Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an exploded perspective view showing an embodiment of the rearview mirror holding mechanism of the present invention, which is applied to an anti-glare rearview mirror in which the reflection angle of the mirror is manually changed by operating a lever. The holding mechanism of the present invention includes a support 10 installed in a housing 1 that holds a mirror.
It is composed of a spherical pivot 7 integrally formed at the tip of a stay 6 fixed to the vehicle body, a bush 20 that holds the pivot 7, and a plate 15 abutted on the tip side of the pivot 7. A stay insertion hole 2 is provided in the center of the back surface of the housing 1, and a lever insertion hole 4 is provided in the center of the bottom wall 3 of the housing 1. Further, a recessed portion for installing the support 10 is formed in the ceiling portion of the inner wall.

The support 10 has a shaft portion formed at its upper end.
It is attached to a recess in the ceiling of the inner wall of the housing 1. A hole 11 through which the stay 6 and pivot 7 are inserted is provided in the center of the support 10. Screw holes 12, 12 for attaching the plate 15 are formed on both sides of this hole 11. Clip spring 2 is attached to the lower half of the front of support 10.
7 is installed, and a lever 26 for switching the reflection angle of the mirror is fitted to the lower end of the clip spring 27. The plate 15 is formed of a spring material, and has a protrusion 16 in the center with an inner surface that fits into the bush 20. A rectangular engagement hole 17 is formed in the center, and on both sides of the protrusion 16, a rectangular engagement hole 17 is formed. screw hole 1
8 and 18 have been established. A bush 20, which is interposed between the support 10 and the plate 15 and which encloses the pivot 7, has an inner diameter that comes into close contact with the pivot 7, and has several slits 21 formed therein, and has elasticity due to the slits 21. . A square locking portion 2 is provided on the tip side of the bush 20 to prevent rotation.
2 is highlighted.

Next, the assembly of this rearview mirror holding mechanism will be explained. First, the outer edge of the opening of the bush 20 is fitted into the hole wall 11a of the support 10, and the locking part 22 on the tip side of the bush 20 and the engagement hole 17 of the plate 15 are fitted, and the inner surface of the bush 20 and the convex part 16 are fitted. Install the plate 15 so that the screws 30 and 3 are engaged with each other, and
0 through the screw holes 18, 18 and screwed into the screw holes 12, 12 of the support 10 to fix the plate 15 to the support 10.

After sub-assembling as shown in FIG. 2 in this manner, the stay 6 is driven in the direction of arrow A by a press or the like. As shown in FIG. 3, the diameter D ₁ of the hole 11 opened in the support 10 is larger than the diameter d of the pivot 7 and smaller than the outer diameter D ₂ of the bush 20, so the force of driving the stay 6 with a press etc. At the same time as the pivot 7 passes through the hole 11 of the support 10, the opening and inner diameter of the hollow spherical bush 20 temporarily widen due to the presence of the slit 21. The opening of the bush 20 slides with the pivot 7 at the tip of the stay while expanding in diameter, and since it exceeds the maximum diameter part, the pivot 7 fits inside the bush 20, and then the diameter of the bush 20, which had temporarily increased, increases. The inner diameter and opening are returned to their original positions, and the outer surface of the pivot 7 and the inner surface of the bush 20 fit together (FIG. 3). Also, when the stay 6 is driven in, the plate 15 is lifted up and the reaction force causes the bush 2 to move.
0 against the hole wall 11a of the support 10,
The opening size of the bush 20 is reduced so that the pivot 7 cannot be removed from the bush 20.

As mentioned above, the retention mechanism can be easily assembled. Furthermore, the lever 26 is inserted into the lever insertion hole 4.
is inserted, the clip spring 27 is fitted to the lever 26, and this is installed in the lower front half of the support 10, thereby providing an anti-glare angle conversion mechanism.

The room mirror assembled in this way is
The reflection angle of the mirror is adjusted so that you can clearly see what's behind you while driving. When the housing 1 is held and rotated, the pivot 7 at the tip of the stay 6 fixed to the vehicle body and the support 10 attached to the housing 1
The bush 20 that fits into the hole wall 11a and holds the pivot 7 slides, and the reflection angle of the mirror changes, making it possible to adjust the reflection angle. At this time, the plate 15 fixed to the support 10
Since the engagement hole 17 and the locking part 22 formed at the tip of the bush 20 are fitted, the bush 20
is slidably fitted into the pivot 7 without rotating between the support 10 and the plate 15. By tightening the plate 15 formed of spring material to the support 10 with the screws 30, an appropriate fitting torque is applied between the pivot 7, the bush 20, and the support 10, making it easy to adjust the reflection angle of the mirror while driving. It never shifts.

Furthermore, when driving at night, if the lights of a following car are dazzling, the lever 26 can be switched to instantly change the reflection angle of the mirror. At this time, since the reflection angle of the mirror is changed only in one direction using the lever 26, if there are no cars following, the lever 26
If you return it to its original state, you can instantly return to the original reflection angle again, and there is no need to readjust the reflection angle of the mirror.
