The dimension of the part along the up-down direction in the partition fin portion 130B4 has substantially the same dimension as the cover fin portion 130A1 of the metal width wood 130A.

  The above-described baseboard 130 is in a state in which the resin-width wood 130B and the metal-width wood 130A are integrated in advance. As a method of integrating, for example, by bonding between the upper surface of the resin cylinder portion 130B1 and the engagement piece portion 130A3, the finding surface of the resin cylinder portion 130B1, the support plate portion 130B3 and the hollow portion 130A2, good. As shown in FIG. 6, the baseboard 130 in which the resin width wood 130B and the metal width wood 130A are integrated is a partition surface 130B4 of the cover width section 130A1 of the metal width wood 130A and the partition surface 130B4 of the resin width wood 130B.

Will be connected below. Therefore, even when the space from the lower frame 122 to the base BB is filled with the mortar MB, the appearance quality of the fixture can be improved without the possibility of the mortar MB being visually recognized from the outside directly.

  Moreover, in this state, the lower portion of the connection portion between the outer frame member 122A and the inner frame member 122B of the lower frame 122 is covered by the resin-spread wood 130B. Therefore, the mortar MB filled in the space from the lower frame 122 to the base BB contacts only the inward frame member 122B in the lower frame 122, and contacts only the resin width wood 130B in the core wood 130.

  Here, the core wood 130 is connected to the lower frame 122 in a state where the metal lumber 130A contacts only the outer frame member 122A of the lower frame 122. In other words, between the outer frame member 122A of the lower frame 122 and the metal width wood 130A of the baseboard 130, and the inner frame member 122B of the lower frame 122 and the mortar MB, the connecting member 122C of the lower frame 122 and the Since the resin width wood 130B intervenes, the metal width wood 130A of the core wood 130 and the inward frame member 122B of the lower frame 122 are not in contact with each other. Therefore, even if a temperature change occurs in the outer frame material 122A of the lower frame 122 and the metal width wood 130A of the baseboard 130 in direct contact with the outside air, the influence is exerted on the inner frame material 122B and the mortar MB of the lower frame 122. There is no fear of it. As a result, even when the outside air temperature is lower than the room temperature, for example, the floor surface of the entrance does not have a problem such as condensation.

  Furthermore, in this fitting, the connecting member 122C of the lower frame 122 is disposed to face the prospective surface of the door 10 to which the aggregate 11 molded of resin is applied. As a result, the lower frame 122 is unlikely to be affected by the outside air temperature on the inward frame member 122B and the mortar MB of the lower frame 122 via the door 10, and the heat insulation can be further improved.

  In addition, when the partition fin portion 130B4 of the resin width wood 130B is brought into contact with the base heat insulating material BD provided on the base BB, the mortar MB is not likely to be affected by the outside air through the base BB, and the heat insulating property is further increased. It is possible to improve. Furthermore, if a member made of a heat insulating material having a thermal conductivity smaller than that of air is disposed in the space 131 between the cover fin portion 130A1 and the partition fin portion 130B4, the heat insulating property can be improved. .

  In the first and second embodiments described above, the fixture in which the door is supported by the frame via the hinge is illustrated, but the present invention is not limited to this.
