Abstract
A travelling section for retaining the stick type cosmetic material is installed rotatably in an axial direction in an outer shell section which is constituted by rotatably connecting a front cylinder and a base cylinder An outer circumferential surface of a spiral cylinder which is spirally engaged with a male screw section of the travelling section fits in a second slide surface provided on an inner circumferential surface of the base cylinder which is one component of the outer shell section Due to frictional force of this fit-in part, a cylindrical body and the spiral cylinder are synchronously rotated. The travelling section is engaged with an inner circumference of the front cylinder and can slide only in an axial direction. When the travelling section reaches the uppermost limit or the lowermost limit by relative rotations of the front cylinder and the base cylinder if further rotary torque is furnished, synchronously rotating means are released and the base cylinder and the spiral cylinder are raced.
