たバランス型蝶番装置。 A support member having an elongated hole formed in a frame surface, a rotating member pivotally attached to the support member by a pivot, and a cam receiving member provided on the supporting member, wherein either of the pivot shaft and the cam receiving member is provided. One of the rotating members is loosely inserted into the elongated hole, and the tip of the rotary member is made in a cam part and brought into contact with the cam receiving member, and the pivot and the cam receiving member are loosely inserted into the elongated hole. One end of a coil spring is connected to the other end of the coil spring, and the other end of the coil spring is locked to a spring force adjustment member, and the cam receiving member and the cam are connected to each other by the force of the coil spring using this adjustment member as a fulcrum. The spring force adjusting member is configured to be movable in the axial direction of the coil spring and fixed at the moving position, and the fulcrum of the coil spring is moved by the spring force adjusting member. A balanced hinge device configured to increase or decrease the rotational torque generated by the cam receiving member and the cam portion.
