ABSTRACT:
A writing tool in which a core casing (3) or (3a) is inserted in an outer sleeve (2), and an end (6) of core casing (3) or (3a) can be projected out of the end of outer sleeve (2) by operating end (4a). End 6 of core casing (3) or (3a) can be withdrawn by reverse operation of the operating end (4a). A revolution-to-linear movement conversion arrangement for converting a revolutional movement of an operating end (4a) to a axial movement between a core casing (3) or (3a) and an outer sleeve (2) is provided. A retracting spring (5) between the outer sleeve (2) and the core casing (3) or (3a) and the operating end (4a) projecting out of a rear end of the outer sleeve (2) can be forcibly operated against the force of a retracting spring (5). The operating end (4a) is integral with the rear end of the core casing (3) or (3a), with a boss 9 provided on an outside of a rear portion of the core casing (3), (3a) or inner sleeve (31), and a helical slit, slot or groove (12c) provided at the rear end of the outer sleeve 2, said boss (9) fitting into the helical slit, slot or groove (12c). A rear part (41a) of the outer sleeve (41) having smaller diameter and a rear sleeve 47 of the same diameter to said outer sleeve 41 is mounted on the rear part (41a) for cigarette-like appearance.
