Abstract: A writing instrument has a gripping tube rotatably fitted on a front portion of a barrel. At the front portion of the barrel, plural identifying marks having different identification characteristics, such as color, are disposed in parallel in a circumferential direction of the barrel. A window portion is provided in the gripping tube through which is visible an identifying mark selected by rotating the gripping tube relative to the barrel. When the user rotates the gripping tube to the position where the chosen color is visible through the window portion, a locking pawl on the barrel engages with a locking groove at the rear end of the gripping tube to lock the gripping tube in this position. Once locked in position, the gripping tube cannot accidentally rotate thereby preventing a change of colors appearing at the window portion even if the writing instrument is subjected to shock or vibration.
