PROBLEM TO BE SOLVED: To prevent a thick, flat roof tile from moving and floating by using a structure of higher reliability to lock and stop the head of a receiving part using the hip of the receiving part. SOLUTION: A locking receiving part 2 is provided at an end near the head T of the receiving part U and a locking protrusion 3 is provided on the hip part R. When the roof tiles are combined, the receiving part 2 of the upper roof tile is made to abut the locking protrusion 3 of the lower roof tile to lock the roof tiles together, with the roof tiles stopped either directly or by locks 9. The roof tiles are prevented from being lifted up and moved in storms to prevent intrusion of rainwater and the roof tiles can be easily and quickly installed.
