Abstract: A ball-point pen having simple operating and holding mechanism for ink tube including a ball-point and being capable of retracting and extruding the ball-point with a simple action of turning ball-point tip end of the pen up and down is provided. The ink tube has at its inner end opposite to the ball-point a magnetizable lid and around its body a weight freely slidable between said inner end and a projection provided adjacent the ball-point tip end, while holder tube of the pen has a magnetic member secured adjacent an end facing said lid of the ink tube for magnetically holding said lid and the ink tube when the ball-point is retracted, and a stepped part for locking the lid's end when the ball-point is extruded. When the tip end of the pen is turned down, the weight strikes the projection to separate the lid and hence the ink tube from the magnetic member and, when the tip end is turned up, the weight urges the lid's end to be unlocked from the stepped part.
