Zusammenfassung:	To provide a traveling device for a dump truck that can stably suck and circulate a lubricant even during a stop of a vehicle and also during a high speed operation, and improve cooling and lubricating performance for the entire device.SOLUTION: A second carrier 38 used in a planetary gear reduction mechanism 33 on the last stage is fitted to an opening side of a spindle 14 in a non-rotation state. The second carrier 38 is provided with an oil passage 53 that sucks a lubricant 100 in a wheel fitting cylinder 18 and circulates it into a suction conduit 46. The oil passage 53 is constituted of: a first passage part 53A extended vertically (i.e., radially) downward within a support plate 38A of the second carrier 38; and a second passage part 53B axially extended in a coupling part 38C of the second carrier 38 from a lower-end side portion of the first passage part 53A and serving as an inflow end 53C opening in the wheel fitting cylinder 18 between the first planetary gear reduction mechanism 25 and itself.SELECTED DRAWING: Figure 3 【課題】車両の停車中でも高速運転時でも潤滑油の吸込み、循環を安定して行うことができ、装置全体の冷却、潤滑性能を向上することができるようにする。【解決手段】最終段の遊星歯車減速機構３３に用いる第２のキャリア３８を、スピンドル１４の開口側に非回転状態で取付け、第２のキャリア３８には、車輪取付筒１８内の潤滑油１００を吸込み、吸込管路４６内へと流通させる油通路５３を設けている。油通路５３は、第２のキャリア３８の支持板３８Ａ内を上，下方向（即ち、径方向）の下側へと延びた第１通路部５３Ａと、該第１通路部５３Ａの下端側部位から第２のキャリア３８の連結部３８Ｃ内を軸方向に延び第１の遊星歯車減速機構２５との間で車輪取付筒１８内に開口する流入端５３Ｃとなった第２通路部５３Ｂとにより構成されている。【選択図】図３
