The chain guide is configured to guide a chain. The link mechanism movably couples the chain guide to the base member between a retracted position and an extended position in response to movement of an operation cable. The cable guiding structure has one of bore, recess and groove formed on the link mechanism to guide the operation cable. The operation cable exits forwardly from the cable guiding structure within a sector having an angle of 150 degrees around the crank axis from an upper radius lying in a first plane that is perpendicular to a second plane containing a crank axis and a rear wheel axis.
