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
【課題】製造コストを安価にして、ラジエータの冷却効率を良好に確保することができる走行台車を提供すること。【解決手段】機体フレームの左右いずれか一側前部に、格子枠状に形成して格子窓を有する運転部支持フレームを一側外方へ張り出し状に連設して、運転部支持フレーム上に運転部を配設し、運転部に設けた運転席の下方には、機外である一側外方とラジエータとを左右方向に連通する冷却風ダクトを配設して、冷却風ダクトを通して機外からラジエータに冷却風を供給可能とするとともに、冷却風ダクトの底部には底部外気取入口を設けて、運転部支持フレームの格子窓を通して底部外気取入口から冷却風ダクト内に冷却風となる外気を取り入れ可能とした。【選択図】図10
