ことを特徴とする複式筆記具。 A resin molded guide cylinder having a pair of guide grooves, an engaging part on the outer surface of the front end cylinder part, and a circumferential groove on the outer surface of the rear end boss part, and a resin molded guide cylinder with an integral engaging part on the inner surface. A resin molded product with a front shaft and a cam slope displacing in the axial direction in a circumferential manner at the front end, a collar protruding from the inner surface behind it, and a fixing part for the cap on the outer surface. It is equipped with a cylindrical cam, a resin molded cap with a fixing part for the cylindrical cam on the inner surface, and a pair of writing bodies each having a sliding piece attached to the rear end. The guide tubes are fitted into the grooves so as to be movable in the axial direction and biased backward by return springs, and the front end tube portion of the guide tube is inserted into the interior of the tip shaft, and the engaging portions of the two are engaged with each other. The cylindrical cam is placed over the outer periphery of the second half of the guide cylinder, the cam slope at the front end is brought into contact with the sliding piece, and the collar is elastically deformed into the circumferential groove of the guide cylinder. The cylindrical cam is inserted into the inside of the cap, and the fixed parts of both are fitted together to prevent rotation and removal, and the cap can be moved axially relative to the tip shaft and circumferentially. A double writing instrument characterized by being able to rotate freely.
