There is a gap between the protectors 8 and 9 and the panel 4 is exposed, and muddy water or pebbles scattered by the rotation of the tire directly hits the exposed panel 4 to make an abnormal noise or adhere to muddy water. Easily causes corrosion.

In addition, since both parts are thin and large parts, deformation and dimensional variation after molding are large, not only a great number of man-hours are required for dimensional control of the connection part, but also in a part where the metal panel is not exposed. However, a gap is likely to be formed at the joint between the protectors 8 and 9, and muddy water or the like enters from there.

Further, when molding the protectors 8 and 9, both parts require a large molding die, which results in high die cost.

Further, for example, as shown in FIG. 8, the fender protector 8 is formed by sheet press molding, but by cutting off the fender protector 8, a lot of dust material including the side wall portion 10 and the like remains, resulting in a high material cost. .

The present invention has been made in view of the problems as described above, and reduces the exposed portion inside the panel of the tire house to reduce the generation of abnormal noise due to the collision of pebbles and the like, and to prevent the corrosion caused by the adhesion of muddy water. An object of the present invention is to provide a protector for a vehicle tire house that can reduce the die cost and material cost.
