PROBLEM TO BE SOLVED: To provide an X-ray supporting device capable of easily fixing and releasing a supporting arm. An X-ray support device 80 fixes and releases a support arm 24 by a lock mechanism of a gas spring 40 by an operation unit 30 provided on the operator's hand side. As a result, the alignment work and the fixing work, that is, the release of the support arm 24, the alignment of the X-ray imaging apparatus 1 by the rotation of the support arm 24, and the fixing of the support arm 24 at that position can be performed by a series of operations. It can be done quickly and smoothly. In particular, in the configuration in which the operation section 30 is provided on the support arm 24, by appropriately grasping the operation section 30 of the support arm 24, the above-described alignment work and fixing work can be performed extremely smoothly without releasing the hand from the support arm 24. Can be done. [Selection diagram] Figure 1【課題】支持アームの固定と解除とを簡単に行う事が可能なＸ線支持装置を提供する。【解決手段】このＸ線支持装置８０は、ガススプリング４０のロック機構による支持アーム２４の固定と解除とを操作者の手元側に設けられた操作部３０によって行う。これにより、位置合わせ作業と固定作業、即ち、支持アーム２４の固定解除、支持アーム２４の回動によるＸ線撮影装置１の位置合わせ、その位置での支持アーム２４の固定、を一連の動作で迅速かつスムーズに行うことができる。特に、操作部３０を支持アーム２４に設けた構成では、支持アーム２４の操作部３０を適宜握持することで上記の位置合わせ作業と固定作業とを支持アーム２４から手を離さずに極めてスムーズに行うことができる。【選択図】図１
