Provided is a landing jamb in which a design plate (8) is stacked on a surface of a jamb body (5), the design plate being a flat plate having a plate thickness greater than that of the jamb body. The design plate (8) is fixed to the jamb body (5) by a plurality of sets of fixtures. At least one set of fixtures includes a stud bolt (12), a main nut (13) that is fastened to the stud bolt (12), and intermediate members (14, 15, 16) through which the stud bolt (12) is made to pass and which are interposed between the main nut (13) and the jamb body (5). The melting point of a material constituting the intermediate members (14, 15, 16) is lower than the melting point of a material constituting the stud bolt (12) and the main nut (13). |
