Claims

[Scope of utility model registration request]

A sliding fastener is placed on the outer periphery of the main body at the part that is gripped when writing, and a chuck that is normally open is housed inside the main body. A horizontal hole is passed through the main body at an opposing position between the chuck and the fastener, and a ball is loosely installed in each hole, and the fastener is moved forward or backward to remove the chuck from both sides. When the lead is pressed and held, the chang is made to bias each ball with weak elasticity, and the lead guide pipe with a lead holding member attached to lightly hold the lead inside the tip can be slid freely. A mechanical pencil that automatically dispenses refills stored in the holder.
