Abstract
A travelling section 30 for retaining the stick type cosmetic material is installed rotatably in an axial direction in an outer shell section 2 which is constituted by rotatably connecting a front cylinder 10 and a base cylinder 20. An outer circumferential surface 43 of a spiral cylinder 40 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 20 which is one component of the outer shell section 2. Due to frictional force of this fit-in part, a cylindrical body and the spiral cylinder 40 are synchronously rotated. The travelling section 30 is engaged with an inner circumference of the front cylinder 10 and can slide only in an axial direction. When the travelling section 30 reaches the uppermost limit or the lowermost limit by relative rotations of the front cylinder 10 and the base cylinder 20, if further rotary torque is furnished, synchronously rotating means are released and the base cylinder 20 and the spiral cylinder 40 are raced.
