PROBLEM TO BE SOLVED: To provide a liquid discharger that can control linearly discharge amounts and moreover complete the control by almost one rotation thereof. ! SOLUTION: A liquid discharger 1 comprises: a supply hole member 2 to be connected to a supply source of liquid; a liquid injection hole member 3 that is connected to the supply hole member 2 and injects liquid to an object to be injected with the liquid; a liquid flow path 4, provided in an inner space between the supply hole member 2 and the liquid injection hole member 3, into which the liquid flows; an opening/closing member 5 for opening and closing the liquid flow path 4; and an operating member 6 that operates the opening/closing member 5. The opening/closing member 5 is reciprocally moved in the liquid flow path 4 by a cam mechanism. The cam mechanism has a cam groove provided on an outer periphery of the opening/closing member 5 and a protrusion that is provided in the operating member 6 and fitted to the cam groove, where rotation ran |
