PURPOSE:To easily impress a seal and prevent a writing tip from rising and sinking due to knocking at the time of impression of the seal by arranging a knock mechanism at an inner hole in a back of a relay joint and arranging a writing body such as a ball-point pen in the front thereof so as to prevent the seal from moving axially due to pressure. CONSTITUTION:In a writing implement equipped with a seal having a writing body 23 such as a ball-point pen at the tip thereof and a seal 19 at the back, a knock mechanism equipped with a knock bar 4 and a slider 12 is arranged at an inner hole in a back of a relay joint 2. A holder 11 is fixed to the back of the relay joint 2 and the seal 19 is fixed to the back end of the holder 11. The slider 12 is externally mounted on the holder 11 in a manner movable only axially, connected to the knock mechanism in an interlocking manner, and a back axis 1 whose back end is blocked is detachably fixed to the outer periphery of the slider 12. A knocking stroke by which a writing tip 25 is to be retained in a rising and sinking state is set to be large, so that the knock mechanism operates at every impression of the seal so as to prevent the writing tip 25 from rising and sinking. |
