PROBLEM TO BE SOLVED: To provide a multi-refill writing instrument in which the degree of freedom in design of an operation body is greatly increased, and which can surely prevent operation bodies from entangling with each other in an aggregation state of the operation bodies.SOLUTION: A plurality of writing bodies 6 are accommodated in a barrel 2 in a manner movable in the forward/backward direction. An operation body 7 is connected to a rear end of each writing body 6. An operation part 71 of the operation body 7 is made to protrude from a window hole 41 outward in a radial direction. The operation body 7 includes an engagement part 74 which is engaged with a rear end opening of the writing body 6. The operation part 71 of the operation body 7 includes a through-hole 71a penetrating in the thickness direction. The diameter of an inscribed circle A of the through-hole 71a is formed to be smaller than the diameter of a circumcircle D of the engagement part 74. A decorative part 76 is provided in front of the operation part 71. The decorative part 76 has a through-hole 76a penetrating in the thickness direction. The diameter of an inscribed circle B of the through-hole 76a of the decorative part 76 is formed to be smaller than the diameter of the circumcircle D of the engagement part 74. |
