The present invention relates to a water meter protector, and more specifically, to a heat insulation chamber (1b) made of expanded polystyrene inside the synthetic resin protector (1) and a water meter (4) therein to cover the upper lid of the water meter In the well-known thing which covers (1c) and covers the outer cover 3 made of polystyrene foam on the exterior of the protective container 1, the circumferential wall part between the inner insulation chamber 1b and the outer cover 3 is expanded to the outside, 1a) is formed and another one of the foam polystyrene intermediate lid (2) with a handle (2a) to be caught on the stepped by the middle lid (2) between the inner insulation chamber (1b) and the outer cover (3) By forming a double heat insulation chamber (1 ga) (1 b) up and down, it is possible to provide a practical water meter protection box that can be used in both cold and warm regions as a single protection tube, which does not significantly increase the cost burden. that to be.
