PROBLEM TO BE SOLVED: To provide a meter unit capable of press-fitting/fixing a water service meter in a centering state while exhibiting the stopper function and the rotation prevention function of a primary side press-fitting part, and capable of replacing a sealing O ring by removing only the press-fitting part without attaching-detaching a mechanism for exhibiting the stopper function and the rotation prevention function and the whole primary side support mechanism, from a base body. ! SOLUTION: An upstream side first support mechanism 6 and a downstream side second support mechanism 7 for press-fitting/fixing the water service meter 8, are provided on both sides in the longitudinal direction of the base body 2, and a slide member 20 for press-fitting/fixing one end part 8a of the meter 8 is provided in the first support mechanism 6 so as to freely advance-retreat along the meter press-fitting direction. A pin 15 for preventing rotation by locking on this slide member 20, is arranged in a position for |
