PROBLEM TO BE SOLVED: To provide a vehicle room mirror capable of preventing generation of impact sound when changing an angle of a display surface caused by backlash provided to gear trains, and excellent in silence property.SOLUTION: A vehicle room mirror includes a housing, a mirror, a cam shaft, a fixation part, and a driving part. The cam shaft rotates by driving force transmitted from the driving part, and a movable part including the housing, the mirror, and the driving part generally tilts accompanied by moving to the fixation part by the action of the cam. The driving part includes a driving source, and gear trains including a first gear disposed on the cam shaft and a second gear engaged with the first gear, and transmitting the driving force of the driving source to the cam shaft. The second gear is elastically engaged with the first gear.SELECTED DRAWING: Figure 7

    【課題】ギア列に設けられるバックラッシュに起因する表示面の角度変更時の衝撃音の発生を防止できる、静音性に優れる車両用ルームミラーを提供する。【解決手段】車両用ルームミラーは、筐体と、ミラーと、カムシャフトと、固定部と、駆動部とを備える。駆動部から伝達される駆動力により、カムシャフトが回転し、カムの作用により固定部に対して移動することに伴い、筐体、ミラー及び駆動部を含む可動部が全体的に傾動する。駆動部は、駆動源と、カムシャフトに配置される第1ギア及び第1ギアに噛み合う第2ギアを含み、駆動源の駆動力をカムシャフトに伝達するギア列と、を有する。第2ギアは、第1ギアに対して、弾性的に噛み合う。【選択図】図7
