PROBLEM TO BE SOLVED: To provide a coupling structure between a writing body and a sliding member, in which a shaft of the writing body is simply caulked and fixed to the sliding member to allow the sliding member and the writing body to mutually oscillate and tilt while preventing the fixed state by caulking from being loosened with the elapse of time due to writing pressure during writing. SOLUTION: Two circular protruding walls 10d respectively having a circular projection shape and facing each other are formed at the upper end of a shaft 10a. After a connecting part 11e of a sliding member 11 is loosely fitted to the shaft 10a, the circular protruding walls 10d of the shaft 10a are brought into contact with a plane 11g of the sliding member 11. In that state, caulking is applied, from the outer side of the shaft 10a, at the position in the shaft 10a being lower by the radial distance of the circular protruding wall from the upper end of the circular protruding wall to oscillably fix the shaft 10a to the sliding member 11.
