A fitting structure includes a shaft member of metal provided at the leading end part thereof with check projections formed integrally thereon, and a cap of synthetic resin formed of a main body and a lid member. The main body is provided therein with an insertion groove permitting insertion therein of the leading end part of the shaft member provided with the check porjections. The insertion groove is adapted to be closed by the lid member of the cap. Owing to this structure, the cap can be fitted to the leading end of the shaft member by a single operation of closing the insertion groove with the lid member. The fitting work involved in the structure of this invention, therefore, is extremely simple. While the cap is formed of the two component parts, i.e. the main body and the lid member, neither the main body nor the lid member is required to have any screw thread therein. Thus, the metal mold to be used for the formation of the cap is inexpensive and the cap itself can be produced inexpensively. |
