To provide, in a portable terminal such as a cellular phone, especially of a foldable type, a hinge for portable terminal that not only has both functions of allowing a second casing having a display portion to turn in a horizontal direction relative to a first casing having a keyboard portion and of allowing the second casing to open/close relative to the first casing, but also is capable of preventing external leakage of a lubricating oil and is formed to be as compact as possible so that a mounting space can be saved. The hinge for portable terminal is a hinge coupling a first casing having a keyboard portion and a second casing having a display portion to each other, including: a rotary hinge part to which the first casing is coupled to be turnable relative to the second casing; and an opening/closing hinge part to which the second casing is coupled to be openable/closable relative to the first casing, wherein: the rotary hinge part has a fixed member attached to the first casing and a rotary member attached to the fixed member with a turn thereof being controlled via a first cam mechanism; and the opening/closing hinge part is provided in the rotary member and has an opening/closing member which is rotatably mounted with a rotation thereof being controlled to be in a perpendicular direction to a direction of the turn of the rotary hinge part via a second cam mechanism and to which an end portion of the second casing is coupled. |
