HYPOID GEAR DEVICE AND FINAL REDUCTION GEAR FOR VEHICLE

摘要

A hypoid gear device and a final reduction gear for a vehicle. The drive pinion (12) of the final reduction gear (10) having a hypoid gear is formed of a gear having a cylindrical outline. A drive pinion shaft (16) is projected from both sides of the drive pinion (12), and the drive pinion is supported on bearings (18) and (20) at these both projected portions. Since the outline of the drive pinion is formed in a cylindrical shape, the drive pinion can adopt a center supporting structure. Thus, the deflection of the shaft can be suppressed and a bearing load can be lowered.
