PROBLEM TO BE SOLVED: To provide a crawler type traveling vehicle which allows running on an upper surface side of a rising step without difficulty in a space part having a small vertical direction dimension and achieves the running-on without providing a driving mechanism such as a motor for rotation with an easy operation to run the vehicle on the upper surface side of the step part. SOLUTION: This crawler type traveling vehicle includes a front crawler 7 projecting forward in a front part of a main crawler 6 and a rear crawler 8 projecting backward in a rear part of the main crawler 6. The front crawler 7 is directed obliquely forwardly upwardly and is fixed in a rotation-inhibited state. The rear crawler 8 is prevented from rotating upward in a directed backward state and is made to rotate downward by self-weight from the directed backward state. The crawler type traveling vehicle may include a first stopper mechanism and a second stopper mechanism. COPYRIGHT: (C)2011,JPO&INPIT |
