自動繰出式シヤープペンシル。 a cap; a slider built into the cap so as to be slidable in the longitudinal direction and urged forward in the longitudinal direction;
It consists of a lead holder that is integrated or fixed to the slider and holds the lead with moderate force, and a chuck that comes into contact with the tapered surface of the fastener and allows the lead to move forward but prevents it from retreating due to a wedge action. In an automatic mechanical pencil that automatically feeds out the lead, a spring body is constructed by separating a front elastic part and a rear elastic part, which has a weaker elasticity than the front elastic part, by an inelastic part, and the inelastic part of the spring body is fixed in the cap, the slider is biased longitudinally forward by the front elastic part of the spring body, and the chuck is biased longitudinally rearward by the rear elastic part. pencil.
