A heat insulator rising blocking device of a water meter protection case is provided to mount a blocking piece on the container rim without a separate fastener by using the blocking piece which can be folded and stretch out. A heat insulator rising blocking device of a water meter protection case comprises a water meter protection case(1) with flat inner surface, a heat insulator covered with a synthetic resin reinforced cover(8), a rim having a plurality of fixing holes(5,5') and a rail groove, and a blocking piece(12) having protrusions(13,13') inserted into the rail groove. A cut part(9) is formed on one side of the rim so that the rim is folded to be inserted in the container and stretches out to be fixed there. The heat insulator is separated from the inner surface of the container by the rim. |
