PURPOSE: A hinge device is provided to enable a smooth and correct relative motion between a member having a cam follower and a member having a cam surface. And the hinge device enables the reduction of the size, according to the miniaturization of a wireless phone. CONSTITUTION: One end of a hinge device is partly closed, and the other end of the hinge device is opened. A housing(24), the first member(26), the second member(28) and an elastic member(30) are arranged near the opened end of the hinge device. The metal housing(24) has a stopping protuberance(48) capable of being curbed. And the first member(26), the second member(28) and the elastic member(30) are sequentially connected with the housing(28). The second member(28) has a cam(64). The cam(64) has a peak and two valleys divided by the peak, and has a continuous form to connect the peak and valleys. A cam follower formed in the first member(26) is interacted with the cam(64). The elastic member(30) inclines the second member(28) to the first member(26). |
