A front cylinder and base are rotatably connected. Relative rotations cause stick-type
cosmetic material retained by a core chuck member to slide forward and backward
along an axial hole of the cylinder. Axially extending first slide grooves along
an inner circumference of the hole have an inside diameter almost equal to a diameter
of the material. Second grooves, deeper than the first, extend continuously from
ends of the first grooves. Claws at a front-end section of the chuck retain the
material and are slidably guided by the grooves. Back surfaces of the claws slide
into contact with bottoms of the first grooves. Inner surfaces of the claws almost
coincide with an inside diameter of the hole. If the material is loaded in the
chuck with the claws at the second grooves, the claws elastically deform outward
and the claws receive the material. With the claws at the first grooves, the claws
tightly sandwich the material.
