Abstract

An improved propelling pencil is provided of which lead can be projected or exposed to a predetermined amount by applying writing pressure to a pencil cyclinder, when the lead is worn out or broken. According to the invention, the pencil is free from breaking of the lead due to excessive projection of the lead from the pencil body.
