Claims

[Scope of utility model registration request]

It has a large-diameter hollow part inside, a small-diameter through hole in the lower part, an enlarged adjustment groove is formed in the middle of the through hole, and a water supply inlet communicating with the adjustment groove is provided, and the through hole is open. The main body has a sealed end, and the spring receiver is integrated with a ring and a water pressure regulator, and the ring and the regulator are slidable into the hollow part and the through hole, respectively. A movable ring having a flow hole with a spring sandwiched between the ring and the movable ring is slidably fitted into the hollow, and a water amount adjusting rod to which an eccentric cam is fixed is fitted onto the circumferential surface of the cam. The rod is rotatably supported by the main body so as to rest on the end surface of the movable ring, and a motor for driving the rod is provided outside the main body, and the adjuster has a stepped cylindrical shape. A flow rate control device for a proportional control type gas water heater, characterized in that the adjustment groove has a wedge-shaped opening extending downward from the upper incisal edge, and a through hole is provided directly below the step.
