摘要:PROBLEM TO BE SOLVED: To solve problems in which an opening which opens a window hole to a rear side and which can be opened and closed freely is disposed, and an operation body can be detached from a barrel and inserted into the barrel via the opening so that respective writing bodies can be detached from the inside of the barrel and replaced in a multi-refill writing instrument, in which because the window hole is opened to the rear side, the window hole is shrunk during molding and periphery of the window hole is deformed, and as the result it is difficult to attach a slider to the window hole and when it is attached to the window hole forcibly, crack occurs on the barrel on the peripheral part of the window hole.SOLUTION: The multi-refill writing instrument has plural window holes formed on a rear part of a barrel, each of the window holes has a slider capable of moving forward and backward, and a writing body is disposed in front of the slider. When a front part and rear part of the window hole are closed, the slider passes through an inner shape of a rear end opening of the barrel.
