PROBLEM TO BE SOLVED: To provide a structural member for a water storage tank, which increases usefulness even if this structural member has a function for fitting in a cylindrical leg. SOLUTION: This structural member is constituted by forming a base 12 and the cylindrical leg 13 erected on the base 12 by integrally resin molding them. Fitting parts 14 for fitting end parts of the cylindrical legs 13 in each other are formed in the end parts of the cylindrical legs 13, respectively. The fitting parts 14 are formed into a recessed and projecting shape formed by connecting a first end wall 14a with a second end wall 14b positioned on a terminal side more than the first tip wall 14a like steps. A rib 16 in the leg extended from an inner face of the second end wall 14b to the terminal side is formed on an inner face of a side wall 15 of the cylindrical leg 13. COPYRIGHT: (C)2009,JPO&INPIT
