A guide bar (1) is provided for a portable handheld work apparatus, such as a motor-driven chain saw or overhead branch cutter, and includes an elongated, flat base body (4) having a peripherally extending guide groove for guiding a saw chain (6). In the region of the direction-changing section (14) at the free tip (13) of the guide bar (1), the saw chain (6) is laterally partially covered by guide discs (17, 18) which rotate with the idler sprocket (19). The guide discs (17, 18) include radially projecting sections (20, 20'). Corresponding radially projecting sections (20) of one guide disc (17) are arranged offset relative to the radially projecting sections (20') of the other guide disc (18). With this constructive measure, the manipulation of the portable handheld work apparatus is improved.
