A hollow cylindrical sealing sleeve is arranged on the end face of the wax container and has a hole through which the drive rod passes. A plurality of triangular shaped projections is formed on the inner wall of the hole of the sealing sleeve. A spring cap is fitted onto the sealing sleeve for pressing the triangular shaped projections onto the drive rod due to the spring force of the spring cap.
