To provide a load platform lifting/lowering device in which a cart stopper is hinged and coupled to a load platform in a derricking manner, and the cart stopper is energized by a hanger spring to a projection position, and further, in which deformation of the cart stopper can be suppressed by reinforcing the cart stopper using a hinge coupling part pivotally supporting the cart stopper on the load platform, and also in which a degree of freedom in design is enhanced by restricting interference between the hanger spring and other components in the periphery of the hinge coupling part.SOLUTION: A hanger spring 28 is formed into a U-shape including a pair of side piece parts 28a, 28b aligned at an interval and an intermediate bent part 28c connecting between both side piece parts. One side piece part 28a is adjacent to a side surface 20s on one side in a left/right direction, of any one hinge member 20 of a hinge coupling part H, whereas the other side piece part 28b projects outward from a side surface 21s on the other side in the left/right direction, of the other hinge member 21 by passing a rear side of any other hinge member 21. Further, the other side piece part has a regulating part 28bs which is engageable with the side surface 21s on the other side, on a projection end part thereof.SELECTED DRAWING: Figure 6

    【課題】荷受台にカートストッパを起伏可能にヒンジ連結し、カートストッパをハンガスプリングで突出位置に付勢する荷受台昇降装置において、カートストッパを荷受台に軸支するヒンジ連結部でカートストッパを補強することでカートストッパの変形を抑制可能とし、併せて、ハンガスプリングとヒンジ連結部周辺の他の部品とを干渉しにくくして設計自由度を高める。【解決手段】ハンガスプリング28は、間隔をおいて並ぶ一対の側片部28a,28bとその両側片部間を接続する中間曲がり部28cとを有してU字状に形成され、一方の側片部28aがヒンジ連結部Hの何れか一方のヒンジ部材20の、左右方向一方側の側面20sに隣接し、また他方の側片部28bは、何れか他方のヒンジ部材21の裏側を通って他方のヒンジ部材21の、左右方向他方側の側面21sより外方に張出し、且つその張出端部に該他方側の側面21sと係合可能な規制部28bsを有する。【選択図】 図6
