ている。As shown in FIGS. 8 and 9, the downward hooks 23 projecting from both connecting plates 19 of the connecting member 3 fixed to the connecting rod 2 are attached to the side surfaces 16 of the column 1. Are fitted into and locked to the lower edges 17a of the locking holes 17, and the elastic restricting body is held in a state where the edge 21 of the connecting plate 19 and the end face 22 of the connecting rod 2 are in contact with the side surface 16 of the column 1. After the insertion portion 34 of 4b is positioned in the cutout portion 24, the insertion portion 34 is inserted between the upper edge of the downward hook 23 and the upper edge 17b of the locking hole 17 while guiding the insertion portion 34 with the horizontal edge 25. The short pieces 36 are passed through the vertical edges 26 in the cutouts 24 and the long pieces 37 are brought into contact with the surface of the connecting plate 19 by compressing the pieces 33, 33 so as to narrow the opening angle of the legs. By inserting the engaging groove 35 into the vertical edge 26, The part 34 is always biased in a direction to fit into the retaining hole 17 and the detent and is to retaining because the downward hook 23 in the insert 34. Here, the insertion portion 34 is fitted into the locking hole 17, and the engagement groove 35 is
In the state of engagement with the vertical edge 26, the two leg pieces 33 are constantly elastically urged in the expanding direction, and the engaged state is reliably maintained.

ある。According to the first aspect, after the downward hook protruding from the connecting plate vertically extending from the end of the connecting rod is fitted and locked into the vertically long locking hole formed on the side surface of the support column or the like, it is separated. The insertion portion of the elastic regulating body made of a body is laterally opened at the edge of the connecting plate located at the upper end of the hook, and a cutout formed between the upper end of the hook and the upper edge of the locking hole. By inserting and stopping the insertion portion by the detent means provided on the elastic regulating body, the upward movement of the hook can be restricted, and the hook can be prevented from being pulled out and the connecting rod can be connected to the support or the like. Also, since the elastic restricting body is manufactured separately from the connecting rod or the connecting member, the manufacturing process can be omitted, and the cost can be reduced.

る。According to the second aspect, the elastic regulating body has a substantially U-shape in a plan view, which is fitted to the connecting member, and the distal end portions of both spring pieces are stepped inward to form an insertion portion. Since the dowel as a detent means is projected from the outer surface of the insertion part, the insertion part is inserted between the upper edge of the downward hook and the upper edge of the locking hole, and the dowel passes through the locking hole. Then
Since the insertion part is detented, there is no danger that the downward hook may accidentally come off from the locking hole due to vibrations during movement, and when removing the connecting rod from the support, pull the elastic regulating body to remove the insertion part. It can be easily done by pulling out from the locking hole, and even if the connecting rod is not connected to the support,
By fitting the elastic restrictor outside the connecting member and fitting both insertion portions into the cutouts, the elastic restrictor does not come off the connecting member, and thus the loss of the elastic restrictor can be prevented.

るのである。According to the third aspect of the present invention, the insertion portion is bent outward at the tip of one of the legs in a substantially V-shape in plan view as the elastic regulating member, and the insertion portion is formed at the tip of the other leg. Since an engagement groove is formed as a detent means in the opposite direction, the insertion portion of the elastic regulating body is fitted between the upper edge of the downward hook and the upper edge of the locking hole, and the engagement groove is formed in the notch. It is engaged with the vertical edge and is always elastically urged in the expanding direction by both legs, so that the mounting state of the elastic regulating body is extremely stable,
There is no danger that the downward hook may come off from the locking hole unexpectedly due to vibration or the like at the time of movement, and the work of attaching and detaching the elastic regulating body can be easily performed with the fingers from the front side of the connecting plate of the connecting member.
