<p>Disclosed herein is a hinge device for connecting first and second units which can be relatively rotated about a rotational axis and folded or unfolded with respect to each other. The hinge device of the present invention comprises a first connecting member connected with the first unit to be rotated together with the first unit and to be linearly moved along the rotational axis; a second connecting member connected with the second unit to be rotated together with the second unit; an elastic member for pushing the first connecting member toward the second connecting member to bring the first and second members into contact with each other; and a coupling member for coupling the first and second connecting members and the elastic member with one another, wherein one of the first and second connecting members includes a cam surface and the other includes a cam follower interacting with the cam surface; and the first connecting member includes an outer wall surface which has a circular-arc curved portion extending 180 degrees or more in a circumferential direction about the rotational axis, and first and second flat portions extending from both circumferential ends of the curved portion, respectively.</p> |
