To solve such a problem that although a lower basin of a meter box has been conventionally utilized as a base which fixedly fits a meter unit into the meter box, the meter box is weighted with water pressure or the like, thus a certain strength is required for the lower basin and the weight of the meter box is increased, resulting in being disadvantageous in terms of material cost and also working efficiency.

A primary joint member 3 and a secondary joint member 4 of a meter for water service for fixedly fitting a meter unit are respectively set to a primary side and a secondary side of a frame body 1 fitted to the inner edge 21a of a lower basin of a storage box of the meter for water service, and the meter unit is fixedly fitted by a unit frame configured so as to detachably attach the meter for water service.
