Abstract
A slide body () is arranged in a cut-away portion of a holder () under a clip () so as to not hinder writing or portability, and a safety mechanism is constituted so as to be engaged with the clip (). Due to functions of a knock rod cam () of a knock rod () and a knock cam () of a rotor (), further, the rotor () is rotated and moved forward responsive to each knocking operation, a refill () is brought to a writing position and a holding position alternately responsive to each knocking operation due to a cam mechanism provided in the inner wall of an inner cylinder () and a reactive force of a spring (). A slide body cam () provided on the slide body () is incorporated in a portion of the cam mechanism so that the knock type writing instrument thrusts the pen point out, by one knock even after the safety operation.
