Vehicle door mirror
In a vehicle door mirror, an electric retraction unit is disposed between a mirror housing and a shaft pivotably supporting a base end part of the mirror housing, and at least three housing fastening parts are fastened to the mirror housing and provided integrally with a unit constituent member forming part of the electric retraction unit. A vibration suppression arm part is provided integrally with the unit constituent member and extends in a direction that goes away from at least two of the at least three housing fastening parts. A remaining one housing fastening part of the at least three housing fastening parts is formed in a tip end part of the vibration suppression arm part. Accordingly, the vehicle door mirror can give an effective vibration suppression effect while enhancing the workability and suppressing any increase in the cost.

4. The vehicle door mirror according to claim 1 , wherein
a base part of the vibration suppression arm part is integrally and connectedly provided on the unit constituent member in a vicinity of a specific housing fastening part of the at least three housing fastening parts other than the housing fastening part that is formed in the tip end part of the vibration suppression arm part, and
the specific housing fastening part is fastened to the mirror housing by means of a pair of upper and lower screw members.
5. The vehicle door mirror according to claim 2 , wherein
a base part of the vibration suppression arm part is integrally and connectedly provided on the unit constituent member in a vicinity of a specific housing fastening part of the at least three housing fastening parts other than the housing fastening part that is formed in the tip end part of the vibration suppression arm part, and
the specific housing fastening part is fastened to the mirror housing by means of a pair of upper and lower screw members.
6. The vehicle door mirror according to claim 3 , wherein
a base part of the vibration suppression arm part is integrally and connectedly provided on the unit constituent member in a vicinity of a specific housing fastening part of the at least three housing fastening parts other than the housing fastening part that is formed in the tip end part of the vibration suppression arm part, and
the specific housing fastening part is fastened to the mirror housing by means of a pair of upper and lower screw members.
7. The vehicle door mirror of claim 1 , wherein the gear case has a plurality of engagement claws protruding outwardly and projectingly provided on an upper part thereof, and wherein the electric retraction unit further comprises a cover that is removably joined to the gear case so as to cover the gear case from above, and wherein the cover has a plurality of latching holes formed therein which receive the engagement claws of the gear case.
8. A vehicle door mirror comprising
a mirror housing that has a mirror housing recess housing a mirror,
a base member that is configured to be mounted on a side door of a vehicle,
a shaft that is standingly provided on the base member so as to pivotably support a base end part of the mirror housing,
and
an electric retraction unit that is disposed between the shaft and the mirror housing so as to pivot the mirror housing around an axis of the shaft, the electric retraction unit comprising a gear case which forms the unit constituent member and surrounds part of the shaft,
at least three housing fastening parts being fastened to the mirror housing and provided integrally with a unit constituent member forming part of the electric retraction unit,
wherein a vibration suppression arm part is provided integrally with the unit constituent member and has a base part which is integrally and connectedly provided on the gear case, the vibration suppression arm part extending in a direction that goes away from at least two of the at least three housing fastening parts, wherein the vibration suppression arm part is formed so as to have a bent portion in an intermediate part thereof, and
wherein a remaining one housing fastening part of the at least three housing fastening parts is formed in a tip end part of the vibration suppression arm part,
wherein a mirror angle adjustment unit that can make the mirror tilt is fixed within the mirror housing, and wherein the bent portion is formed so as to bend toward a side on which overlapping the mirror angle adjustment unit is avoided when viewed from a vehicle fore-and-aft direction in a state in which the mirror housing is present at a raised position in which the mirror housing is to protrude sideways from the side door.
9. The vehicle door mirror of claim 8 , wherein the gear case has a plurality of engagement claws protruding outwardly and projectingly provided on an upper part thereof, and wherein the electric retraction unit further comprises a cover that is removably joined to the gear case so as to cover the gear case from above, and wherein the cover has a plurality of latching holes formed therein which receive the engagement claws of the gear case.
