Problems solved by technology

[0006] However, in the conventional interior rearview mirror for automobiles for rear installation, after the annular portion 11 of the spring 10 is fitted with the protrusion 9 during assembly, in order to prevent the spring 10 from falling out, The fixture 13 must be firmly connected to the raised portion 9, thereby increasing the manufacturing process of this part and increasing the number of parts of the fixture 13

[0007] Also, since the cushioning material 14 is fixed on the lower jaw 4 by using a double-sided tape, the number of parts of the double-sided tape part is increased, and when assembling the interior rearview mirror, the adhesive surface of the protective double-sided tape is peeled off. The cover is very troublesome, and the deterioration of the adhesive part of the double-sided tape caused by heat during the use of the interior rearview mirror of an automobile may sometimes cause the cushioning material 14 to peel off from the lower jaw 4.

[0008] Also, if the fixture 13 is not used but Figure 19 In the shown structure, a flange portion 15 protruding outward in the radial direction is provided on the front end of the outer peripheral surface of the raised portion 9 to prevent the spring 10 fitted with the raised portion 9 from falling off, although parts can also be reduced. number, but when the annular portion 11 of the spring 10 is fitted with the protruding portion 9, it is necessary to provide a process of enlarging the inner diameter of the annular portion 11 of the spring 10, which increases the manufacturing process.
