To prevent a wire from separating from an upper sheave below a sheave wound portion.SOLUTION: A lifting/lowering apparatus comprises: a base stand 3; a base support post 4; an upper support post 6; a load receiving tool 7 supported by the upper support post 6 so as to be vertically movable; and a wire drive mechanism 8 extending a wire W from the base support post 4 to the upper support post 6 and pulling the wire W toward the base support post 4, thereby lifting the load receiving tool 7 relative to the upper support post 6 and lifting the upper support post 6 relative to the base support post 4. The wire W connects its leading end to an upper part of the upper support post 6 or to the load receiving tool 7, and an upper part of the upper support post 6 has an upper sheave 26 around which an intermediate part of the wire W is wound. The upper part of the upper support post 6 is provided with a wire guide 10 that prevents the wire W from separating from the upper sheave 26 below a sheave wound portion of the wire W.SELECTED DRAWING: Figure 1

    【課題】 シーブ巻き掛け部分の下方でワイヤが上シーブから離間するのを防止できるようにする。【解決手段】 基礎台3と、基礎支柱4と、上段支柱6と、この上段支柱6に上下移動可能に支持された荷受具7と、基礎支柱4から上段支柱6までワイヤWを延設して、このワイヤWを基礎支柱4側に引っ張ることにより、荷受具7を上段支柱6に対して上昇させ、上段支柱6を基礎支柱4に対して上昇させるワイヤ駆動機構8とを備えている。前記ワイヤWは先端を上段支柱6の上部又は荷受具7に連結しており、上段支柱6の上部にはワイヤWの中途部を巻き掛ける上シーブ26を有している。前記上段支柱6の上部には、ワイヤWのシーブ巻き掛け部分の下方でワイヤWが上シーブ26から離間するのを防止するワイヤガイド10を設けている。【選択図】図1
