CRAWLER TYPE TRAVELING VEHICLE WITH FLIPPER FOR PASSING OVER STEP

PROBLEM TO BE SOLVED: To provide a crawler type traveling vehicle with front and rear flippers for passing over steps, capable of smoothly passing over steps without impacts, easily controllable and cost advantageous. SOLUTION: The rear flipper 4 is rotated from a normal state to slantly upward state by reaction force action of a downward step part with respect to the rear flipper 4 in the normal state, is rotated from the slantly upward state to the normal stated due to the deadweight action and/or restoration action of a spring, and is provided with a damper mechanism 4a for delaying these rotating operations. The rotation of the rear flipper 4 from the normal state to the slantly downward state can be regulated. COPYRIGHT: (C)2008,JPO&INPIT
