ABSTRACT:
An ink conducting core for supplying ink from an ink container to a pen point is formed with an exposing recess in the vicinity of a connecting portion of the ink conducting core with a middle core. With this, even when outside impact etc. causes air bubbles to enter the ink conducting core, the bubbles may be ejected readily through the exposing recess whereby smooth ink supply can be secured all the time. An annular groove and a small diameter portion is provided in the rear part of an ink conducting core. An ink retainer having a through-hole through which the ink conducting core is fitted is constructed such that the through-hole has a small diameter portion in the rear end thereof. The ink conducting core is fitted to the ink retainer with the side walls of the annular groove engaging the small diameter portion in the rear end of the through-hole. As a result, it is possible to securely restrict back-and-forth movement of the ink conducting core due to impact etc.
