PROBLEM TO BE SOLVED: To provide a constitution, in which a sleeve and a hydrant box can be connected unforcedly even when the sleeve is drawn obliquely around the hydrant box. SOLUTION: The hydrant box is used when a feed pipe and a hydrant piped by a sleeve piping system are connected through an elbow joint. In the hydrant box, a box body in which the joint is housed and a plate for fixing the box body onto a wall surface or the like are configured separately. The box body is installed to the plate by selecting one of a plurality of previously specified angles.
