Abstract

PROBLEM TO BE SOLVED: To provide a mud guard for a vehicle which facilitates assembly of the spacer to the mud guard body while decreasing the cost by integrally forming the spacer with the edge of the mud guard body. SOLUTION: In a synthetic resin mud guard for a vehicle integrally formed using a slide die, which has an attachment surface on a substantially flat surface in the slide die slide direction contacting the slide die, and in which a spacer is interposed in this attachment surface and which is fastened with a bolt to the vehicle body, a spacer 2 is integrally formed in a position distanced from a mud guard body 1 via a string-like thin wall portion 17. Also, a fitting portion which fits in an attachment hole 15 formed in the mud guard body 1 is formed protruding from the spacer 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mudguard for an automobile mounted on an automobile body at a rear side of the tire to prevent mud splashing from the tire.

[0002]

2. Description of the Related Art As an automobile mudguard, an integrally molded product made of a synthetic resin is generally used, and a slide type is usually used for molding because of its complicated shape. For example, FIG.
As shown in FIG. 4, a wheel house b of an automobile body a
A vertical wall portion 10 attached to a lower rear portion of the vehicle so as to be continuous with the wheel house b and hanging downward, and extends obliquely rearward and upward from a lower end of the vertical wall portion 10 so that an extending end 201 is attached to the vehicle body a. A bottom wall portion 20 to be fixed, and a side wall portion 30 connecting the vertical wall portion 10 and the bottom wall portion 20 outside the vehicle.
In the synthetic resin mat guard B having:
0, a negative corner 40 surrounded by the bottom wall 20 and the side wall 30
Therefore, a slide mold is used for molding this portion. In this case, the sliding direction of the slide type is the vertical wall portion 10.
And approximately parallel.

The mudguard B has a vertical wall 1
When fixing 0 to the vehicle body a, if a boss is required on the mounting surface of the vertical wall portion 10 due to constraints on the side of the vehicle body a, the boss forms a negative angle with the slide-type portion. The boss cannot be formed integrally. Therefore, in such a case, conventionally, another spacer 50 is set. This spacer 50 is used for the vertical wall 10.
Is attached by heat or adhesive.

[0004]

The above-mentioned conventional mud guard requires a separate spacer, which is costly. In addition, the spacer is detached from the mud guard main body to be out of stock, or the position of the mounting hole between the spacer and the mud guard main body is reduced. Matching was troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a structure in which a spacer is integrally formed on an edge of a mudguard main body, thereby reducing costs and facilitating assembly work of the spacer to the mudguard main body. The purpose is to provide mudguards.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, there is provided an apparatus which is integrally formed using a slide die and is mounted on a surface substantially parallel to a slide direction of the slide die in contact with the slide die. A mudguard made of a synthetic resin which is fixed to the body of the vehicle by bolts with a spacer interposed between the mounting surface and the spacer 2 through a thin string-like portion 17 at the end edge of the mudguard body 1. Is integrally molded at a position away from the mudguard body 1,
When the mudguard is attached, the string-shaped thin portion 17 is bent so that the spacer 2 is combined with the mudguard main body 1 and fixed to the automobile body a together with the mudguard main body 1.

According to a second aspect of the present invention, in the mudguard for a vehicle according to the first aspect, a fitting portion 22 that fits into a mounting hole 15 formed in the mudguard body 1 is protruded from the spacer 2. It is characterized by.

[0008]

FIG. 1 is a perspective view of a mudguard for an automobile according to the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG. As shown in FIGS. 1 and 2, mudguard A is
This is a synthetic resin integrally molded product having a mudguard main body 1 and a spacer 2 integrally formed on an edge of the mudguard main body 1. The mudguard main body 1 is attached to a lower rear portion of a wheel house b of an automobile body a so as to be continuous with the wheel house b and has a vertical wall portion 11 which hangs downward, similarly to the conventional mud guard shown in FIGS. The bottom wall portion 12 extends obliquely rearward and upward from the lower end of the vertical wall portion 11 and has an extending end fixed to the vehicle body a, and the vertical wall portion 11 and the bottom wall portion 12 are connected outside the vehicle. Side wall 13
And a negative angle portion 14 surrounded by the vertical wall portion 11, the bottom wall portion 12, and the side wall portion 13, and a slide die is used for molding this portion.

At the upper end of the vertical wall portion 11 of the mudguard body 1, a plurality of bolt insertion holes 15 and 16 for attaching the mudguard A to the vehicle body a are formed.
The spacer 2 is integrally formed on the edge on the inside of the vehicle via a thin string portion 17. The string-like thin portion 17 is shown in FIG.
As shown by the dotted line, the spacer 2 can be integrally formed at a position away from the mudguard main body 1 where the slide die is not located. The spacer 2 has a main body portion 21 formed in a frusto-conical shape, and a columnar projection 22 which is fitted to the bolt insertion hole 15 located inside the vehicle among the bolt insertion holes 15 and 16 protrudes from the bottom surface. In addition, a through hole 23 penetrating the main body 21 and the columnar projection 22 is provided. The spacer 2 is oriented in a normal direction when the string-shaped thin portion 17 is bent and turned 180 ° rearward. In the figure, 19 is the mudguard body 1
This is a bolt insertion hole formed in the bottom wall portion 13 of FIG.

In order to attach the mudguard A to the automobile body a, first, the string-like thin portion 17 is bent, and the columnar projection 22 of the spacer 2 is fitted into the bolt insertion hole 15 of the mudguard body 1. Thereby, the spacer 2
Are combined with the mudguard body 1, and thereafter, the bolts c, d, and e are inserted into the bolt insertion holes 15, 16, and 19 formed in the mudguard body 1 to fix the mudguard A to the vehicle body a. I do. Note that the columnar projection 22 of the spacer 2 is fitted in the bolt insertion hole 15, but the spacer 2 is
2, and the bolt c inserted into the bolt insertion hole 15 is actually inserted into the through hole 23 of the spacer 2.

[0011]

As described above, according to the automobile mudguard of the present invention, the mounting surface is formed integrally with the sliding die, and has a mounting surface on a surface substantially parallel to the sliding direction of the sliding die in contact with the sliding die. In a synthetic resin mudguard that is bolted and fixed to the body of an automobile with a spacer interposed on the mounting surface, the spacer is integrally formed at a position away from the mudguard main body via a string-shaped thin portion at an end edge of the mudguard main body. This eliminates the need for a separate spacer and can reduce the cost. In addition, by projecting a fitting portion that fits into a mounting hole formed in the mudguard main body on the spacer, there is an effect that the operation of assembling the spacer to the mudguard main body can be easily performed.
