PROBLEM TO BE SOLVED: To connect both first and second plates together as wall as to make them so as not to be easily slipped off even in the case where thickness in the first plate is larger than the counterpart by raising up an antislip piece bendably by hand after inserting a leg of the first plate into a hole of the second plate. SOLUTION: A U-shaped notch 15 is applied on a first leg 13 installed in a first plate 11 by means of laser beam machining or the like. This first leg 13 is inserted into a hole 14 of a second plate 12. Next, a tool suitable to add man power such as a driver is inserted into a tool hole 17, stirring up there, and thereby an antislip piece 16 is bendably raised up, insomuch that its tip is made so as to be floated as far as a degree of thickness or so of the first plate 11. The tip of the antislip piece 16 bendably raised up contacts in parallel with the second plate 12 at an edge of the hole 14, having the first plate 11 clamped tight to the second plate 12. A position of the tip of the antislip piece 16 is pushed frontward by being effective of plate thickness, and since size becomes somewhat smaller than the thickness of the second plate, a proper clearance is produced in space between the tip and the second plate 12, so that there is no fear of any possible lost motion at all. |
