摘要:
An automatic pencil which comprises a pointed end cap made of a synthetic resin material into which a lead pushing-out mechanism consisting of a lead chuck fixed to a lead container, a chuck ring externally fitted onto the lead chuck and a spring is inserted, a cushion stopper on the outer periphery of which and at one end thereof engaging projections are integrally formed so as to oppose to a plurality of engaging holes circumferentially provided around an open edge of the pointed end cap, and an outer tube into which the outer periphery of the backward end of the aforesaid pointed end cap is inserted to combine them with each other and, as a consequence, the resultant automatic pencil has a simple construction, so that it can easily be assembled.
