In a multistage speed change gear system including a plurality of gears selectively interconnecting an input shaft and an output shaft located parallel to one another, the gears disposed concentric with the input shaft are supported by ball-and-roller bearings supported by at least one stationary member which is an entity separate from the input shaft. By this arrangement, relative movements occur between inner and outer races of the ball-and-roller bearings when a rotational force is transmitted from the input shaft to the output shaft, thereby preventing or reducing the development of fretting corrosion in the ball-and-roller bearings. |
