A liquid substance advancing container that stores a liquid content in a reservoir provided in a barrel body, moves a piston in the reservoir forward by turning a handle of a rotational body exposed from a rear end of the barrel body, relative to the barrel body, to advance the content to a front end of the barrel body, wherein the piston is formed of a sealing part in a front part of the piston that comes in sliding contact with an inner wall of the reservoir of the barrel body and a bar member in a rear part of the piston that has a threaded section on an inner periphery or an outer periphery, is movable in an axial direction and is restrained from moving with respect to a rotational direction, a front bar-like part extended forward from the handle is formed with a threaded section that is directly or indirectly screw-fitted to the threaded section of the bar member in the rear part of the piston, wherein as the handle is rotated relative to the barrel body, the front bar-like part advances and then after full advance of the front bar-like part the piston can extend and retract relative to the front bar-like part, characterized in that the liquid substance advancing container includes a rear sleeve that is screw-fitted on an outer periphery of the front bar-like part and screw-fitted into an inner periphery of a threaded section of the rotational body, an elastic part is provided between the rotational body and the front bar-like part, a cup-like socket that is open on a front side and closed on a rear side is provided inside the rotational body in order to receive a rear end of the elastic part, and a rear part of the rear sleeve is formed so as to be able to receive the elastic part held in the socket so as to press the rear sleeve forward. the piston is formed of a sealing part in a front part of the piston that comes in sliding contact with an inner wall of the reservoir of the barrel body and a bar member in a rear part of the piston that has a threaded section on an inner periphery or an outer periphery, is movable in an axial direction and is restrained from moving with respect to a rotational direction, a front bar-like part extended forward from the handle is formed with a threaded section that is directly or indirectly screw-fitted to the threaded section of the bar member in the rear part of the piston, wherein as the handle is rotated relative to the barrel body, the front bar-like part advances and then after full advance of the front bar-like part the piston can extend and retract relative to the front bar-like part, characterized in that the liquid substance advancing container includes a rear sleeve that is screw-fitted on an outer periphery of the front bar-like part and screw-fitted into an inner periphery of a threaded section of the rotational body, an elastic part is provided between the rotational body and the front bar-like part, a cup-like socket that is open on a front side and closed on a rear side is provided inside the rotational body in order to receive a rear end of the elastic part, and a rear part of the rear sleeve is formed so as to be able to receive the elastic part held in the socket so as to press the rear sleeve forward.
