A crawler-type traveling body comprising:
- a crawler;
- a drive wheel including a drive shaft, the drive wheel configured to apply a driving force to the crawler;
- at least two track rollers disposed below the drive wheel, the crawler being stretched around the drive wheel and said at least two track rollers;
- an auxiliary mechanism between said at least two track rollers, the auxiliary mechanism includes:
- a swing shaft;
- a first auxiliary wheel;
- and
- a second auxiliary wheel, the first auxiliary wheel and the second auxiliary wheel being swingable around the swing shaft;
- and
- a tensioner coupled to the drive shaft of the drive wheel, the tensioner configured to press the drive wheel against the crawler to apply tension to the crawler,
- wherein a push-up amount of the first auxiliary wheel pushed up in a vertical direction is larger than a push-down amount of the second auxiliary wheel pushed down in the vertical direction in a swing movement of the auxiliary mechanism, and
- the drive wheel includes an in-wheel motor that transmits a rotative force to the drive wheel.
