Claims

[Scope of utility model registration request]

A balance mechanism for attitude control connected to the left and right running wheels is provided with a lift control cylinder for moving the balance mechanism in parallel, and a rolling control cylinder for swinging the balance mechanism. In a paddy field work machine configured to perform simultaneous and contradictory lifting control, a swing sensing means attached to a balance mechanism is provided to detect swings of the balance mechanism that moves when the lifting control cylinder is operated on the lifting side of the machine body. and a rolling control mechanism that controls the operation of the rolling control cylinder are interlocked via a connecting means to operate the rolling control cylinder so that the left and right traveling wheels return parallel to the aircraft body based on the vibration sensing result. The apparatus for returning a machine body to a parallel posture in a paddy field working machine is also characterized in that the swing sensing means is disposed between the machine frame and the balance mechanism.
