ンシル。 The rotation of the rear outer cylinder 1b, which is rotatably and detachably connected to the rear end of the front outer cylinder 1a, causes the core delivery mechanism 6 housed in the front outer cylinder 1a to operate in a related manner. In the sharp pencil that performs the feeding described in No. 2, there is a rotary cam mechanism 9 which is disposed behind the lead feeding mechanism 6 and causes the lead feeding mechanism 6 to perform a lead feeding operation, a cam 20 of the rotating cam mechanism 9, and a cam 20 of the rotating cam mechanism 9 and the rear outer part. A sharp pencil comprising a driver 18 that connects and fixes the barrel 1b, and the lead feeding mechanism 6, the rotary cam mechanism 9, and the driver 18 are formed so that they can be assembled by being dropped from the rear of the outer barrel 1. .
