PURPOSE:To enhance productivity by providing sufficient clamping forces at a leading barrel and a rear barrel and to simply regulating molds. CONSTITUTION:A connecting structure of a leading barrel to a rear barrel of a liquid container 4 comprises a plurality of annular protrusions 181, 182 and a plurality of annular recesses 201 and 202 which are engaged when an insertion 14 of a leading barrel 8 is inserted into a hollow part 16 of a rear barrel 12 at an insertion periphery 14a of the barrel 8 of a felt pen and hollow inner peripheral surfaces 16a of the barrel 12 in such a manner that at least a pair of peripheries corresponding to partial peripheries disposed at right and left sides of the plurality of the protrusions 181, 182 and the recesses 201, 202 are engaged tightly when the insertion 14 of the barrel 8 is inserted into the hollow part 16 of the barrel 12. |
