(Structure of the Invention) In order to achieve the above-mentioned object, the present invention is such that the elastic locking piece locks the knock rod at both forward and backward movements thereof. That is, the elastic locking piece locks the state in which the knock bar is advanced by the locking end at the lower end thereof, holds the state in which the writing portion is exposed, and in the state in which the writing portion is stored, the push button is pushed from the barrel. In the case of immersing, the locking portion provided near the lower end prevents the knock bar from advancing so that the writing portion is not exposed. Therefore, if the push button is arranged inside the clip, the push button is pushed by the clothing surface when the clip is clamped, and the engaging portion of the elastic engaging piece and the knock bar are engaged, so that even if an unexpected external force is applied to the knock bar. The knock bar does not move forward, and the writing part can prevent the clothes from being soiled and the core from being broken.
