To be equipped with a hinge device with which it is possible to heighten stability in the case when use is made between two housings in a plurality of modes corresponding to a pivoting angle.SOLUTION: A portable information apparatus comprises a first housing, a second housing adjacent to the first housing, and a hinge device for relatively pivotably connecting the first housing and the second housing. The hinge device includes a first torque generation unit for generating a rotary torque to the relative rotation of two by slide resistance between a first base plate and a first link plate, and a second torque generation unit for generating a rotary torque to the relative rotation of two by slide resistance between a second base plate and a second link plate. The hinge device is such that the second torque when the pivoting angle of the first housing and the second housing lies between a 120-degree attitude and a 140-degree attitude is larger than the first torque when the pivoting angle lies between a 0-degree attitude and a 20-degree attitude, and further a third torque in a 180-degree attitude is larger than the second torque.SELECTED DRAWING: Figure 9 【課題】２つの筐体間を回動角度に応じた複数のモードで使用する際の安定性を高めることができるヒンジ装置を備える。【解決手段】携帯用情報機器は、第１筐体と、前記第１筐体と隣接する第２筐体と、前記第１筐体と前記第２筐体とを相対的に回動可能に連結するヒンジ装置と、を備える。ヒンジ装置は、第１ベースプレートと第１リンクプレートとの間の摺動抵抗により、両者の相対回転に回転トルクを発生する第１トルク発生部と、第２ベースプレートと第２リンクプレートとの間の摺動抵抗により、両者の相対回転に回転トルクを発生する第２トルク発生部と、を有する。ヒンジ装置は、第１筐体と第２筐体との回動角度が０度姿勢と２０度姿勢との間にある場合の第１のトルクよりも、１２０度姿勢と１４０度姿勢との間にある場合の第２のトルクが大きく、さらに、第２のトルクよりも１８０度姿勢での第３のトルクの方が大きい。【選択図】図９
