To provide a traveling device in which a turning property of a traveling device is not deteriorated by braking pressure at the time of gentle turning.

This vehicle comprises a differential gear mechanism 6 having a pair of right and left side clutches 44R, 44L and a pair of right and left side gears 55R, 55L for transmitting a power obtained through changing the speed of a drive force from an engine to any one or both of wheel shafts 11L, 11R for driving a pair of traveling crawlers 3, 3; a switch means 104 capable of switching a brake turning mode for making the crawler 3 on the turning inside at the time of turning a vehicle having a turning clutch 82 controlling the differential gear mechanism 6 at the time of turning and transmitting the power to the traveling crawler 3 on the turning inside into a zero rotation and a gentle turning mode for making rotation of the crawler 3 on the turning inside lower than the crawler 3 on the turning outside; and a steering lever adjusting a clutch pressure of a turning clutch 82 according to an inclination degree. The clutch pressure when the steering lever 21 is placed at a maximum inclined position in the gentle turning mode is made equal to the clutch pressure when the steering lever 21 is placed at the maximum inclined position at the brake turning mode.
