PROBLEM TO BE SOLVED: To provide a traveling bogie which can favorably secure the cooling efficiency of a radiator while making a manufacturing cost low.SOLUTION: A drive part support frame having a lattice window which is formed into a lattice frame shape is continuously arranged at a one-side front part of either of the left and right of a machine body frame in a state of being hung out to the outside of one side, a drive part is arranged on the drive part support frame. A cooling air duct which makes the one-side outside being the outside of a machine and a radiator communicate with each other in left and right directions is arranged at a lower part of a drive seat which is arranged at the drive part, cooling air can be supplied to the radiator from the outside of the machine via the cooling air duct, a bottom outside air take-in port is arranged at a bottom of the cooling air duct, and outside air being the cooling air can be taken into the cooling air duct from the bottom outside air take-in port via the lattice window of the drive part support frame.SELECTED DRAWING: Figure 10 |
