Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rearview mirror that is attached to a vehicle.

[Prior art] Conventional inner mirrors have a ball joint at the tip of the stay so that the reflection angle of the mirror can be set freely, and the mirror body is rotatably attached to the ball joint. . In this case, a gripping member that fits and holds the pivot forming a part of the ball joint is provided inside the mirror body, and the gripping member is provided with a screw that can adjust the fitting torque of the pivot (for example, Tokuko Showa 53-22329
issue).

By the way, the conventional mirror is provided with an adjusting screw 20 that can be operated from outside the mirror body so that the fitting torque of the pivot can be adjusted even after the mirror is assembled. That is, as shown in FIG. 3, after the mirror is fitted, it is impossible to insert the adjustment screw 20 into the pivot gripping member 22 inside the body from the mirror surface side, or to adjust the torque of the gripping member. Therefore, in order to enable fine adjustment of the torque after assembly, the screw 20 is inserted into the gripping member from the rear, and an adjustment hole 24 is provided at the back of the body 23 into which a tool such as a screwdriver can be inserted. , and this adjustment hole 2
The head 25 of the screw is made to face 4.

However, normally, when assembling this type of torque adjustment mechanism, before fitting the mirror, the pivot of the stay inserted into the body from the body opening side is inserted into a gripping member that forms a housing space for the pivot, and the A screw is inserted into the member, and the tightening force of the screw temporarily fixes the pivot and the gripping member. Therefore, the assembler must turn the body over and tighten the screw from the back side. This is troublesome in terms of man-hours, reduces work efficiency, and increases work costs.
It is disadvantageous. In addition, it was necessary to form a large adjustment hole on the back of the body, resulting in an unsightly appearance.

[Purpose of the invention The present invention is proposed in order to improve the conventional problems as described above, and by devising the structure of the screw end of the torque adjustment screw, it is possible to assemble and pivot the torque adjustment mechanism. To provide a device in which the screw can be inserted into the gripping member from the body opening side, and fine adjustment of the pivot torque after assembly can be easily performed from the screw end.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rear mirror in which a mirror body with a mirror attached to the front opening is attached to the vehicle via a ball joint and a stay. A gripping member is provided inside the body with a torque adjustment screw to adjust the fitting and holding force for the ball joint, and the screw end of the adjustment screw is provided with an engagement groove or protrusion for a jig. , the head of this adjustment screw faces the opening side of the mirror body, and the screw end faces a small hole for inserting a tool formed on the back surface of the mirror body.

[Example] Next, an example of the present invention will be specifically described with reference to the drawings.

Figure 1 is a sectional view showing the main structure of the present invention, in which 1 is a mirror body, 2 is a mirror fitted into the front of the body, 3 is a stay, and 4 is formed at the tip of the stay. It is a pivot and is arranged inside the body 1. Reference numerals 5 and 6 are a pair of gripping members that form a seat that fits and holds the pivot, and are arranged to be expandable and retractable. Reference numerals 7 and 8 denote a pair of support members arranged outside the gripping member to apply a tightening force to the gripping member, and a pair of opposing tongue pieces 9 and 1 having screw mounting holes at their lower ends.
0 is set. Reference numeral 11 is a pivot fitting torque adjustment screw that connects the opposing tongue pieces 9 and 10.

In the present invention, the head 12 of the adjustment screw faces the opening side of the mirror body 1, and the end surface of the screw end 13 has a hexagonal hole, a hexagonal protrusion, or a slotted hole, as illustrated in FIG. After providing an engaging groove 14 for a jig or a plus-shaped tool, the screw end is made to face a small hole 15 for inserting a tool formed on the back surface of the mirror body.

[Effects of the invention] Since the present invention has the configuration as explained in the embodiments above, all the work of assembling the torque adjustment mechanism in the mirror body can be done from the body opening side, and the body can be assembled one by one. There is no need to turn it over, improving work efficiency during assembly, and torque adjustment after fitting the mirror glass can be easily done from the back side of the body using the engagement groove and engagement protrusion formed on the screw end. be able to.

In addition, the adjustment hole on the back of the body can be small enough to operate the screw end, which has the advantage of not damaging the appearance of the body.
