[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rearview mirror for a vehicle which can be mainly applied to a door mirror of an automobile.

[0002]

2. Description of the Related Art Conventionally, as an automobile door mirror, FIG.
4 to 4 are generally known. FIG. 3 is a front view of the door mirror, and FIG. 4 is an enlarged sectional view taken along line XX of FIG. The automobile door mirror includes a mirror base body A fixedly supported on the vehicle body side, a mirror housing B rotatably supported by the mirror base body A, and a mirror housing B inside the mirror housing B and integrated with the mirror housing. And a unit bracket C coupled to the main component.

[0003] The mirror base body A comprises a seat portion 1 and a tubular shaft portion 2 for inserting an electric cord which stands on the upper surface thereof.
The seat 1 is fixed to the vehicle body by bolts 3. Reference numeral 4 denotes a base cover, which is fixed to the seat 1 of the mirror base body A by screws 5.

A unit bracket C in the mirror housing B supports a motor drive mechanism for adjusting the direction of the mirror 6 from outside. One end of the unit bracket C has a cylindrical shaft portion 2 of the mirror base body A. The mirror base body A has a sleeve portion 7 surrounding the lower portion. The mirror base body A is rotatably supported on the seat portion 1 around the cylindrical shaft portion 2. Reference numeral 8 denotes a ball placed between the sleeve portion 7 and the seat portion 1 to make the rotation smooth and secure the rotation angle position. The ball 8 is provided at the upper end of the sleeve portion 7 and the cylindrical shaft portion 2. Bush nut 9 provided
A coil spring 10 for elastically pressing and holding the sleeve portion 7 toward the seat portion 1 is provided between the coil spring 10 and the coil spring 10.

The sleeve portion 7 of the unit bracket C
, The mirror housing B is fixed with the screw 11,
It is integrated. Reference numeral 12 denotes an electric cord inserted through the cylindrical shaft portion 2, one of which is connected to a control circuit including a power supply, and the other of which is connected to a motor drive mechanism supported by the unit bracket C.

In the door mirror having the above-described structure, the mirror housing B can be manually turned around the shaft 2 of the mirror base body A together with the unit bracket C. Further, the direction of the mirror 6 can be externally adjusted via a motor drive mechanism supported by the unit bracket C.

[0007]

If a rearview mirror for a vehicle (including a door mirror) is subjected to strong vibrations, especially during high-speed running, the rearward visibility of the mirror is significantly impaired by the vibrations. In the configuration of the door mirror illustrated in FIGS. 3 and 4, the unit bracket C that indirectly supports the mirror 6 is supported only by the lower half of the cylindrical shaft portion 2 of the mirror base body A. It is easy to rattle and is easily affected by vibration of the vehicle body with respect to the mirror.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the conventional vehicle rearview mirror.
It is an object of the present invention to provide a vehicle rearview mirror capable of minimizing the influence of vehicle vibration on a mirror and improving rear visibility.

[0009]

According to the present invention, one end of a unit bracket for supporting a mirror is supported by a shaft provided on a mirror base body via a motor driving mechanism. In a rearview mirror for a vehicle configured by attaching a housing to the unit bracket and attaching a base cover to the mirror base body, a lower portion provided on the unit bracket at a shaft portion of the mirror base body and surrounding a lower portion of the shaft portion. The gist has a configuration in which a sleeve and an upper sleeve fitted on the upper part of the shaft portion are rotatably supported.

[0010]

According to the structure in which the unit bracket for indirectly supporting the mirror is supported by the upper and lower ends of the shaft of the mirror base body as described above, the influence of the vibration of the vehicle body on the mirror is minimized. Can be suppressed.

[0011]

1 shows an embodiment of the present invention. The same or similar members as those in FIGS. 3 and 4 are denoted by the same reference numerals. That is, the vehicle door mirror according to the present embodiment includes a mirror base body A fixedly supported on the vehicle body side and a mirror housing B rotatably supported by the mirror base body A.
And a unit bracket C in the mirror housing B, which is integrally connected to the mirror housing.

The mirror base body A comprises a seat portion 1 and a tubular shaft portion 2 for inserting an electric cord which stands on the upper surface thereof.
The seat 1 is fixed to the vehicle body by bolts 3. Reference numeral 4 denotes a base cover, which is fixed to the seat 1 of the mirror base body A by screws 5.

At one end of the unit bracket C,
It has a sleeve part 7 surrounding the lower part of the cylindrical shaft part 2 and a sleeve part 13 fitted inside the upper part of the cylindrical shaft part 2, and the unit bracket C is connected to the shaft through both the sleeve parts 7 and 13. The part 2 is rotatably supported.

Reference numeral 8 designates a sleeve portion 7 for smooth rotation of the mirror base body A and for ensuring a rotation angle position.
Between the sleeve portion 7 and the bush nut 9 provided at the upper end of the shaft portion 2, the sleeve portion 7 is elastically pressed and supported on the seat portion 1. A coil spring 10 is provided.

According to the structure in which the upper and lower ends of the cylindrical shaft portion 2 serving as the rotation center of the unit bracket C are supported by the sleeve portions 7 and 13 as described above, rattling is eliminated, and the unit bracket C is cooperated with the spring 10. The effect of vehicle body vibration on the mirror is minimized.

In the above embodiment, the upper sleeve portion 13 is configured to support the cylindrical shaft portion 2 inside thereof. However, the upper sleeve portion 13 may be supported outside the cylindrical shaft portion 2 or may be a separate member. It may be configured to be connected to the unit bracket side. Further, the cylindrical shaft portion 2 may be a simple shaft portion, and the electric cord may be inserted into another place.

[0017]

As described above, according to the present invention, since the unit bracket for supporting the mirror is supported at the upper and lower ends of the shaft of the mirror base body, vibration of the vehicle body with respect to the mirror is reduced. A rearview mirror that can minimize the influence is obtained.
