Abstract: A retractable writing instrument that includes a barrel, a writing tip, an actuating mechanism that includes a plurality of parts for extending and retracting the writing tip upon actuation of the actuation member, and a cushioning device enabling a retraction of the writing tip when an excessive pressure is exerted by a user. The cushioning device includes a spring member elastically deformable, which is integrally formed with a movable part of the actuating mechanism, the part being movable relative to the barrel. The spring member has a free end abutting the barrel toward its rear end and has a through hole. A stem extends within the spring member's hole and connects the actuating member to the actuating mechanism.
