Each of the upper fixed piece 30 a and the lower fixed piece 30 b is provided with a protruding strip portion 33 that protrudes to the back side so as to fit into the concave strip portion 23.

上記の第三の構成を備えることで、第三の態様の折板屋根材の取付構造では、係止部材３の凸条部３３が脚部２１の凹条部２３に嵌まることによっても、係止部材３の位置ずれを抑えることができる。ここで、タイトフレーム２の凹条部２３に対して、係止部材３の凸条部３３が自身の長手方向に沿って長く嵌まるため、係止部材３の脚部２１の幅方向への位置ずれが効果的に抑えられる。したがって、第三の態様の折板屋根材の取付構造では、一対の突片３２に加えて凸条部３３によっても係止部材３の位置ずれを抑えることができ、タイトフレーム２から係止部材３がさらに外れにくい。 By providing the third configuration described above, in the folded structure of the folded roof material according to the third aspect, the convex strip portion 33 of the locking member 3 is fitted into the concave strip portion 23 of the leg portion 21. The positional shift of the locking member 3 can be suppressed. Here, since the convex strip portion 33 of the locking member 3 is fitted to the concave strip portion 23 of the tight frame 2 along the longitudinal direction of the tight frame 2 in the width direction of the leg portion 21 of the locking member 3. Misalignment can be effectively suppressed. Therefore, in the mounting structure of the folded roof material according to the third aspect, the positional deviation of the locking member 3 can be suppressed by the protruding strip portion 33 in addition to the pair of projecting pieces 32, and the locking member can be stopped from the tight frame 2. 3 is more difficult to come off.
