Abstract
In a writing instrument with a pressure mechanism for the movement of a writing element (4, 5, 6, 11, 12, 13) against spring pressure from a retracted position of rest into an advanced writing position, in which retention by means of a retention element (18, 19, 20) takes place, the retention element (18, 19, 20) has a cup section (18) open towards the rear. In this cup section is a ball (23) of magnetizable material which is axially freely movable back and forth in the cup section. Adjacent to the opening of the cup section (18) is a permanent magnet (16), the front face of which forms a concave contact surface (17), disposed coaxially to the writing element (4, 5, 6, 11, 12, 13) for the placement of the ball (23).
