To improve getting on/off performance at a vehicle entrance in a vehicle door opening/closing mechanism.SOLUTION: A vehicle door opening/closing mechanism 10 is configured to guide a vehicle door 3 in a movable manner between a closed position in which a vehicle entrance is closed and an open position in which the door is opened. The opening/closing mechanism 10 includes: a hinge arm 12 whose one end is rotatably supported by a vehicle body-side rotating shaft 5 of a vehicle, whose the other end is rotatably supported by a door-side rotating shaft 6, and which is provided with a drive arm 13 to extend from the other end; and a telescopic drive unit 31 which has a unit case 32 which is arranged inside the door to be rotatably supported by a support shaft 59 whose one end is fixed to the door and a telescopic movement part 40 which goes in and out of the unit case 32 and whose tip is rotatably fixed to a tip of the drive arm 13. The telescopic drive unit 31 drives the telescopic movement part 40 in and out of the unit case 32 by a drive motor and a power direction changing mechanism.SELECTED DRAWING: Figure 7

    【課題】車両ドアの開閉機構において、車両乗降口における乗降性を向上させる。【解決手段】車両ドアの開閉機構10は、車両ドア3を、車両乗降口を閉じている閉止位置と、ドアを開く開放位置間を移動可能にガイドする。開閉機構10は、車両の車体側回転軸5に一端が回転支持され、ドア側回転軸6に他端が回転支持され、他端側から駆動アーム13が延設されているヒンジアーム12と、ドアの内部に配設され、その一端がドアに固定された支持軸59に回転支持されたユニットケース32と、ユニットケース32に出入すると共に、その先端が駆動アーム13の先端に回動可能に固定されている伸縮可動部40とを有する伸縮駆動ユニット31と、を含む。伸縮駆動ユニット31は、駆動モータと動力方向変換機構とにより、伸縮可動部40をユニットケース32から出入駆動する。【選択図】図7
