Abstract: In an inverted pendulum type vehicle no excessive load is exerted on a sub-wheel even in the case where some downward load is exerted on a sub-wheel arm. The inverted pendulum type vehicle includes a main wheel capable of moving forward, rearward, to the left and to the right with a vehicle body frame supported by the main wheel. The inverted pendulum type vehicle further includes the sub-wheel arm turnably supported on the vehicle body frame with the sub-wheel being supported by the sub-wheel arm and being grounded. The sub-wheel is supported through a deformable biasing device, and is biased into a predetermined position in relation to the sub-wheel arm. When a downward load is exerted on the sub-wheel arm, the biasing device deforms, whereby at least part of the sub-wheel arm is grounded.
