A common base for manually retractable and electrically retractable vehicle door mirrors, the common base comprising:
- a car body fixing section configured to be attached to an outer side of a car body, and
- a rotation support section which is integral with the car body fixing section and is configured to rotatably support a mirror rotating member of one of an electrically retractable door mirror and a manually retractable door mirror, the rotation support section being configured to move the mirror rotating member of the one of the electrically retractable door mirror and the manually retractable door mirror between a retracted position and a return position,
- the common base further comprising on an upper side of the rotation support section:
- an upright shaft fastening surface that is configured to fasten a rotatable shaft for the mirror rotating member of the electrically retractable door mirror;
- a center hole formed in a center of the upright shaft fastening surface,
- the center hole, when the common base is used for the manually retractable door mirror, being configured to rotatably pass a rotatable shaft of the mirror rotating member of the manually retractable door mirror that is formed along a rotation axis of the mirror rotating member of the manually retractable door mirror and protrudes downward from a bottom side of the mirror rotating member of the manually retractable door mirror,
- the center hole, when the common base is used for the electrically retractable door mirror, being configured to pass a harness drawn downward through the rotatable shaft of the mirror rotating member of the electrically retractable door mirror;
- and
- an annular wall housing groove formed into a circular shape coaxially with the center hole on an outer circumferential side of the center hole and configured to rotatably house an annular wall of the mirror rotating member of the manually retractable door mirror when the common base is used for the manually retractable door mirror, and wherein
- the annular wall housing groove is configured to be placed coaxially with the rotatable shaft of the mirror rotating member of the manually retractable door mirror at a location on an outer circumferential side of the rotatable shaft of the mirror rotating member of the manually retractable door mirror.
