価を低下できる等の諸効果をもつ。 The present invention has the configuration illustrated in the above embodiment, and when there is a slight eccentricity between the axes a and a, the boss pipe 1 and the metal flanges 2 rotate while remaining eccentric, but the flexible sewn flange 5, 5, the mutually contacting joint surfaces 7,
The eccentricity is absorbed by the strain at 7, resulting in a so-called flexible-acting axial connection. Therefore, the connecting bolt 11 that connects and fixes both flexible seizing flanges 5, 5 is loosely inserted into each connecting hole 8, 8, but is almost tightly inserted into the through hole 10 of the ring-shaped washer 9. The ring-shaped washer 9 not only passes through the connecting holes 8, but also restricts the insertion position of the plurality of connecting bolts 11 into the connecting holes 8, 8, so even if the flexible seizing flanges 5, 5 are slightly eccentric from each other, In addition, the ring-shaped washers 9, 9 maintain tightness around the entire circumference of the flexible baked flanges 5, 5 near the outer periphery of each of the joint surfaces 7, 7. Avoid friction as much as possible. Further, a part of the material of the flexible sewn flange 5 filled in the connecting groove 3 of the metal flange 2 firmly maintains the integral connection of the metal flange 2 and the flexible sewn flange 5 in the rotational direction. Even if the joint surfaces 7, 7 of the flexible seizing flanges 5, 5 are slightly distorted due to a slight eccentricity of the axes a, a, the continuous joint groove 3 is expanded inside the opening 4, so that There was no failure such as escape or breakage of the rubber material filled in the continuous connecting groove 3, and furthermore, the circular protrusions 6, 6 protruding in the opposite direction to the connecting surfaces 7, 7 on the outer periphery of the flexible flanges 5, 5, The ring-shaped washers 9, 9 are fitted into the guide and the flexible flanges 5, 5 are held in position, and a highly durable power transmission function can be maintained. Therefore, the present invention has the simplest structure of the sewn flange type, and the shaft connection can be easily performed by using the ring-shaped washers 9, 9 and the connecting bolt 11, so that the number of work steps can be reduced. Furthermore, the number of parts can be reduced, and the mold for forming the flexible baked flange can be simplified, resulting in various effects such as lowering the unit production cost.
