To make it possible that a cart stopper partially bends and becomes hard to deform in such a manner that both of a hanger spring for energizing the cart stopper to a projection position and a hinge connection part for so connecting the cart stopper as to rotate around a rotation axis are provided at a same place of a stopper accommodation recess provided in a load-receiving platform, and energization force of the hanger spring is so made as to be directly act on the hinge connection part.SOLUTION: A hinge connection part H is located at a position of a hanger spring 28, and even if a force of a wheel of a cart as a load is applied to a part where the hanger spring 28 is positioned, a cart stopper 15 can be reinforced by the hinge connection part H, and the cart stopper 15 is so made as to be hard to deform.SELECTED DRAWING: Figure 3 【課題】荷受台に設けたストッパ収容凹部の同じ個所に、カートストッパを突出位置に付勢するハンガスプリングおよびカートストッパを回動軸回りに回動するように連結するヒンジ連結部とを併設し、ハンガスプリングの付勢力が、ヒンジ連結部に直接及ぶようにし、ストッパが部分的に撓んで変形しにくくする。【解決手段】ハンガスプリング２８の位置にヒンジ連結部Ｈを配置して、ハンガスプリング２８が位置する部分に、積荷である、カートの車輪の力が加わってもヒンジ連結部Ｈでカートストッパ１５を補強することができ、カートストッパ１５を変形しにくくする。【選択図】図３
