1. A guide member of a traction mechanism drive for use on an internal combustion engine, comprising:
a one-piece guide member body having at least one through opening and a one-piece metallic sleeve inserted into the at least one through opening, the sleeve having a first end which, projecting out of the through opening, is arranged such that the first end can be brought into contact with an engine part, wherein the first end of the sleeve has a larger circumference than a second end, opposite the first end, the larger circumference at the first end forms a flange, at least an outer surface of the sleeve including the flange is of rotationally symmetric configuration, and the guide member body is configured so that the flange is arranged between the guide member and an underlying portion of the internal combustion engine and prevents the guide member body from contacting the underlying portion of the internal combustion engine, wherein the sleeve includes two circumferentially extending surfaces defining an encircling groove therebetween and the at least one through opening of the guide member body includes a projection that engages in the groove as a transportation lock, wherein the groove and projection are arranged and dimensioned so that the projection clips into the groove when the sleeve is introduced into the at least one through opening.
