Claims

[Scope of utility model registration request]

A base fixed to the door, a fixed shaft provided on the base, a mirror housing rotatably supported around the fixed shaft and holding the mirror in an adjustable manner, and provided within the housing, A housing drive mechanism in which a drive motor drives a planetary gear meshing with a fixed gear pivotally supported on the fixed shaft by a drive motor via a reduction mechanism; The electric folding door mirror is equipped with a clutch mechanism that absorbs a load, and the clutch mechanism includes a driving side member and a driven side member that are pressed against each other by an elastic means, and the pressing surface of these members is Among them, four clutch grooves are formed on one side, and
On the other hand, one to four clutch pawls are formed to fit into each of the clutch grooves, and a clutch pawl engages each clutch groove every time the driven side member rotates a quarter of a rotation with respect to the driving side member. Electrically foldable door mirrors that are designed to fit together.
