Claims

[Scope of utility model registration request]

A pair of mounting plates 1, 4 having cylindrical parts 2, 5 are pivotally supported to be openable and closable by a pivot 7 fitted in the cylindrical parts 2, 5, and end surfaces of both the cylindrical parts 2, 5 that are slidably opposed to each other. is a spirally formed hinge that moves in the axial direction as the mounting plates 1 and 4 open, and one cylindrical part 5 is removably fitted into the cylindrical part main body 50 so that the axial center and an auxiliary cylinder 6 having a through hole 66 into which the pivot shaft 7 is fitted so as to be slidable and rotatable in the axial direction, and a helical surface 63 that comes into sliding contact with the spiral surfaces 33 and 34 of the mating cylinder part 2 on the auxiliary cylinder. . A protrusion 65 is provided in the axial direction on one side of the mounting plate 1, and a groove in which the protrusion fits is provided on the other side.
Two grooves 55 and 57 are provided at a slight distance from one protrusion 35 so that the other mounting plate 4 can be engaged at positions slightly shifted inward and outward. Hinge.
