Claims

[Scope of utility model registration request]

In electric stay retractable mirrors, in which the stay that holds the mirror is rotated by a motor to position the mirror in the use or storage position, two microswitches are used to detect the use and storage positions of the stay and control the motor. are stacked in two stages along the output shaft of the drive unit connected to the stay, and a cylindrical cam equipped with a cam ridge that can press each push button of the micro switch at a different predetermined position. , a stay position detection device for an electric stay retractable mirror that is integrally attached to the output shaft;
