To secure relatively easily an installation site of a driving source by separating the installation site of the driving source from a base end side of a driving arm.SOLUTION: The base ends of a driving arm 2 and a follower arm 3 having the same radius of rotation are pivotally attached to the lower part of a vehicle step S, and the tips of the driving arm 2 and the follower arm 3 are pivotally attached to the bottom of a step board 1. The step board 1 is provided so as to freely reciprocate on the same horizontal plane between a storage position X in the lower part of the vehicle step S and an overhang position Y at the lower front of the vehicle step S, and the driving arm 2 is connected to the driving source 8 via power transmission means 9. The power transmission means 9 comprises a rack 10 meshed with a driving gear 8a provided in the driving source 8 and advancing/retreating in the front and back direction L of a vehicle, and a machine element 11 for converting the reciprocating linear motion of the rack 10 to the reciprocating oscillation of the driving arm 2.SELECTED DRAWING: Figure 1
【課題】駆動源の設置箇所を駆動アームの基端側より離間させて駆動源の設置箇所を比較的容易に確保する。【解決手段】車両ステップS下部に、回転半径が同一な駆動アーム2と従動アーム3の基端を枢着すると共に、駆動アーム2と従動アーム3の先端を踏板1の底部に枢着し、該踏板1を車両ステップS下部の格納位置Xと車両ステップS下部前方の張出位置Yとの間を同一水平面上で往復移動自在に設け、駆動アーム2は駆動源8に伝動手段9を介して連繋し、該伝動手段9は、駆動源8に設けた駆動歯車8aに噛合して車両の前後方向Lに進退するラック10と、該ラック10の往復直線運動を駆動アーム2の往復揺動に変換する機素11とから構成する。【選択図】図1
