Abstract
A writing instrument has a retraction mechanism of simple, inexpensive construction comprising a wheel (5) rotatably mounted on the barrel (1) and to which the trailing end of the writing unit (8) is connected by a pivot having its axis spaced from the rotation axis. In the writing position of the writing tip (9), the wheel abuts a stop defined either by the writing unit or the barrel to support the writing pressure exerted against the writing tip. The rear end of the reservoir tube (10) can be formed for direct snap-fit connection to the wheel, and the wheel is a snap-fit in the barrel.
