At least one of them (for example, a long vertical crosspiece) can be applied to a plurality of door panels 1 having different door height dimensions H1, and the long members can be shared. In addition, it is possible to improve the procurement of long members constituting the door panel 1 having a relatively large door height dimension H1, and such a door panel 1 can be easily realized. Further, the structure can be simplified and the length of each of the vertical crosspieces 14 and 15 constituting the vertical frame portions 13 and 13 can be simplified as compared with the case where each of the vertical crosspieces 14 and 15 is provided with three or more vertical crosspieces. Rigidity can be ensured by the vertical crosspieces 14a and 15a.
Further, the first vertical rail portion 14 has a configuration in which a long vertical rail member 14a on one side in the door height direction and a short vertical rail member 14b on the other side in the door height direction are joined, and the second vertical rail portion 15 is formed on the other side in the door height direction.

With such a configuration, the joint positions 4 and 5 of the vertical crosspieces 14 and 15 are different from each other in the door height direction. For example, the joint positions 4 and 5 are at the same position (same height position) in the door height direction. ), It is possible to suppress the decrease in rigidity.

In the present embodiment, both the vertical frame portions 13 and 13 on both sides are joined by joining the two vertical rail portions 14 and 15 formed of a wood-based material so as to be adjacent to each other in the door width direction. With such a configuration, the rigidity of the vertical frame portions 13 and 13 at both ends in the door width direction of the door panel 1 can be effectively improved, and warpage, deformation and the like can be suppressed.
