の電動可倒式ドアミラー。[Scope of Claim for Utility Model Registration] (1) A base fixed to the door, a fixed shaft provided on this base, and a mirror supported rotatably around this fixed shaft and holding a mirror adjustable. An electrically foldable door mirror comprising a mirror housing and a housing drive mechanism that drives a planetary gear provided in the housing and meshed with a fixed gear supported by the fixed shaft by a drive motor via a reduction mechanism. The mounting shaft through which the planetary gear is rotatably inserted is formed with a diameter reducing groove in the direction around the axis, and a push nut is fitted into the diameter reducing groove to prevent the planetary gear from slipping out. Electrically foldable door mirrors. (2) The push nut has a plurality of substantially U-shaped slits radially cut out in the outer diameter direction from a fitting hole formed in the center and into which the mounting shaft is inserted, so that the mounting shaft can be inserted into the push nut. An electrically foldable door mirror according to claim 1, which is formed with a plurality of elastic tongues that press against the outer periphery of the mirror. (3) At least one of the elastic tongues of the push nut is formed longer than the other elastic tongues, and the long elastic tongue is axially locked to the mounting shaft. An electrically foldable door mirror according to claim 1 or 2, which is formed with a locking portion.
