筆記具。 A core pipe 3 that is slidably housed in this outer cylinder 1 and is provided with a core extrusion mechanism 8, a center shaft 2 that houses this core pipe 3, and an impact between this center shaft 2 and the above-mentioned outer cylinder 1. The first elastic body 5 and the core pipe 3
and an advancement/retraction mechanism 4 which is disposed at a predetermined position on the center shaft 2 and moves the core pipe 3 and the center shaft 2 forward or backward; When the pipe 3 is in the retracted position, it is provided with a core bite regulation mechanism 22 that restricts biting of the core 19 by the core extrusion mechanism 8, and the core bite regulation mechanism 22 has one end 23b that is attached to the center shaft 2.
A lock pin 23 is fixed to the inner shaft 2 and moved back and forth integrally with the inner shaft 2, and a lock pin 23 is fixed inside the outer cylinder 1 and is moved back and forth when the inner shaft 2 is moved rearward.
and a lock cam 24 for locking the other end 23c of the 3 to the core pipe 3 to restrict rearward movement of the core pipe 3.
