To easily block connection between a drive source and an arm in failure of a drive source or the like, in an overhang state of a step board, and store by manual operation, the step board to a storage position on a lower side of a vehicle step.SOLUTION: Base ends of a drive arm 2 and follower arm 3 whose rotation radii are equal are pivoted to a lower side of a vehicle step S, and tip ends of the drive arm 2 and follower arm 3 are pivoted to a bottom of a step board 1, the step board 1 is provided so as to freely reciprocate in a same horizontal plane between a storage position X on the lower side of the vehicle step S and an overhang position Y on a front side of the lower part of the vehicle step S, the drive arm 2 is connected to the drive source 6 through transmission means 7, the transmission means 7 is formed by pivotally connecting a protrusion piece 8 provided on the base end of the drive arm 2 and protruded to an opposite direction of the drive arm 2 and one end 9a of a rack 9 which engages to a drive gear 6a provided on the drive source 6 and moves forward and retreats in a cross direction A of the vehicle, through a link 10, and a shaft stay 12 having a pivot 11 to which a tip of the link 10 is pivotally supported, is detachably provided on the protrusion piece 8.SELECTED DRAWING: Figure 5

    【課題】踏板の張出状態で、万一駆動源等が故障した場合において、駆動源とアームとの連繋を簡単に遮断し、手動で踏板を車両ステップ下部の格納位置に格納できる様にする。【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6に伝動手段7を介して連繋し、該伝動手段7は、駆動アーム2の基端に該駆動アーム2の反対方向に突設した突片8と、駆動源6に設けた駆動歯車6aに噛合して車両の前後方向Aに進退するラック9の一端9aとを、リンク10を介して枢着連結して成り、該リンク10の先端が軸支される枢軸11を有する軸ステー12を突片8に着脱自在に設ける。【選択図】図5
