When a main body tube and an operation tube in the container are relatively rotated toward a first direction, a moveable screw tube advances for a predetermined amount, and when relative rotation is further carried out toward the first direction, a screwing part exerts screw function to urge a moving body forward. In the container, a front end part of a female thread of the screwing part in the moveable screw tube is radially outwardly expandable via a slit, so that the so-called pulling perforce can be performed in the case that the female thread is formed by using a core pin for instance. Moreover, when the moveable screw tube advances for a predetermined amount through relative rotation toward the first direction, the outer diameter of the front end part is restricted and expansion thereof is hence prevented, so that, when relative rotation is further carried out toward the first direction and the screwing part exerts screw function to urge the moving body forward, it is possible to suppress expansion of the front end part and hence expansion of the female thread of the screwing part. Accordingly, the screwing part reliably exerts screw function when the moving body advances. | 2010-04-29 |
