PROBLEM TO BE SOLVED: To provide a spring type tension balancer drawer device relatively small in size and low in weight, which can easily handle a device and carry out the device loading/pulling out operation by only one high-place worker.SOLUTION: A drawer device 1 is provided with: a mounting member 2 that is detachably hooked to an outer cylinder; a pair of screw jacks 3 that is detachably supported by the mounting member 2 and that projects a screw shaft 4 having an axis directed in parallel with the axis of an outer cylinder 52 toward the tip of the outer cylinder 52; a connection member 5 that detachably couples the screw shaft 4 to the tip side of an inner cylinder 53; and a drive shaft 6 that simultaneously drives the screw jacks 3. The screw jacks 3 are provided with drive gears 32 opposed to each other so as to arrange spline holes 32a on the same axis. The drive shaft 6 is provided with a driving operation unit on one end side, and comprises a spline shaft freely inserted into/pulled out from the spline hole 32a of each of the drive gears 32.SELECTED DRAWING: Figure 3
【課題】比較的、小型軽量で、取り扱いが容易であり、1人の高所作業者だけで装置の装着と引き出し操作を行えるばね式張力バランサの引き出し装置を提供する。【解決手段】引き出し装置1は、外筒に離脱可能に懸架される取り付け部材2と、この取り付け部材2に離脱可能に支持され軸線を外筒52の軸線と平行に向けたねじ軸4を外筒52の先端方向へ突出させる一対のスクリュージャッキ3と、ねじ軸4を内筒53の先端側に離脱可能に結合する連結部材5と、一対のスクリュージャッキ3を同時に駆動するための駆動軸6とを具備する。スクリュージャッキ3は、互いのスプライン孔32aを同一軸線上に配置させるように対向した駆動歯車32をそれぞれ具備する。駆動軸6は、一端側に駆動操作部を具備し、駆動歯車32のスプライン孔32aに抜き差し自在のスプライン軸からなる。【選択図】図3
