PURPOSE: A freezing protective device for a water meter is provided to block an influence of an outside temperature authentically by an insulator surrounding a whole pipe-line and a water meter accurately. CONSTITUTION: A freezing protective device for a water meter comprises a pipe-line coat portion (20), a meter coat portion (30), and a meter cover portion (36). In the pipe-line coat portion, a first base and a second base are combined in a bonding wire, and an internal space in which an insulator etc. is filled is formed. Multiple internal spaces are segmented by a compartment bonding wire, and cover a lower part of a pipe-line and a meter. The meter coat portion covers an outer side surface of the meter. The meter cover portion covers an upper side of the meter. |
