PROBLEM TO BE SOLVED: To prevent the deterioration of an electric characteristic by preventing the movement of a hinge part for connecting an upper panel and a lower panel so as to freely open and close in the case of an electronic equipment or the like. SOLUTION: A hinge boss (A) 3 to which a ring-shaped plate spring 6 is interfit and fixed inside a cylindrical hinge part 2a of a lower panel 2 is fixed through a coil spring 5 and a hinge axial screw 7 to an upper panel 1 side so as to be slidable in an arrow A direction. The outer peripheral part of the hinge boss (A) 3 is provided with a groove 3a for sliding. At the time of opening and closing the upper panel 1, the hinge boss (A) 3 and a hinge boss (B) 4 at the upper panel 1 side are mutually projection-recession interfit, and stopped at a prescribed angle, and simultaneously a tongue piece 6a at the tope end of the ring-shaped plate spring 6 is pressured and brought into contact with a side wall 2c of a projecting part 2b as a guide rail so that a clearance between the projecting part 2b and the groove 3a can be suppressed. Thus, movement at the time of opening the upper panel 1 can be prevented. |
