<p>PROBLEM TO BE SOLVED: To easily exchange a gas cylinder by rotationally moving gas cylinder fixing means when the gas cylinder is fitted or detached, and moving it to the position on which the fitting or detaching work is not obstructed. SOLUTION: A gas cylinder clamp 11 is constituted of a clamp main body 17 and a lever for fixing a band. The clamp main body 17 is constituted of a fitting member 17a worked by bending similar to a joint part 17b of U-shaped section. The fitting member 17a is formed with two holes 17e, 17e on the extreme end. A plate 14 (a hole 14a formed on the plate 14) is fitted between the two holes 17e, 17e. By such constitution, the gas cylinder clamp 11 can be rotationally moved in the arrow mark (f) directions (upward/downward directions) against the plate 14, and in addition the plate 14 can be rotationally moved in the arrow mark (d) direction (right/left directions) against a supporting member 12 (gas cylinder supports 10a, 10b), namely to the position on which the fitting or detaching work of the gas cylinder is not obstructed.</p> |
