Claims

[Claims for Utility Model Registration] (1) A first member comprising a pair of threaded tongues protruding from one end surface so as to form a recess in the extending direction thereof, and a projection protruding from the one end surface. a cylindrical body; one end of the hollow cylindrical body is provided with a threaded inner wall; the other end is provided with a closed end surface portion;
a second cylindrical body that is screwed into the cylindrical body; an annular component that has a through hole on one end face and is open on the other end face into which the second cylindrical body is inserted; and an enlarged end portion on one end; A control rod having a concave end at the other end and inserted into the annular part from the open end face thereof, and a rubber hose that prevents the hose from being directly pressed against a part of its outer periphery. The ring is wrapped around the
and a rubber hose inserted into the recess of the first cylindrical body together with the rubber ring and held between the concave end of the control rod and the protrusion of the first cylindrical body, and a hard rubber rod inserted into the rubber hose. , a liquid flow rate regulator consisting of a pair of connectors attached to both ends of the rubber hose. (2) The liquid flow rate regulator according to claim 1, wherein the enlarged end of the control rod is shaped so as to come into contact with the closed end surface of the second cylindrical body at one point.
