PROBLEM TO BE SOLVED: To enable applying this machine into a chair, a table or a sitting stand or the like by permitting the horizontal direction angle of a top plate arranged at the upper end of an elevating/lowering member in a horizontal direction to be adjustment possible. SOLUTION: An angle adjusting mechanism is disposed at the upper end of a driving rod 22 constituting the elevating/lowering member 21 and the top plate 33 is mounted with it. The mechanism is constituted of a connecting member 35, a connecting pipe 36, a gas spring 37, a top plate connecting plate 38, a bar member 39 and an adjustment handle 40. The top plate 22 is vertically moved in accordance with the vertical motion of the driving rod 22 to adjust the horizontal direction angle. For example, the upward pulling of the adjustment handle 40 makes the bar member 39 move forward, the bottom surface of a press tool 46 pushes a lock pin 45 and the gas spring 37 is made to be extension/contraction possible. Thus, when force to the top plate 33 is zero, a shaft 48 is extended and the top plate 33 and the top plate connecting plate 38 are inclined in an angle of elevation with a second pin member 42 as a fulcrum. Then the machine is fixed when the adjustment handle 40 is separated. Thus, the application of this machine into the chair or the table or the like is attained. |
