<P>PROBLEM TO BE SOLVED: To prevent rear part legs from colliding with each other to be scratched when arranged back to back when each leg strut is an aluminum product. <P>SOLUTION: An leg 2 supporting a top plate has a gate shape having front and back leg struts 3 and an upper frame 4 connecting them. The leg strut 3 and the upper frame 4 are connected by an L-shaped joint member 41 having a horizontal part and a vertical part, and the joint member 41 has a flange 44 interposed between junction faces of the leg strut 3 and the upper frame 4. An upper end part of a rear face plate 3a configuring the rear part leg strut 3 is formed with a cut-opened part having an upward opening, the cut-opened part is closed from above by the flange 44 of the joint member 41 to form a square engagement hole 72, and a resinous buffer material 73 is fitted and mounted in the engagement hole 72. By the presence of the buffer material 73, it is prevented that both the rear part legs 3 collide with each other to prevent the scratching. <P>COPYRIGHT: (C)2013,JPO&INPIT |
