  • Patent number: 5553956
    Abstract: A stick-shaped material propelling device is comprised of a first tubular body and a spiral shaft inserted in the first tubular body. The spiral shaft has a spiral groove on the circumference of spiral shaft and an integral guide portion at a rear portion of the spiral shaft. The guide portion engages an inside portion of the first tubular body so that the guide portion is unturnable, but is movable in the axial direction relative to the first tubular body. A holder for holding a stick-shaped material is provided at a front portion of the spiral shaft. A second tubular body is turnably mounted on the first tubular body. The second tubular body has a projection on the inside of a rear portion of second tubular body. The spiral shaft and the holder are inserted into the second tubular body so as to be able to slide in the second tubular body with the projection engaging the spiral groove. At least one slit is formed around the projection on the second tubular body or in an end portion of the spiral shaft.
