Claims

[Scope of utility model registration request]

A guide tube with a spiral cam groove on its outer surface, a sliding piece that is slidable on the guide tube and has a writing body connected to its tip;
A cylindrical cam having a circumferential cam slope in contact with the sliding piece, and a cylindrical cam that is integrated with the cam in the rotational direction and is rotatable with respect to the guide cylinder, and the entire portion of the clip described later is retractable. A cap has a chamber for storing an elongated hole and a mounting leg of the clip, and has a working part at the tip and a mounting leg at the rear end, and the working part is fitted into the cam groove of the guide tube and the mounting leg The clip has a movable fulcrum part, and when the sliding piece is advanced by the rotation of the cylindrical cam and the writing body is protruding, the working part of the clip hits the lowest point of the cam groove of the guide tube. At the same time, the fulcrum part of the mounting leg comes into contact with the deep stepped part of the chamber, making the entire clip retracted, and the rotation of the cylindrical cam causes the sliding piece to retreat, allowing the cursive to be stored in the clip. is in contact with the uppermost point of the cam groove of the guide tube, and at the same time, the fulcrum of the mounting leg moves to and comes into contact with the shallow stepped portion of the chamber, thereby bringing the entire lip into a floating state. A rotary writing instrument.
