いることを特徴とする筆記具。 an outer cylinder having a tip; a lead friction locking portion provided within the tip to engage and hold the feeding core with frictional force;
A lead guide portion provided on the inner circumferential surface of the distal end side of the outer cylinder and protruding in the inner radial direction and having a chuck guide step at the front end, a core pipe inserted into the outer cylinder so as to be slidable in the axial direction, and the core. A lead chuck connected to the tip of the pipe and urged in the backward direction together with the core pipe and slidingly in contact with the lead guide portion; and a chuck provided at the tip of the lead chuck via a hinge so as to be openable and closable in the radial direction. When the lead chuck moves forward, the chuck piece separates from the chuck guide step and is pushed open from the inside in the outer radial direction by the feeding core before reaching the lead friction locking portion, and when the lead chuck retreats, the chuck guide step moves away from the chuck guide step. When the lead chuck moves forward, the feeding core is inserted into the tip and is frictionally engaged with the lead friction locking portion, and then when the lead chuck moves back, it is pressed against the feeding core. A writing instrument characterized in that the writing instrument is opened by frictional resistance with a stationary feeding lead which is held in frictional engagement with the lead friction locking part before reaching the chuck guide stepped part.
