In a hinge in which the cam holder is made to protrude further and the cam holder head is brought into elastic contact with the cam surface, an inner cam 11 is provided at the center of the cam member 4, and a radius of the inner cam 11 is provided on both sides of the inner cam 11. An outer cam 13 having a radius R larger than 14 and the outer cam surface 15 increases, and the cam presser 5 is held at a height of about 14 mm.
The height H of the protruding head 16 of the cam presser 5 is set to be equal to the height difference S between the outer cam surface 15 and the inner cam surface 14 when the right blade 2 and the right wing 2 are rotated by 5 degrees. When the left blade 1 is opened to 180 degrees, the inner edge 28 of the right blade and the inner edge 26 of the left blade collide to prevent excessive rotation of both blades due to spring pressure; A folding door hinge featuring:
