A traveling device (11) is provided with an electric motor (16) provided in a vehicle body (2) of a dump truck (1), an output shaft (17) an axial base end of which is connected to the electric motor (16) and which outputs rotation of the electric motor (16), a bottomed hole spline (53) formed in an axial front end of the output shaft (17), and an input shaft (42) which has a shaft spline (54) spline-coupled to the hole spline (53), and inputs the rotation of the output shaft (17) to a reduction gear mechanism (27). The output shaft (17) is provided with an oil reservoir space (55) formed in the innermost part of the hole spline (53), an annular oil groove (56) and an oil path (57) providing communication between the oil reservoir space (55) and the annual oil groove (56). Lubricant oil (100) supplied to the annular oil groove (56) is supplied via the oil path (57) to the oil reservoir space (55), and is supplied to a spline joint between the hole spline (53) and the shaft spline (54) with rotation of the output shaft (17).
