ABSTRACT:
The liquid container includes a body for having a tank portion housing a liquid, and having a supply port on a tip end side, a piston for moving forward inside the tank portion, a piston rod connected with the piston and extending rearward, a manipulating cylinder rotatably mounted to a rear portion of the body, and a rotation stopping cylinder unrotatably disposed in a rear inner portion of the body. A conversion mechanism for converting relative rotation between the manipulating cylinder and the body into movement of the piston rod in an axial direction with respect to the body is provided between the manipulating cylinder and the rotation stopping cylinder, and a rotating direction restricting mechanism for restricting the rotating direction of the manipulating cylinder and the body to one direction is provided. The manipulating cylinder and the rotation stopping cylinder are integrally connected by fitting the annular raised portion formed on the rotation stopping cylinder into the annular recessed portion formed on the manipulating cylinder.
