たことを特徴とする多芯筆記具。[Claim for Utility Model Registration] A plurality of writing bodies such as ballpoint pen leads are housed in a barrel whose rear shaft and front shaft are connected by a joint, and the writing part at the tip of the writing body is selected from the opening at the tip of the barrel. In a multi-lead writing instrument that protrudes uniformly, a locking through hole is bored in the rear shaft, and a shallow annular locking recess or a low annular locking protrusion is formed on the inner surface of the front shaft. A low annular locking protrusion or a shallow annular locking recess is formed on the lower outer peripheral surface of the joint, and is formed by two grooves cut from the upper edge of the joint. A locking step is protrudingly provided at the tip of the elastic rod, and the locking step engages with the locking through hole of the rear shaft, and the locking protrusion or locking recess of the joint locks the front shaft. A multi-core writing instrument characterized by engaging with a recess or a locking protrusion with a weak fitting force.
