摘要： PROBLEM TO BE SOLVED: To provide a bearing structure of a transmission capable of shortening the axial direction dimension of the transmission and reducing the weight.
SOLUTION: The bearing structure of the transmission has a pinion fixed to the end of a counter-shaft and a plurality of speed change gears mounted on the counter-shaft, and includes a first single-row taper roller bearing installed between the pinion and a reverse driven gear as one speed change gear. Further the bearing structure includes a second single-row taper roller bearing installed as pinching reverse driven gear, and at least the first-speed driven gear, together with the first single-row taper roller bearing. This constitution allows shortening of the axial direction dimension of the transmission, and owing to adoption of single-row taper roller bearings, the load which the case bears is dispersed, and the transmission can be constructed light.

摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing device 1 for supporting a vehicle wheel having rolling elements 5a and 5b in double rows, allowing replacement of a bolt 8 for fixing the wheel easily and quickly.
SOLUTION: The rolling bearing device is structured so that the diameter of the rolling elements 5a arranged on the wheel side is smaller than that of the rolling elements 5b arranged on the counter-wheel side and the outside diameter on the flange part side of the outer ring 2 is made smaller according to the diametric difference. This enlarges the spacing between the bolt 8 mounted on the flange part 3b of an inner shaft member 7 and the peripheral surface of the outer ring 2.
