A traveling direction state detection device includes: a first distance sensor installed near a front side of the wheels in a traveling direction and configured to linearly measure a distance to a first linear position perpendicular to the traveling direction, the first linear position existing on the traveling surface diagonally downward in the traveling direction; a second distance sensor configured to linearly measure a distance to a second linear position perpendicular to the traveling direction, the second linear position existing on a traveling surface behind the traveling surface diagonally downward in the traveling direction, and ahead of ground contact points of the wheels; and a detector configured to detect a step, an inclination and an opening of the traveling surface based on an amount of change in the distances continuously measured by each of the first distance sensor and the second distance sensor at certain time intervals.
