摘要： A shift fork support structure in a manual transmission of such a type that a shift fork is axially slidable on a fork shaft comprising a bushing press-fitted into apertures formed on the shift fork and engaging the fork shaft. The inner peripheral surface of the bushing is coated by Teflon layer. With this structure, the frictional resistance between the shift fork and the fork shaft may be reduced, thus permitting the shift fork to be smoothly operated.
