2. Description of the Related Art In a conventional vehicle mirror device, in particular, in a door mirror device, a coupling structure between a mirror holder for holding a mirror and a pivot plate provided at an actuator is, for example, a structure as shown in FIG. Has become. In this device, an engagement receiving portion 110 formed of a concave groove (concave groove) is provided on the back side of the mirror holder 10 to which the mirror is attached and at four corners of a quadrilateral. On the pivot plate 20 side coupled with the mirror holder 10, the engagement receiving portions are formed so as to correspond to the engagement receiving portions 110 of the mirror holder 10 and form four corners of a quadrilateral. The engagement shaft portion 210 that engages with the concave groove of
In this case, the shaft portions are provided so as to be parallel to each other. Each of the engagement shaft portions 210 on the pivot plate 20 side is connected to the mirror holder 1.
The mirror holder 10 and the pivot plate 2 are recessed in the concave grooves of the respective engagement receiving portions 110 on the zero side.
The connection with 0 is performed.
However, for example, in FIG. 2, the vertical distance between the engagement shaft portions 210 of the pivot plate 20 and the value of Y, which is the vertical distance of the engagement receiving portion 110 of the mirror holder 10 in FIG. If the value of Y ′, which is the distance of
There is a problem that the engagement (coupling) of 0 and 20 is not performed well. Further, in the XX direction, which is the left-right direction, there is no means for regulating the relative positional relationship between the two, and there is a problem that accurate assembly accuracy cannot be obtained. In order to solve such a problem, a structure in which a part of the engagement structure is made different has been developed.
It is publicly known from Japanese Patent No. 51 and the like.

[0003]

In this case, a holding portion having a substantially L-shaped cross section is provided on the mirror holder side, and an engaging shaft portion is provided on the pivot plate side. The configuration is as follows. And
The engagement shaft portion of the pivot plate is inserted into the end portion of the L-shaped holding portion on the mirror holder side in such a manner that the engagement shaft portion is hooked, and further provided in the lower portion of the mirror holder in such a state. Lock claw,
By engaging with a projection provided at the lower end of the pivot plate, the two are connected. However, in such a structure, the relative positional relationship between the two can be regulated, but in assembling, two operations of insertion and insertion and rotation pressing are required, and the assembling efficiency is not good. There is. If the dimensional accuracy between the holding portion and the engagement shaft portion is poor, the dimensional error may make assembly impossible, or conversely, rattling or the like. In order to solve such problems, a concave groove-shaped engagement holding portion is provided on the mirror holder side, while an engagement shaft portion is provided on the pivot plate side, and by appropriately arranging them, SUMMARY OF THE INVENTION It is an object (problem) of the present invention to provide a mirror device for a vehicle in which the assembling process is simplified and the assembling accuracy is improved.

[0004]

Means for Solving the Problems In order to solve the above problems, the present invention takes the following measures. That is, according to the first aspect of the present invention, a mirror holder to which a mirror body is attached, and a pivot plate attached to the actuator so as to be able to oscillate, and a plurality of engagements provided on the pivot plate A shaft portion and a plurality of engagement holding portions provided on the mirror holder are respectively engaged with each other, with respect to a vehicle mirror device having a configuration in which the pivot plate and the mirror holder are engaged with each other. The engagement holding portion provided on the back surface side of the mirror holder is constituted by a concave recess groove into which the engagement shaft portion is inserted, and the arrangement of the engagement holding portion having such a recess groove is arranged. Four states are provided at each corner of the quadrilateral in plan view, and three of them are The direction of the groove is made to have the same direction, the other one is made to face the direction orthogonal to the direction of the three above, while the arrangement of the engaging shaft provided on the pivot plate is changed. And at each corner of the quadrilateral corresponding to the engagement holding portion provided on the mirror holder, three of which are parallel so that the engagement shafts are oriented in the same direction. And the other one has a configuration in which the axial direction of the engaging shaft portion is provided so as to be orthogonal to the above three.

[0005] By adopting such a configuration, the present invention has the following effects.
That is, according to the present invention, the work of connecting the mirror holder to which the mirror is attached and the pivot plate connected to the actuator can be easily performed by one operation from one direction. That is, the pivot plate has four recesses formed on the back side of the mirror holder and four engagement holding portions provided at four corners of the quadrilateral. By pressing the four engagement shafts provided in the above in a state where they are aligned with each other, it becomes possible to engage (join) the two. That is, the connection can be completed by one action of pressing the two. The relative positional relationship between the mirror holder and the pivot plate, particularly in FIG. 1, is determined by three of the four engagement holders and four engagement shafts provided in the same direction. The vertical positional relationship is regulated (positioned). In the left and right direction in which the positional relationship cannot be regulated depending on the three objects, the remaining one (a set of engagement holding portions) formed so that the directions are orthogonal to the three objects. And the engagement shaft) restricts (positions) the positional relationship. With these, all positional relationships in the vertical and horizontal directions are determined, and accurate coupling (assembly) is performed.

Next, the invention according to claim 2 will be described. This is also basically the same as the first aspect. It is characterized in that, in addition to the features described in claim 1, one of the three engagement holding portions provided in the mirror holder, wherein the direction of the recess groove is orthogonal. The slit is formed on the same side as that provided on the side and formed on the side formed substantially parallel to the longitudinal direction of the mirror holder, but around the mounting portion thereof, formed in parallel with the recess groove. Is to be adopted.

By adopting such a configuration, according to the present invention, in addition to the first aspect,
Further, the following operation is exhibited. That is, in coupling the mirror holder and the pivot plate, the action of the slit provided around the engagement holding portion causes the engagement holding portion located at the place where the slit is provided to move with respect to the slit. , It is possible to make a minute displacement (a minute movement) in a direction perpendicular to the direction (the vertical direction in FIG. 1). Due to this minute movement, a slight dimensional error between the engagement holding portion and the engagement shaft portion fitted into the recess groove of the engagement holding portion is absorbed. That is, by the elastic deformation around the slit,
The engagement holding portion itself can move slightly in a direction perpendicular to the direction of the recess groove, and during assembly, the engagement holding portion and the engagement shaft portion absorb a vertical error. It will be engaged in the state where it did. Also, once engaged (coupled), the coupling between the two is more firmly maintained by the spring reaction force due to the elastic deformation around the slit.
