In the drive device for an industrial vehicle, the drive pinion between the pair of bearings has an oil circulation hole drilled in the hole to communicate an upper chamber and a lower chamber, and lubricating oil injected into the lower chamber and the upper chamber. Since the drive device for an industrial vehicle has a protrusion on the outer periphery of the shaft that is inclined with respect to the axial direction,
Without major changes to the conventional structure, the bearing makes effective use of the extra space created on the outer circumference of the shaft of the drive pinion, and forces the circulation of lubricating oil between the upper and lower chambers of the carrier. This is done smoothly and by flowing between the rollers of the bearing that supports the drive pinion, so the drive pinion 1 built in the lower chamber is
0, the durability of the drive gear 12 and its bearings can be significantly improved. Furthermore, the lubricating oil is agitated by the projections provided on the outer periphery of the shaft of the drive pinion, and local temperature increases in the lubricating oil near the bearings are prevented, which, together with the circulation of the lubricating oil, Bearing durability is significantly improved.
