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, the stay is equipped with a micro switch that detects the use and storage positions of the stay and controls the motor. A cylindrical cam is disposed opposite to the output shaft of a drive unit connected to the output shaft, and is integrally attached to the output shaft, and has a cam groove that allows the push button of the microswitch to operate at different predetermined positions. Electric stay retractable mirror.
