<p>[PROBLEMS] To provide a sprinkler head cover comprising a cylindrical retainer in which a sprinkler head is stored and a plate-like cover plate connected to the lower end of the retainer, in which water-sprinkling by the operation of the sprinkler head is not obstructed without lowering the strength of joining of the retainer to the cover plate. [MEANS FOR SOLVING THE PROBLEMS] A plurality of legs (6) extending downward from the lower end of the retainer (1) are so bent that their tip ends are made horizontal. The cross sectional area of the downwardly extended portion (9) of the leg (6) is smaller than that of the horizontal portion (7) of the tip end. Otherwise, the legs (6) are downwardly extended in the diagonal outer direction and so bent that their tip ends are made horizontal.</p> |
