A travel assembly is provided with a cylindrical spindle for being fixed on a body of a working vehicle, a rotary shaft arranged extending in an axial direction through the spindle and rotationally drivable by a driving source, a rim rotatably arranged on a side of an outer periphery of the spindle to permit mounting of a wheel thereon, a planetary gear reduction mechanism for transmitting rotation of the rotary shaft to the rim at a reduced speed, a bearing rotatably supporting the rotary shaft via a sleeve integrally fitted on the rotary shaft, and a retainer holding the bearing in place. A lube oil pipe for feeding lube oil to the rotary shaft is held in place by the retainer. The lube oil pipe branches within the retainer to form an oil passage. The oil passage has an opening through which the lube oil can be fed to rolling elements in the bearing. |
