Claims

[Scope of utility model registration request]

Ends of a pair of lead wires connected to an external circuit and at least one hook are disposed through a wall of a retaining ring disposed in the fluid passageway, and at least one hook is disposed within the retaining ring. In a hot wire type flowmeter in which a hot wire is strung between ends of the lead wire and is hooked to the hook midway, the hot wire attachment portions of the lead wire and the hook are housed in the inner circumferential surface of the retaining ring. A hot wire type characterized by the formation of a recessed part to
