To improve detection sensitivity of a posture of a caster stopper and secure a distance between the caster stopper and a proximity sensor, and protect the proximity sensor.SOLUTION: A load receiving platform lifting device for assisting loading/unloading of a cargo relative to a loading platform of a vehicle includes: a load receiving platform which is elevated/lowered between a height of a floor surface of the loading platform and a grounding height; a caster stopper which is configured to change its posture between an erected posture projecting from a load receiving surface of the load receiving platform, and a fallen posture constituting a part of the load receiving surface; a proximity sensor which is provided on one of the caster stopper and the load receiving platform, and detects a posture of the caster stopper; and a target which is a component to be detected by the proximity sensor and is provided on the other of the caster stopper and the load receiving platform, wherein the target is formed of a material different from the other caster stopper or load receiving platform.SELECTED DRAWING: Figure 6
【課題】キャスタストッパの姿勢の検知感度を向上させてキャスタストッパと近接センサとの距離を確保し、ひいては近接センサを保護する。【解決手段】車両の荷台に対する荷物の積み降ろしを支援する荷受台昇降装置において、前記荷台の床面の高さと接地する高さとの間を昇降する荷受台と、前記荷受台の荷受面から突出した起立姿勢、及び前記荷受面の一部を構成する倒伏姿勢に姿勢変化可能に構成されたキャスタストッパと、前記キャスタストッパ及び前記荷受台の一方に設けられ、前記キャスタストッパの姿勢を検知する近接センサと、前記近接センサによる検知対象部品であり、前記キャスタストッパ及び前記荷受台の他方に設けられたターゲットを備え、前記ターゲットが、前記他方である前記キャスタストッパ又は前記荷受台と異なる材料で形成されている荷受台昇降装置を提供する。【選択図】図6
