The invention is directed to a guide bar for a motor-driven chain saw (1) and includes a longitudinally extending flat base body (2) having a peripherally extending guide groove (3) for guiding a saw chain (4). In the region of the direction-changing section (12) of the guide bar (13), the saw chain (4) is partially laterally covered by guide discs (14, 14'), which rotate along with the idler sprocket (16). The guide discs (14, 14') include radially projecting sections (18) whose number is identical with the number of the teeth (17) of the idler sprocket (16). The tendency to kickback of the motor-driven chain saw is reduced with these constructive measures.
