When the fixing seat 40 is integrally formed of a synthetic resin as in this embodiment, not only is it easy to manufacture and the overall cost can be reduced, but also if the portion exposed to the outside in the mounted state is made of metal. When the door attachment frame 2 is made of a wooden material so as not to give a different quality, it is possible to suppress poor appearance of the texture. Further, a painting step is not required as compared with the case of metal, and this also contributes to a reduction in manufacturing cost.

Further, by making the middle plate 42 have a substantially U-shaped cross section, the deformation in the adjustment is not caused by the integrated structure with the fixed seat 40 made of synthetic resin having low rigidity, but by the shape of the metal middle plate 42. Can be expressed only from the above, whereby reliability in long-term use can be ensured. In addition, by adopting a configuration in which the adjusting screw 30 is screwed into a nut 48 provided in a state of being embedded in the fixed seat 40, it is possible to avoid a decrease in rigidity in a main part.

[0032]

According to the hinges of the first and second aspects, there is no need to loosen or tighten the fixing screw with respect to the fixing seat, and simply operate the adjusting screw from the outer surface of the blade plate at the time of mounting, irrespective of after mounting. Since the desired adjustment amount can be obtained directly by simply performing the adjustment, the adjustment operation can be performed easily and quickly, and the handling and the usability can be improved. In particular, the distance between the intermediate plate on the side close to the shaft cylinder and the fixed seat was adjusted, and in synchronization with this, the attachment piece could be bent and deformed on the side away from the shaft cylinder. Therefore, the left-right adjustment of the door can be made large and reliable.

According to the hinge of the third aspect, the fixing of the middle plate to the fixed seat is easy, and the deformation in the adjustment can be expressed irrespective of the material of the fixed seat. Can be avoided. In particular, the gap on the side close to the shaft cylinder at the free end of the surface portion of the U-shaped middle plate was adjusted, and at that time, the side surface on the side away from the shaft cylinder could be deformed by the opening. Therefore, the left-right adjustment of the door can be made large and reliable.
