This is characterized by sandwiching the cap 5 between them.

According to the roof structure of the present invention having the above structure,
Since the bent part of the side edge of the metal roof plate is directly attached to the receiving member fixed to the roof structure without using a lower hanger etc., the lower hanger etc. are unnecessary and the parts Points can be reduced.

Further, in the roof structure of the present invention, after the receiving member is fixed to the roof structure, it is only necessary to place the bent portion of the metal roof plate in the concave portion of the receiving member and fix it by the pressing member. The metal roof plate can be connected and fixed under a simple operation without a troublesome operation of inserting and arranging the suspender below the fixing member and hooking the hanging member on the fixing member.

Further, since the receiving member used in the roof structure of the present invention is a short block-shaped part as illustrated in FIG. 3, it does not need to bend a long object and can be easily formed by, for example, pressing. Can be manufactured.

In the roof structure of the present invention, a receiving member having a structure in which the height of the concave portion can be freely changed (see FIGS. 7 and 8) may be used. With the use, even if the distance between the top of the roof structure and the metal shingle is large and the dimensions between them vary widely,
By adjusting the height of the receiving member, it is possible to prevent the receiving member from being in an uneven state with respect to the roof structure.

Here, according to the roof structure of the present invention, although there is usually no problem, for example, due to a strong wind due to a large typhoon or other causes, the metal roof plate 1 is extremely moved in the direction of the arrow shown in FIG. When the metal roof plate 1 is pulled with a large force, the bent portion 11 of the metal shingle 1 may be deformed, and in a severe case, the bent portion 11 may fall out of the concave portion of the receiving member 2, which may cause a problem.
