PROBLEM TO BE SOLVED: To provide a shape joining structure capable of making cut-off performance proper even when an end surface of one shape is displaced in a direction of separation from a joint surface of the other shape, and fittings.SOLUTION: In a shape joining structure, a left end surface 12a of a sill 12 is joined to a joint surface 13a of a left jamb 13 in the state of interposing a sealant 30 made of an elastic material. A swelling material 40 made of a water-absorbent resin is interposed between the left end surface 12a and the sealant 30. Preferably, the swelling material 40 is applied to a surface of the sealant 30. |
