PROBLEM TO BE SOLVED: To provide a legless chair which has improved transfer performance since a seat of the legless chair and an object (for example, a bed or a wheelchair) can be disposed in a width direction of the seat side by side without a gap since the width of the seat is the maximum width in the legless chair thereby enabling a user of the legless chair to more easily transfer from the seat to the object.SOLUTION: The legless chair 1 includes a leg part 2 installed on a floor surface 4 and a seat 3 which is joined to the leg part 2 and goes up and down by driving force. The width of the seat 3 is the maximum width in the legless chair 1.COPYRIGHT: (C)2008,JPO&INPIT【課題】移乗性を向上できる座椅子を提供すること。【解決手段】床面4に設置される脚部2と、脚部2と連結し、駆動力を受けて昇降する座面3とを備える座椅子1であって、座面3の幅が座椅子1における最大の幅である構成としたこと。【選択図】 図1
