Abstract
A writing instrument comprises a barrel provided with a tip element at the front thereof, a writing mechanism provided longitudinally movably within the barrel, a resilient element for biasing the writing mechanism backward, a knock member detachably mounted on the rear end of the writing mechanism, and a rattle-preventive means provided between a knock member and the barrel. The rattle of the knock member can be completely eliminated despite the presence of a clearance between parts such as between the knock member and the barrel or the tail crown.
