とがなく、又、ミラー本体の下動による圧力でさ
らに内部に侵入してしまうこともある。(Problem to be solved by the invention) However, in such a folding vehicle mirror, when the mirror body moves slightly upward relative to the base member, negative pressure is generated between the mirror body and the base member.
For example, if water droplets adhere to the edges of the opposing surfaces between the base member and the mirror body during rainy weather, these water droplets will enter between the mirror body and the base member due to negative pressure.
Once this water has entered, it does not easily come out, and may further enter the interior due to the pressure caused by the downward movement of the mirror body.
