To improve water pressure resistant performance of a door frame formed by multiple members.SOLUTION: A sill 3 is formed by a first member 33 and a second member 34. A first surface of a recess groove 322 of the sill 3 comprises an indoor side part of a first side 330 of the first member 33, a second surface of the recess groove 322 comprises a second side 341 of the second member 34, a bottom surface of the recess groove 322 is formed by a third side 342 of the second member 34, a second side 331 of the first member 33 is welded in an abutted state onto a back surface of the third side 342 of the second member 34 forming the bottom surface of the recess groove 322 and a bottom surface part of the recess groove 322 comprises an overlapping part obtained by welding the second side 331 of the first member 33 and the third side 342 of the second member 34 in the abutted state.SELECTED DRAWING: Figure 4 【課題】複数部材から形成されたドア枠の耐水圧性能を向上させる。【解決手段】下枠３は第１部材３３と第２部材３４とから形成されている。下枠３の凹溝３２２の第１面は、第１部材３３の第１辺３３０の屋内側部位からなり、凹溝３２２の第２面は、第２部材３４の第２辺３４１からなり、凹溝３２２の底面は、第２部材３４の第３辺３４２から形成され、凹溝３２２の底面を形成する第２部材３４の第３辺３４２の背面に第１部材３３の第２辺３３１が当接した状態で溶接されており、凹溝３２２の底面部は、第１部材３３の第２辺３３１と第２部材３４の第３辺３４２を当接状態で溶接してなる重なり部からなる。【選択図】図４
