To provide a lifting device with a fall-preventing mechanism, which is capable of ensuring prevention of falling of a lifting base safely.SOLUTION: A lifting device 10 has a pin-type stopper 30 provided on the outer surface of a support pillar 14 so as to make visible a pin 32 and an operation part 34 through which the pin 32 is inserted/pulled out. A recess 27 that serves as a hook is provided to the surface of a lifting member 26 opposed to the pin-type stopper 30. The pin 32 fed out through the operation part 34 of the pin-type stopper 30 penetrates the support pillar 14 to fit in the recess 27. The pin 32 is engaged with the lower surface 27a of the recess 27 when the lifting member 26 falls, and thus prevention of falling of a lifting base 28 is ensured without affecting tilting of the lifting base 28.SELECTED DRAWING: Figure 1

    【課題】安全・確実に昇降ベースの落下を防止することができる落下防止機構付昇降装置を提供すること。【解決手段】昇降装置10は、支柱14の外面上に、ピン32とピン32を出入させる作動部34を具えるピン型ストッパー30が設けられている。昇降部材26のピン型ストッパー30に対向する面には、掛止部である凹部27が設けられている。ピン型ストッパー30の作動部34によって送出されたピン32は、支柱14を貫通して、凹部27に嵌合する。昇降部材26が降下したとき、ピン32は、凹部27の下方面27aに掛合するという構成であるため、昇降ベース28の傾きに影響を殆ど受けることなく、昇降ベース28の落下を確実に防止することができる。【選択図】図1
