To allow a user to recognize a fault without normally actuating a step board by intentionally breaking and chipping a particular part of power transmission means when an overload is added in a storage direction in an overhang state of the step board in the power transmission means for connecting a driving arm and a driving source.SOLUTION: The base ends of a driving arm and a follower arm having the same radius of rotation are pivotally attached to the lower part of a vehicle step, and the tips of the driving arm and the follower arm are pivotally attached to the bottom of a step board. The step board is provided so as to freely reciprocate on the same horizontal plane between a storage position in the lower part of the vehicle step and an overhang position at the lower front of the vehicle step, and the driving arm is connected to the driving source 8 via power transmission means. In the power transmission means, when an overload acts on a rack 10 or a gear 11 meshed with a driving gear 8a provided in the driving source 8, the root of a tooth part 10a is constricted so that the tooth part 10a is cracked.SELECTED DRAWING: Figure 4

    【課題】駆動アームと駆動源とを連繋する伝動手段において、踏板の張出状態で格納方向に過荷重が加わった場合に、伝動手段の特定部分を敢えて破損、欠損させ、踏板を正常に動作させず、故障を認識させる。【解決手段】車両ステップ下部に、回転半径が同一な駆動アームと従動アームの基端を枢着すると共に、駆動アームと従動アームの先端を踏板の底部に枢着し、該踏板を車両ステップ下部の格納位置と車両ステップ下部前方の張出位置との間を同一水平面上で往復移動自在に設け、駆動アームは駆動源8に伝動手段を介して連繋し、該伝動手段において、駆動源8に設けた駆動歯車8aに噛合するラック10又は歯車11に過荷重が作用した時にその歯部10aが歯毀れする様に該歯部10aの根元を括れさせた。【選択図】図4
