Thus, the hinge device is combined with the door in the longitudinal direction as a whole to improve the firmness to some extent.

However, the above-described hinge device does not significantly improve the robustness because the fixing member and the rotary member are supported by the single shaft rod. In addition, since the shaft rod is positioned above and below the pipe member of the rotary member, It is difficult to assemble it because it is necessary to fit the lower part to the lower part.

Particularly, in the case where the weight of the door is large, the assembling work of the above-mentioned hinge device has become more inconvenient.
