[Problem that the invention attempts to solve]

However, in the conventional vehicle door mirror device described above, the deep groove 15 for inserting the mounting portion 72 of the cover 7 is provided on the outside of the concave hemispherical surface 13 of the protrusion 11 of the body 1. 11 becomes larger, and the attachment part 7 of the cover 7 at the bottom of the body 1 becomes larger.
The part to which body 2 is attached becomes larger, and the weight of body 1, etc. increases. Further, since the deep groove 15 is provided in the body 1 and the flange portion 44 is provided in the first spherical washer 4, the body 1
Another problem is that the structure of the first spherical washer 4 is complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a door mirror device for a vehicle in which the portion of the body on which the cover is attached is downsized and the structure of the body and the spherical washer is simplified.

[Means for solving problems]

The present invention is characterized in that the body and the spherical washer are provided with opposing holding portions for holding the other end of the cover.

[Effect]

In the present invention, the body and the spherical washer are provided with opposing holding parts for holding the other end of the cover, so that the other end of the cover can be held between the holding part of the cover and the holding part of the spherical washer. A space is formed.

〔Example〕

Hereinafter, two examples of the embodiments of the vehicle door mirror device according to the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a partial sectional view showing a first embodiment of a vehicle door mirror device according to the present invention. In the figure, the same reference numerals as in FIGS. 4 to 6 indicate the same parts. In this embodiment, the vehicular door mirror device of the present invention is arranged such that the clamping part 1 is connected to the outside of the concave hemispherical surface 13 of the body 1 through the flat bottom part 14 or the hollow part 16.
7 will be provided. On the other hand, a clamping part 45 is provided on the hemispherical part 40 of the first spherical washer 4 so as to face the clamping part 17 of the body 1. The clamping portion 17 of this body 1 and the first
The mounting part 72 of the cover 7 is held between the holding part 45 of the spherical washer 4.

As described above, the vehicle door mirror device of the present invention according to this embodiment includes the body 1 and the first spherical washer 4.
In addition, since the clamping parts 17 and 45 that clamp the mounting part 72 at the other end of the cover 7 are provided facing each other, the cover can be mounted between the clamping part 17 of the body 1 and the clamping part 45 of the first spherical washer 4. A space is formed for holding the mounting portion 72 at the other end of the mounting portion 7 . Therefore, the diameter of the protrusion 11 of the body 1 can be smaller than that of a conventional vehicle door mirror device in which the protrusion 11 of the body 1 is provided with a deep groove 15 for inserting the attachment part 72 of the cover 7. . Further, it is not necessary to provide the deep groove 15 in the body 1 and the flange portion 44 in the first spherical washer 4.

FIG. 2 is a partial sectional view showing a second embodiment of the vehicle door mirror device according to the present invention, and FIG. 3 is a sectional view taken along the line -- in FIG. In the figure, the first
The same reference numerals as in the figure and FIGS. 4 to 6 indicate the same parts. In the vehicle door mirror device of the present invention in this embodiment, a nut receiver 18 is provided on the body 1, a nut 61 screwed into the body 6 is fitted into the nut receiver 18, and the upper surface of the protrusion 11 of the body 1 is connected to the nut 61. Washers 64, 65 are installed between the lower surface of the receiver 18.
A compression spring 63 is interposed therebetween. In addition,
In the figure, 66 is a spring washer, and 67 is a washer. This embodiment can achieve the same effects as those of the previous embodiment.

[Effect of idea]

As is clear from the above, in the vehicle door mirror device of the present invention, the body and the spherical washer are provided with the clamping part for clamping the other end of the cover, so that the clamping part of the body and the clamping part of the spherical washer are arranged opposite to each other. A space for holding the other end of the cover is formed between them. Therefore, compared to a conventional vehicle door mirror device in which a deep groove for inserting the other end of the cover is provided in the protrusion of the body, the diameter of the protrusion of the body can be smaller. As a result, the portion of the lower part of the body to which the other end of the cover is attached can be made smaller. Further, since it is not necessary to provide a deep groove in the body and a flange in the spherical washer, the structures of the body and the spherical washer can be simplified.
