Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vibration isolating device for a door mirror whose angle can be changed.

(Prior Art) When a vehicle is traveling at high speed or on a rough road, the door mirrors vibrate, making it difficult to see the rear view.

For this reason, some conventional door mirrors attached to door panels have been designed to prevent vibration of the door mirror by disposing a vibration-proofing elastic body between the door mirror housing and the door panel at a position where the two are closest to each other.

(Problem to be solved by the invention) However, when this conventional technology is used for a door mirror that can be folded around a single axis, the elastic body for vibration isolation becomes visible when the door mirror is not in use, and the rotation of the door mirror becomes difficult. This causes problems such as noticeable scratches on the door panel or door mirror housing.

Therefore, in order to eliminate these problems, it is possible to prevent the vibration of the door mirror by increasing the degree of contact between the support part that rotatably supports the door mirror housing and the support part with the door mirror housing. In order to do this, it is necessary to increase the precision of the machining dimensions of both parts, which poses a problem in that the manufacturing cost of the door mirror increases.

Therefore, the present invention provides a vibration isolator in which scratches and the like are difficult to see without increasing processing accuracy.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a substantially L-shaped structure that is fixed to the vehicle body and has a horizontal surface having a rotation axis and an upright portion that rises from the horizontal surface. a housing side member that accommodates a mirror and is rotatably supported by the rotation shaft on the horizontal plane; and a housing side member that is provided between the housing side member and the base member, and that is provided between the housing side member and the base member. In a door mirror comprising a clutch mechanism for positioning with respect to a base member, a position away from the rotation axis between the horizontal upper surface of the base side member and the lower surface of the housing side member, and which becomes an overlapping portion when the door mirror is used. It is characterized in that an abutting member is interposed at the position.

(Embodiments) Preferred embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a front view of the door mirror according to the present invention in its use position, FIG. 2 is a plan view, and FIG. 3 is a partially cutaway detailed view of the door mirror rotating portion.

The door mirror 1 has a substantially L-shape in which a mirror 3 is housed in a mirror housing 2 which is substantially rectangular in front and formed in the shape of a case with a front opening, and this mirror housing 2 is fixed to the front part of a door window of a vehicle (not shown). It is rotatably supported on the base member 4.

The mirror rotating section 5, which is this supporting section, is driven by a driving source 6.
A locking mechanism for fixing the mirror housing 2 in each of these fixed positions and a locking mechanism for the locking mechanism are provided. A release device 7 is provided.

The structure of the mirror rotation unit 5 is such that a mirror mounting member 10 is freely rotatable with respect to a support substrate 8 on the upper surface of the base member 4 from above a bearing hole 9 provided in this substrate 8 via a washer member (not shown). insert. The mirror mounting member 10 has a mounting part 10a attached to the bottom surface of the mirror housing 2 at the top, a shaft part 10b rotatably supported by the bearing hole 9 of the substrate 8, and a shaft part 10b which is integrally formed in the center of the lower part. It consists of a shaft portion 11 to be inserted.

On the other hand, a clutch spring 12, displacement members 13, 14,
The clutch balls 15, . The clutch plate 16 and the displacement member 14 are pressed into contact by the elastic force of the clutch spring 12 via clutch balls 15, . . . housed in recesses provided on opposing surfaces, respectively. Therefore, the clutch plate 16 rotates following the displacement member 14, and constitutes a clutch mechanism that idles relative to the displacement member 14 when an external force of a certain magnitude or more is applied to the clutch plate 16.

Now, when the mirror housing 2 is rotatably supported on the base member 4 with such a configuration, depending on the machining dimensional accuracy of the shaft portion 10b of the mirror mounting member 10 and the support substrate 8 that supports it, the vehicle When traveling at high speeds or on rough roads, the door mirror 1 begins to vibrate around this support portion.

Therefore, the present invention provides an abutment member 2 between the support substrate 8, which is the top surface of the base member 4, and the bottom surface of the mirror housing 2.
Interpose 0. The abutment member 20 is fixed in a substantially ring shape on the support substrate 8 at a position away from the center of rotation of the mirror housing 4 and at a position that becomes an overlapping portion when the door mirror 1 is used. This contact member 20 may be formed integrally with the support substrate 8,
Alternatively, it may be formed of an elastic body such as rubber.

Note that the abutment member 20 is not limited to a substantially ring shape;
It may be a plurality of pin-shaped or hemispherical members that serve as point contacts.

(Effect of the invention) As is clear from the above explanation, according to the invention, the part between the upper surface of the base member and the lower surface of the housing member, which is spaced apart from the center of rotation of the housing member and becomes an overlapping part when the door mirror is used. Since the abutting part is interposed in the door mirror, there is no need for high precision in the bearing part, etc., vibration of the door mirror can be prevented, and the abutting member etc. are not noticeable even when the door mirror is not in use. In addition, in the present invention, since the abutment member is formed between the upper surface of the base side member and the lower surface of the housing side member, the assembly work when attaching the housing to the base member side is easy and accuracy is not required, making it easy to manufacture door mirrors. becomes easier. Moreover, since there are no uneven parts on the facing surfaces of the base member and the housing, the appearance is also improved.

In addition, by constructing the abutment member from an elastic body (elastic member) as in this embodiment, it can follow the wear of other members and sufficiently achieve the purpose even if the manufacturing accuracy, installation accuracy, etc. of the abutment member are low. can,
Manufacturing costs can be lowered.
