Abstract
A frame structure for a working vehicle having crawler running devices includes main frames extending longitudinally along right and left sides of a vehicle body. The crawler running devices have track frames extending below and along the main frames, respectively. An oil tank is disposed between the main frames for rigidly interconnecting forward positions of the main frames and rigidly interconnecting the track frames. The frame structure includes an engine supporting frame for supporting an engine rearwardly of the oil tank. The engine supporting frame is connected to the oil tank through a reinforcing beam, and is curved downwardly with an intermediate portion thereof lying substantially level with the bottom of the oil tank.
