摘要：
In a mirror supporting apparatus, a lever pivots the center of gravity of the mirror, whereby performing exactly the same motion with respect to a mirror provided with a universal joint at the center of gravity of the mirror. Therefore, the same effect as that of conventional mechanism is obtained without provision of a hole in the mirror. Furthermore, a counter weight is secured to the mirror so as to position a substantial center of gravity of the mirror outside of the mirror, whereby obtaining a similar effect.
