  "textContent": "Disclosed is a travel assembly for a dump truck, which facilitates to provide a flange 10f on an inner peripheral wall of a spindle 10 by casting. This flange 10f is adapted to arrange a support bearing 50 for supporting a shaft 13 at its portion located between a motor 8 and a reduction gear unit 14. The spindle 10 is formed of a chassis-side member 10c and a reduction gear unit-side member 10d joined together by welding (10e indicates a joint). The chassis-side member 10c is to be fixed on a chassis of the dump truck, and the reduction gear unit-side member 10d is located closer to a side of the reduction gear unit 14 than the chassis-side member 10c. The reduction gear unit-side member 10d is located on a side of an outer periphery of the portion of the shaft 13, where a distance to a coupling as a connected part between the motor 8 and the shaft 13 and a distance to a first sun gear 15a as a connected part between the reduction gear unit 14 and the shaft 13 are equal to each other. On an inner peripheral wall of the reduction gear unit-side member 10d, the flange 10f for the arrangement of the support bearing 50 has been formed together with the reduction gear unit-side member 10d by casting.",
