To provide a ladder supporting device with improved stability and safety to prevent a ladder from inclining too large wherever a worker steps up when the worker climbs the ladder leaned against a column-like body.SOLUTION: Holding members guided at the outer periphery thereof by a guide as a main pressure applying member to a column-like body which is fixedly installed to the ladder from both of width directions (right/left) are advanced in opposite directions through accumulating resilient strength and held.SELECTED DRAWING: Figure 1
【課題】柱状体に凭せ掛けた梯子に作業者が昇った時、作業者の立ち位置に依っても梯子の大幅な傾きを防止し、その安定性、安全性を向上した梯子支持装置の提供。【解決手段】柱状体に対し、主加圧力として梯子の幅（左右）方向から該梯子に固定して設置されたガイドで外周を案内された把持子を、弾力を重畳した力で対向状に前進させて把持する。【選択図】図１
