<p><P>PROBLEM TO BE SOLVED: To provide a rotational delivery type multi-core writing utensil capable of preventing projection of a writing tip end of a writing body from a tip end opening part of a shaft cylinder when retracting writing tip ends of all writing bodies stored in the shaft cylinder into the tip opening part of the shaft cylinder. <P>SOLUTION: A small diameter part 11b is formed in the rear of a sliding case 11, a flange part 11c is formed in the rear of the small diameter part 11b, and a plurality of recessed parts 11d, 11e, 11f, 11g, 11h, 11i are formed radially in the front face of the flange part 11c. A plurality of inward projections 12e, 12f, 12g are radially formed on the inner face of a cam cylinder 12 formed with a rotational cam 12a. A slit 12h is provided around the inward projection 12e of the cam cylinder 12, a tongue-shaped elastic deformation part 12i is formed, and the inward projection 12e is positioned on the elastic deformed part 12i. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
