- the elastic member is assembled to the guide plate in a state where the first slide member and the second slide member are connected by the connecting member.
- the frictional resistance applied to the second slide member is small, the effect of assisting the rotation of the rotation side casing by the elastic member is sufficiently exhibited. Further, since the elastic member can be unit-assembled with the guide plate, the mobile terminal can be easily assembled.
- the elastic member has one end rotatably connected to the one side surface at the upper end of the guide plate, and the other end passing through the spring opening opened along the rail portion.
- a torsion coil spring rotatably connected to the side surface.
- the other end of the torsion coil spring does not directly bias the second slide member (rotation side housing) but biases it through the link member, so use the lever principle.

- the rotation support mechanism can be accommodated in the movement opening of the rotation side casing when the rotation side casing is in the vertically long state or the horizontally long state, so that the rotation support mechanism does not protrude. Is good.
- the rotation support mechanism since the rotation support mechanism always moves in the movement opening, the rotation-side casing only wobbles within the clearance with the movement opening while the rotation-side casing is rotating, and an unexpected impact is applied to the rotation-side casing.
- the load is also transmitted to the peripheral edge of the opening for movement, the load is prevented from concentrating only on the rotation support mechanism, and the rotation support mechanism is hardly damaged.
- the thickness of the rotation support mechanism is suppressed, the width of the movement opening is reduced, and the thickness of the rotation side housing is also suppressed.
- the rotation support mechanism that moves in the movement opening is slid while tilting in the thickness direction of the rotation-side casing, and in the horizontally long state, the movement opening at the lower corner portion of the rotation-side casing is A lower shielding member that is closed and fully accommodated in the rotation-side casing in the vertically long state;

Since the hinge shaft is directly assembled, the backlash is less likely to occur compared to the case where the hinge shaft configured as a separate part is attached to the housing that covers the support mechanism as in the prior art. For this reason, backlash between the rotation-side casing and the fixed-side casing is suppressed. Further, since the guide hole for the second slide member is not necessary as compared with the conventional case, the upper end of the guide plate is lowered. For this reason, the upper side of the rotation-side casing in the horizontally long state can be lowered, and as a result, the gap between the hinge portion and the lower side of the rotation-side casing in the horizontally long state is reduced, and the appearance is good.
