To provide a support tool capable of steplessly repositioning a support arm portion provided on the peripheral side surface of a telescopic device.SOLUTION: A support tool 1 comprises: a telescopic device 2 consisting of a screw jack structure, which includes a multi-cylindrical body 3, and a power transmission shaft 5 which is located on the central axis of the multi-cylindrical body 3 and stretches and retracts individual cylinders 3a-3c that make up the multi-cylindrical body 3 while preventing them from rotating; and a support arm 13 that is slidably provided on the outer surface of the cylinder 3c and directly or indirectly supports an object to be supported. The cylinder 3c has a non-contained area B that is not contained in a hollow portion of the outermost cylinder 3a. The non-contained area B includes a screw portion 22 formed on the peripheral side surface thereof, a position adjusting portion 17 screwed on the screw portion 22, and an annular portion 16 that is provided around the outer surface of the non-contained area B and directly or indirectly supports the support arm 13 by restricting the slide in the non-contained area B by the position adjusting portion 17.SELECTED DRAWING: Figure 2

    【課題】、伸縮装置がその周側面上に支持用腕部を備え、この支持用腕部を無段階で位置変更することができる支持具を提供する。【解決手段】多重筒体3と、この多重筒体3の中心軸上に配されて多重筒体3を構成する個々の筒体3a〜3cの供回りを防止しながら伸縮させる動力伝達軸5と、を備えたスクリュージャッキ構造からなる伸縮装置2と、筒体3cの外側面上にスライド可能に設けられ、支持対象物を直接又は間接的に支持する支持用腕部13と、を備え、筒体3cは、最外の筒体3aの中空部内に収容されない非収容領域Bを備えており、この非収容領域Bは、その周側面上に形成されるネジ部22と、このネジ部22に螺設される位置調整部17と、非収容領域Bの外側面上に周設されて、位置調整部17により非収容領域Bにおけるスライドが規制され、支持用腕部13を直接又は間接的に支える環状部16と、を備えている支持具1による。【選択図】図2
