<P>PROBLEM TO BE SOLVED: To provide a lifting device that vertically slidably supports, along a rack, a slide arm for supporting a top plate or the like and fixedly holds it at an arbitrary height position steplessly. <P>SOLUTION: In the lifting device for vertically slidably supporting a slide arm 12 along a rack and for fixedly holding it at an arbitrary height position, the rack has a vertically long flange part 11c projecting to a slide arm 12 side, the slide arm 12 has a holding plate 21, which faces one side of the flange part 11c and is fixedly installed on the slide arm 12, and a locking member 23, which faces the other side of the flange part 11c and is slidably installed on the slide arm, and when the slide of the slide arm 12 is performed downward, the locking member 23 approaches the holding plate 21 accompanying the slide, thereby, the flange part 11c is held between the holding plate 21 and the locking member 23 to be fixedly held, and when the slide of the slide arm 12 is performed upward, the locking member 23 is separated from the holding plate 21 accompanying the slide, thereby, the state of being held therebetween is released. <P>COPYRIGHT: (C)2012,JPO&INPIT |
