<P>PROBLEM TO BE SOLVED: To make a damper effective securely to prevent occurrence of shock sound when closing even when a self-weight drop angle (height) is changed due to permanent set in fatigue of a spring and prevent marked change of sense of operation before and after damper operation. <P>SOLUTION: In this hinge device provided with a first mounting member and a second mounting member turning relatively, a buffer member (spring) 16, and a shock reducing means (damper) 12, the shock reducing means 12 operates before starting to drop (close) without using external force by self-weight (weight) of an object to be opened and closed when rotation moment of the object and closed attached to the first mounting member and rotation moment by the buffer member 16 are in an imbalance condition. <P>COPYRIGHT: (C)2007,JPO&INPIT |
