Claims

[Scope of utility model registration request]

The structure is such that a cap is detachably attached to a main body having a pen tip at its tip, the cap consisting of an outer cap and an inner cap, and an inner wall such that the inner cap bears at least a part of the fitting force with respect to the main body. The fitting part has a fitting part, and the material thereof is made of polyolefin resin, and further, an elastic ring is arranged around the outer periphery of the fitting part so as to have a gap between it and the inner wall of the outer cap. A cap mounting structure wherein the elastic ring imparts inward elasticity to the inner cap at least when the cap is mounted on the main body.
