Abstract
A hinge device for a portable terminal including a first housing, a second housing foldably coupled to the first housing is disclosed. The hinge device causes the first housing and the second housing to be rotatably coupled in such a manner that both housings are either rotated away from each other, or both housings are rotated close to each other. The hinge device includes a hinge shaft fixed to one of the first housing or the second housing. The hinge shaft has a first cam surface on one surface. A hinge cam is movably coupled on the other housing of the first housing and the second housing and has a second cam surface opposite to the first cam surface. An elastic member provides an elastic force in such a way as to cause the second cam surface to contact the first cam surface. The first cam surface has a first peak portion, and the second cam surface has a stopper groove. The first peak portion is engaged with the stopper groove when the second housing is opened with respect to the first housing between about 90° and 115°.
