DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a door mirror structure according to the present invention will be described with reference to FIGS.

In the drawings, the arrow FR indicates the forward direction of the vehicle body, the arrow IN indicates the inward direction of the vehicle width, and the arrow UP indicates the upward direction of the vehicle body.

As shown in FIG. 4, the door mirror 12 provided on the front side 10 of the vehicle is composed of a mirror body 14 and a base plate 16. The base plate 16 has a triangular shape in a side view, and is attached to a triangular corner portion 22 formed by the door window frame 18 and the door panel 20. Further, from the lower portion of the base plate 16, a stay 16A projects horizontally with respect to the vehicle body.

As shown in FIG. 3, the stay 16A protrudes obliquely rearward from the base plate 16 with respect to the vehicle body, and has an arc-shaped tip. A shaft 24 is provided upright at the center of the tip of the stay 16A. This shaft 24 has a mirror body 14
A socket 26 provided in a frame (not shown) is inserted, and the mirror body 14 is rotatable in the front-rear direction (the direction of the arrow A in FIG. 3 and the direction of the arrow B in FIG. 3) with respect to the vehicle body. As shown by the imaginary line, it can be folded forward and backward. The locus of the mirror surface 28 disposed in the opening of the mirror body 14 at this time is an arc centered on the shaft 24 as shown by the imaginary line N1 in FIG.

The door mirror 12 of the present embodiment is similar to that of FIG.
2, the mirror surface 28 of the mirror body 14 is located above the extension surface P of the upper surface 16B of the stay 16A, and as shown in FIG. 2, the upper and lower surfaces of the contact surface 16D of the base plate 16 attached to the vehicle body. A horizontal plane S passing through the directional center point Q is located between the upper end 14A and the lower end 14B of the mirror body 14. That is, the door mirror 12 of the present embodiment is not the door mirror 82 attached on the belt line 80A of the door outer panel 80 as shown in FIG. The mirror surface 28 is indicated by an imaginary line K1 in FIG.
It can swing in the longitudinal direction of the vehicle within the mirror angle adjustment range.

As shown in FIG. 1, an upper surface 16B of the stay 16A is inclined downward and toward the rear side of the vehicle body in a side view, and a shaft 24 which stands vertically with respect to the upper surface 16B.
Is inclined at a predetermined angle θ1 from the vertical line H toward the rear of the vehicle body. The trajectory of the mirror surface 28 is along the upper surface 16B as shown by an imaginary line N2 in FIG. 1, and the mirror surface 28 is a mirror surface shown by an imaginary line K2 in FIG. The vehicle can swing up and down within the angle adjustment range.

As shown in FIG. 2, the upper surface 16B of the stay 16A is inclined outward and downward in the vehicle width direction when viewed from the front, and the shaft 2 is vertically erected on the upper surface 16B.
4 is inclined at a predetermined angle θ2 outward from the vertical line H in the vehicle width direction.

As shown in FIG. 1 and FIG.
The thickness of the edge 16C of A is substantially the same as the thickness of the mirror visor 30 forming the outer shell of the mirror body 14.

Next, the operation of the present embodiment will be described. In the door mirror structure of the present embodiment, as shown in FIG. 1, even if the stay 16A is made thinner on the rear side of the vehicle body in order to avoid interference between the mirror surface 28 of the mirror body 14 and the stay 16A, the shaft 24 is moved from the vertical line H. A predetermined angle θ at the rear of the vehicle
The stay 16A on the front side of the vehicle body
The thickness of the stay stay 16 can be secured.
The area of the mirror surface 28 of the mirror body 14 can be increased without increasing the front projection area of the mirror body 14 while securing the intensity of A.

In the door mirror structure of the present embodiment, as shown in FIG. 2, the shaft 24 is inclined from the vertical line H to the outside in the vehicle width direction by a predetermined angle θ2 so that the thickness of the stay 16A inside the vehicle width direction is reduced. In addition to increasing the strength, the inclination angle θ1 and the inclination angle θ2 can be increased.
6 is set within a predetermined range, as shown in FIG. 6, it is possible to prevent the mirror body 14 from hanging down L1 when the mirror body 14 is tilted backward to the rear of the vehicle body by tilting the shaft 24 rearward at a predetermined angle. As shown in FIG. 5, the mirror body 14 can be tilted rearward substantially horizontally in a side view.

In this embodiment, as shown in FIG. 10, the mirror 24 has a mirror 24 in which the inclination angle θ1 of the shaft 24 toward the rear of the vehicle body and the inclination angle θ2 of the shaft 24 outward in the vehicle width direction are arbitrarily set. The lower limit of the hanging down of the body 14 when the body 14 can fall to the rear of the vehicle body is a straight line L1. Since the straight line M is formed, the inclination angle θ1 of the shaft 24 toward the rear of the vehicle body and the inclination angle θ2 of the shaft 24 toward the outside in the vehicle width direction are set to values within a range S indicated by oblique lines in FIG.

Also, as shown in FIG.
Is inclined only a predetermined angle outward from the vertical in the vehicle width direction, the thickness of the stay 16A inside the vehicle width direction is increased, and the strength of the stay 16A is ensured while the mirror body 1 is secured.
4 without increasing the front projection area.
Can be increased, but in this case, the mirror body 14 jumps up L2 when the mirror body 14 is tilted rearward of the vehicle body.
