Claims

[Scope of utility model registration request]

In a writing instrument equipped with a valve mechanism that controls the amount of ink supplied from the ink chamber to the pen tip, the end of the writing instrument can be adjusted by pressing a spring piece located on the side of the valve stem of the valve mechanism. The end of the spring body is elastically deformed so as to move in the axial direction, and the knocking force of the knock body, whose button part is exposed outside the side of the shaft cylinder, can be transmitted to the spring piece of the spring body. A writing instrument.
