PROBLEM TO BE SOLVED: To improve durability by suppressing pitching vibration and rolling vibration of an engine device and reducing the load charged on an engine supporting section or a body frame. SOLUTION: The center of gravity of the engine device and the height of a vibration proofing device for an engine are made the same. As a result, even when the pitching vibration and rolling vibration are apt to occur in the engine device in response to a travel of a working machine and a vertical operation of a working device, these vibrations can be suppressed, and the load charged on the engine supporting section or the body frame is reduced, thereby improving durability.
