摘要：A conventional retractable type writing instrument has problems of complexstructure of the mechanism for locking/unlocking the writing body, an increased number

of component parts, an difficulty in assembling operation and high cost of instrument.Further, since the conventional mechanism is incorporated in a rear part of a barrel, thebarrel must be increased in length to that extent. In the present invention, an operatingmember movable relative to an exterior body through operation is interlocked with arefill body having a nib at its tip, and an engagement portion for engaging an

engagement protrusion of an inner surface of a clip on the exterior body is formed onthe operating member. The engagement protrusion is engaged with the engagementportion to lock the nib of the refill body in a state of the nib projected from a tip of theexterior body. The locking of the nib in its projected position is released by an operationto be made in the same direction as the operation for locking the nib in its projectedposition. When the engagement protrusion and the engagement portion are to beengaged with or disengaged from each other by the operation, a relative movementbetween the engagement protrusion and the engagement portion at the time ofengagement or disengagement consists of a combination of a movement in a same planedirection and a movement towards or away from the plane.
