The present invention provides an inverted pendulum type vehicle which can perform a turning movement with ease without requiring any additional device even though the vehicle is configured to travel on a single drive wheel. A substantially vertical principal axis of inertia of the vehicle is tilted rearward with respect to a plumb vertical line. As result, when a rider shift his gravitational center in either lateral direction and tilts the vehicle in the corresponding direction, the main wheel is caused to turn around the principal axis of inertia so that the main wheel is steering in effect, and the vehicle can be turned in a desired direction.
