Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a fixing structure for a pipe-type washer nozzle that is used, for example, to spray washing fluid onto the glass surface of an automobile.

(Prior Art) Conventionally, as a fixing structure for a pipe-type washer nozzle as described above, there have been structures shown in FIGS. 3 and 4, for example.

That is, the metal bracket 101 is connected to the pipe portion 103 that constitutes the washer nozzle 102.
As shown in Fig. 3, it has a mounting hole 104 for passing a fixing bolt, etc. on one end thereof.
Two roughly U-shaped upright portions 105, 105 are erected in a substantially parallel relationship. Further, the upright portions 105, 105 have a U-shaped groove 10 for pipe engagement.
5a is formed with a notch.

When fixing the pipe portion 103 to the bracket 101 as described above, both U-shaped grooves 105 are
a, 105a, and then, as shown in FIG.
Tighten the tips of 05 in the direction of approaching each other. This fixes the pipe portion 103 to the bracket 101.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional pipe-type washer nozzle fixing structure, the upright portions 105, 105 with respect to the pipe portion 103 having a uniform outer diameter
Because of the crimping, when force is applied from the longitudinal direction of the washer nozzle 102, the pipe portion 103 tends to move in the longitudinal direction, which may cause the fixed position of the pipe portion 103 to shift relative to the bracket 101. There was a problem.

Also, the washer nozzle 1 is attached to the bracket 101.
When fixing the washer nozzle 102, there is no identification means on the pipe portion 103 to indicate the fixing position, and when fixing the washer nozzle 102 to the vehicle body, the fixing position of the washer nozzle 102 is already determined. There was a problem that it took a lot of time to fix it.

Therefore, the present invention was devised by focusing on the above-mentioned conventional problems, and it is possible to firmly fix the pipe body of the washer nozzle in a predetermined position against the force applied from the longitudinal direction, and also to attach the washer nozzle to the bracket. It is an object of the present invention to provide a fixing structure for a pipe-type washer nozzle that allows easy and accurate positioning when fixing.

[Structure of the invention] (Means for solving the problems) The structure of the invention to achieve the above purpose is as follows:
In the fixing structure of the pipe type washer nozzle, in which the pipe body of the pipe type washer nozzle is fixed to a bracket and the bracket is fixed to the vehicle body side, a part of the pipe body has an outer diameter dimension smaller than the outer diameter dimension of the pipe body. A small diameter pipe portion is formed, and the bracket is integrally provided with a concave groove that contacts the pipe body and a rising piece that grips the pipe body at a position that coincides with the small diameter pipe portion, and the pipe body is brought into contact with the concave groove. Then, the small diameter pipe section is fixed by crimping the rising piece.

(Example) Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 and FIG. 2 are diagrams showing an embodiment of the present invention.

That is, the metal bracket 1 is used to fix the pipe body 3 constituting the washer nozzle 2 to the vehicle body, and as shown in FIG. 2, it has fixing holes for passing fixing bolts, etc. 4
A concave groove 5 having a shape matching the shape of the pipe portion 3 of the washer nozzle 2 is provided approximately at the center of the bracket 1, and at both ends thereof, the bracket 1 is partially cut and raised. The formed rising pieces 6, 6 are respectively erected at alternate positions. Further, a small diameter pipe portion 7 having an outer diameter smaller than the outer diameter of the pipe main body 3 is formed in a part of the pipe main body 3 of the wash nozzle 2.

Here, the length of the small diameter pipe portion 7 is the length of the rising piece 6 on the left side in FIG. 2 of the bracket 1.
It is slightly larger than the width dimension of .

Therefore, when fixing the pipe body 3 to the bracket 1, the pipe body 3 is fixed to the bracket 1.
As shown in FIG. 1, while bringing the small diameter pipe portion 7 of the pipe body 3 into contact with the raised piece 6 on the left side in FIG. After being crimped and deformed so as to wrap around the small diameter pipe part 6 in a state that it is aligned with the small diameter pipe part 7, the rising piece 6 on the right side in FIG.
is crimped and deformed around the pipe body 3. This fixes the pipe body 3 to the bracket 1.

In other words, the rising piece 6 on the left side in FIG.
By crimping and deforming the pipe body 3,
The bracket 1 and the pipe body 3 are positioned by a groove 5 shaped to match the pipe body 3.
Since the contact area with the pipe body 3 is increased, the pipe body 3 can be easily and easily fixed to the bracket 1, and even if force is applied from the longitudinal direction of the pipe body 3, the small diameter pipe part 7 can be easily fixed. Since the rising pieces 6 on the left side in FIG. 2 coincide with each other, the pipe body 3 does not move in the longitudinal direction. By crimping and deforming the rising piece 6 on the right side in FIG. 2, the pipe body 3 is more firmly fixed to the bracket 1.

[Effects of the invention] As explained above, according to the invention, because of the above-described structure, the positioning when fixing the pipe body to the bracket can be done easily and accurately, and the bracket can be fixed to the small diameter pipe part. Since the rising pieces are crimped and fixed in alignment, an excellent effect is obtained in that the pipe body does not easily shift due to force applied to the pipe body from the longitudinal direction.
