A telescopic meter box disclosed in Japanese Patent Publication is also proposed. This meter box connects the meter (water meter) and the water stopcock on the movable side, and the tap water inlet and tap water outlet on the fixed side with a coiled pipe that expands and contracts. By extending the meter upwards, the meter and the water stopcock can be raised so that the meter can be replaced on the ground. However, this type of meter box has a problem that the product cost of the water meter itself is significantly increased because the meter box is relatively long and requires special coiled piping, and the entire equipment is large and large.
