<p>A rotary-cam ball-point pen having an outer sleeve (1), a rotary-cam mechanism (5) comprised of a cam body (2) provided on the inside of the outer sleeve, a rotary-cam (2) engaging the cam body, and a cam bar (4) engaging the rotary-cam, and a refill (7). The rear portion of the refill is loaded backward by an elastic body (6) inserted into the rotary-cam. The cam bar has a structure with flexibility in which the cam bar can be distorted inward by applying a radial force. Since the cam bar is inserted into the outer sleeve from the rear side of the outer sleeve, it is possible to form a clip (21) of an integral part of the cam bar, or a decoration (22) having dimensions larger than the outside diameter, or a knocking cap.</p> |
