ABSTRACT:
A device for supporting and sealing a final drive shaft bearing in a speed change gear having a construction in which a final drive shaft is supported by a bearing holder via a rolling element bearing and the bearing holder is fitted and fixed to a gear box. A stopper flange is formed at the inner end portion of the bearing holder and a first nut is screwed to the outer end portion of the bearing holder so as to clamp the outer race of the rolling element bearing in cooperation with the stopper flange. A seal housing is integrally formed with the bearing holder and extends outside the nut. An oil seal is fitted to the seal housing and has a seal lip that comes into contact with the outer circumferential surface of the drive shaft. The final drive shaft is equipped with a helical bevel gear and the rolling element bearing consists of a double-row angular contact type bearing. A second nut for clamping the inner race of the bearing in cooperation with the bevel gear is screwed to the final drive shaft.
