A container main body and a cap are stably and detachably engaged while improving a productivity. A leading end portion of a tubular container main body is provided with one or more projection portion on an outer peripheral surface, a hole communicating inner and outer sides of a tube in a rear side in an axial direction of the projection portion, and an expanded portion expanded such that an outer diameter within the tube is equal to or more than an outer diameter of the projection portion and running to a rear side in a rear side in an axial direction of the hole, respectively. An inner peripheral surface of a cap is provided with an annular projection detachably engaging with disengaging from the projection portion in an axial direction. The projection portion securely climbs over the annular projection for its flexibility in a diametrical direction of the hole.

To generate a sense of click according to the movement of a moving member, reset screwing sections to screw in when a screwing action of the screwing sections is released, and reduce the number of components. In a container, when a main body cylinderand an operation cylinderare relatively rotated in an extending direction and relatively rotated in a retracting direction, a female screw memberand a moving memberrelatively rotate, the moving membermoves forward and moves backward according to a screwing action of screwing sections, and click teethandalso relatively rotate in synchronization with each other. Since an elastic bodyurges the click teethtoward the click teeth, a sense of click is given when the moving membermoves forward and moves backward. In addition, when the moving membermoves backward according to the relative rotation and a screwing action of screwing sectionsis released, the elastic bodyurges the screwing sectionsto be reset to screw in according to the relative rotation in the opposite direction. In other words, the elastic bodyis shared to realize the giving of a sense of click according to the movement of the moving memberand the reset for screw-in of the screwing sections
