PROBLEM TO BE SOLVED: To provide a sealing structure of a water meter system, improving a work efficiency for assembling the water meter system. SOLUTION: In this sealing structure of the water meter system 100, a plurality of holding projections 122 are formed protrusively from a groove inside surface 121A on the inside out of a circular sealing storage groove 121 formed on the outer peripheral surface of a meter body case, and each holding projection 122 presses and holds a circular sealing member S2 between the groove inside surface 121B on the outside and itself. Hereby, before inserting the water meter 20 into an inner cylinder case 31, the circular sealing member S2 is held in a three-dimensionally curved shape along the outer peripheral surface of a meter body case 120, and is stored in the circular sealing storage groove 121 over the whole circumferential direction. Consequently, the water meter 20 is inserted smoothly into the inner cylinder case 31 to improve the work efficiency for assembling. COPYRIGHT: (C)2011,JPO&INPIT
