き、締め付け具として軽量でも頑強なものを得ることが
できたという第1の効果が有る。The present invention adopts the above-described embodiment, and has the following effects. Two notches 2 and 2 are formed symmetrically from the opposite two sides of the substantially rectangular tough plate 1 toward the center thereof, and the plate 1 is bent in a substantially U-shape in a plane and a side from between these notches. To make a three-dimensional tightening main body 3 and the notches 2 of the main body 3
The plurality of clamped members 4, 4 inserted between the two are tightly fastened to one notch end side with a male screw 5 screwed into the main body 3 on the other notch end side, thereby clamping the clamped members together. The main body 3 can clamp and hold. Therefore, since the tightening stress applied to the main body 3 is applied to the upper and lower edges of the main body cutouts 2 and 2 in a direction orthogonal to the main body thickness direction, even if the main body 3 becomes thicker, Has the first effect that it can withstand a sufficiently strong tightening stress without being twisted to the left and right, and can obtain a lightweight and robust fastener.
