PROBLEM TO BE SOLVED: To always keep constant the opening/closing of lid part of a portable information terminal in simple configuration by providing the hinge part of an interposing means between the lid part and a main body and engaging them by a movable shaft energized through an elastic member to the hinge part. SOLUTION: A hinge part 30 of the interposing means is provided between the lid part and the main body, they are engaged by movable shafts 31 and 33 energized through elastic members 31a and 33a to that hinge part 30 and with that energizing force, the stable opening/closing load of the lid part is supplied. In this case, a movable limiting recessed part provided at the hinge part 30 limits the move of a limit part provided on the movable shaft 31 so that this limit part can be moved only inside this recessed part. Then, the slope of the movable shaft 31 is abutted with the slope of a movable bearing part and that abutted state becomes friction in the case of rotation. Namely, the friction abutting these respective slopes is determined at prescribed force by the energization of the elastic member 31a. Therefore, since the lid part is always energized in fixed direction by the elastic member 31a, the fixed load is applied on the opening/closing rotation of the lid part. |
