Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle rearview mirror.

[0002]

2. Description of the Related Art As a vehicle rear-view mirror, for example, an inside rear-view mirror mounted inside a vehicle is
For example, there is a structure shown in Japanese Utility Model Publication No. 2-60045. A rearview mirror for a vehicle having such a structure comprises a mirror body made of a glass material and having a mirror surface, an opening formed by housing the mirror body and exposing the mirror surface side of the mirror body, and the opening. At least a peripheral portion of the mirror main body is formed of a synthetic resin mirror holder that holds the periphery of the mirror body.

[0003]

However, in such a conventional technique, it is conceivable to change the mirror body from glass to synthetic resin in order to reduce the weight of the rearview mirror. Since the holder is also made of synthetic resin, the flat mirror body may be bent due to a difference in thermal contraction between the mirror body and the mirror holder, which may cause distortion. As a countermeasure against this, if a gap is formed between the two so that the load is not applied to the mirror body, there is a possibility that chatter vibration may occur between the periphery of the opening of the mirror holder and the mirror body. There is.

The present invention has been made by paying attention to such a conventional technique, and is intended to reduce the weight and prevent the chatter vibration from being transmitted between the mirror body made of synthetic resin and the mirror holder. Is provided.

[0005]

The invention according to claim 1 is
A mirror main body made of synthetic resin having a mirror surface, and an opening for accommodating and holding the mirror main body and exposing the mirror surface side of the mirror main body are formed, and a peripheral portion of the opening is a peripheral portion of the mirror main body. A rear-view mirror for a vehicle comprising at least a synthetic resin mirror holder for holding a frictional resistance means at a peripheral portion of a mirror surface of a mirror body facing a peripheral portion of an opening of the mirror holder. Is formed.

According to the first aspect of the present invention, the frictional resistance means is formed in the peripheral portion of the mirror surface of the mirror body facing the peripheral portion of the opening of the mirror holder. Even if chatter vibration occurs in the peripheral portion of the opening of the mirror holder, since the peripheral portion of the mirror body has an uneven shape, fine vibration is not absorbed and transmitted. Since the mirror body is made of synthetic resin, the weight can be reduced.

According to a second aspect of the present invention, there is provided the vehicle rear-view mirror according to the first aspect, wherein the frictional resistance means is formed at a portion opposite to a gate position when the mirror body is molded. Become.

According to the second aspect of the invention, the mirror surface tends to be distorted due to a temperature difference and a pressure difference with the gate at the portion opposite to the gate at the time of molding the mirror body. Since the frictional resistance means is formed at the portion where the strain is likely to occur, the strain is less visible and the appearance is improved.

A third aspect of the present invention is the vehicle rearview mirror according to the first or second aspect, wherein the frictional resistance means has a roughened mirror surface.

According to the third aspect of the invention, the distortion can be made less visible by making the mirror surface a rough surface.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention will be described below with reference to FIGS.

An inside mirror 1 as a "vehicle rearview mirror" comprises a mirror body 3 made of synthetic resin having a mirror surface 2, a mirror body 3 housed and held therein, and the mirror body 2 side of the mirror body 3 is exposed. A mirror holder 5 made of synthetic resin, in which an opening 4 is formed and the peripheral portion of the opening 4 holds the peripheral portion 8 of the mirror body 3.
And an appropriate portion of the vehicle body, for example, an inner surface of the front window panel, which is rotatably supported by an engaging portion (not shown) formed on the rear surface side (front side of the vehicle) of the mirror holder 5. And a stay 6 held by Reference numeral 11 is a vapor deposition process performed on the back surface of the mirror body 3.

Friction resistance means 9 is formed on the peripheral portion 8 of the mirror surface 2 of the mirror body 3 facing the peripheral portion of the opening 4 of the mirror holder 5. On the inner surface of the mirror holder 5, ribs 7 capable of holding the mirror body 3 from the back surface side are provided upright.

The friction resistance means 9 is used for the mirror body 3
It is formed around the mirror surface 2 side of the peripheral portion 8 of
The mirror body 3 is always formed at a portion opposite to the position of the gate 10 at the time of molding. That is, as shown in FIG. 2, since the central upper portion of the mirror body 3 is located at the gate 10, the mirror body 3 is always formed on the opposite left and right end portions.

The frictional resistance means 9 applies a contact pressure by a spring or hydraulic pressure to several square rod-shaped fine-grained grindstones that are in surface contact (or line contact) generally called honing, and rotate the honing head. However, the mirror surface 2 is made rough by drawing a diagonal line with respect to the mirror surface 2 and drawing a cross hatch line by the reciprocating motion.

Since the configuration of this embodiment is as described above,
Since the friction resistance means 9 is formed in the peripheral portion 8 of the mirror surface 2 of the mirror body 3 facing the peripheral portion of the opening 4 of the mirror holder 5, the opening 4 of the mirror holder 5 is caused by the vibration accompanying traveling of the vehicle. Even if chattering vibration occurs in the peripheral part of the, the peripheral part 8 of the mirror surface 2 of the mirror main body 3 does not have a smooth surface shape but has an uneven surface shape, and therefore fine vibrations are not absorbed and transmitted. .

Further, since the frictional resistance means 9 is formed at a portion opposite to the position where the gate 10 is provided when the mirror body 3 is formed, the frictional resistance means 9 is formed on the gate 10 when the mirror body 3 is formed. The mirror surface 2 tends to be distorted at a portion on the opposite side to the position where it is provided due to a temperature difference or a pressure difference from the gate 10. However, the friction resistance means 9 is formed at the portion where the distortion is likely to occur. As a result, the distortion is less visible and the appearance is improved.

Further, the friction resistance means 9 is provided with the mirror surface 2
Since the surface is roughened, the distortion becomes more difficult to see.

In the above embodiment, the "rear mirror" is limited to the inside mirror, but the invention is not limited to this, and the outside mirror may be used. Further, although the “rear mirror for vehicle” has been described as the rear mirror for automobile, the present invention is not limited to this.
It may be a train.

[0020]

According to the first aspect of the present invention, since frictional resistance means is formed in the peripheral portion of the mirror surface of the mirror body facing the peripheral portion of the opening of the mirror holder, vibrations associated with vehicle running are generated. Therefore, even if chatter vibration occurs in the peripheral portion of the opening of the mirror holder, since the peripheral portion of the mirror surface of the mirror body has an uneven surface shape, fine vibration is not absorbed and transmitted.

According to the second aspect of the present invention, the mirror surface tends to be distorted at the portion opposite to the gate position at the time of molding the mirror body due to a temperature difference or a pressure difference from the gate. Since the frictional resistance means is formed at the portion where the strain is likely to occur, the strain is less visible and the appearance is improved.

According to the third aspect of the invention, since the mirror surface is roughened, the distortion is more difficult to see.
