To provide an easily-manufacturable, inexpensive and easily-attachable wind-resistant reinforcing fitting for a tile, which is composed of a simple structure, which dispenses with the penetration of a nail through a sheathing roof board and which can bring about a strong wind-resisting force, and a wind-resistant reinforcing structure of a base tile.

Characteristically, the wind-resistant reinforcing fitting 1 for the tile comprises a fixing portion 2 in which a nail hole 2a is drilled, and an arm portion 3 which is equipped with a pressing portion 3a for pressing a tile surface to a downside. The wind-resistant reinforcing structure of the base tile is characterized as follows: a tile tail of the base tile is latched to battens for holding tiles, or installed on the sheathing roof board; and the nail is inserted through the nail hole of the wind-resistant reinforcing fitting for the tile and that of a flashing protrusion, and driven into the battens for holding tiles or the sheathing roof board, so that the base tile can be held by the fixing portion and pressing portion of the wind-resistant reinforcing fitting 1.
