摘要

A sprinkler head includes a checking means for checking from the outside that fluid such as fire protection water has been filled inside of a sprinkler head body. A method for checking that the fluid such as fire protection water has been filled includes providing a movable rod inside of the sprinkler head body in such a manner as to be moved backward and forward when the fluid has been filled inside of the sprinkler head body, and checking that the fluid has been filled inside of the sprinkler head body by observing a position of the movable rod from the outside.
