Claim:
An inverted pendulum type vehicle, comprising: a vehicle body frame; a main wheel configured by combining a plurality of rotatable driven rollers such that axial lines of rotation of the driven rollers form a ring; left and right driving disks supported for rotation on the vehicle body frame so as to be positioned on the opposite left and right sides of the main wheel in a substantially coaxial relationship with an axial line of rotation of the main wheel and including a plurality of rotatable driving rollers disposed for contact in a twisted relationship with the driven rollers; a drive unit for driving the driving disks to rotate; an axle comprising a hollow shaft member for supporting the left and right driving disks for individual rotation in a positioned state in the axial direction; a respective fastening member for each of said driving disks, which engages with a threaded portion formed in the proximity of an end portion of the hollow shaft member and fixes the position of the corresponding driving disk in the axial direction; and a supporting shaft inserted in a central through-hole of the hollow shaft member and having an end portion projecting outwardly from the central through-hole and fixed to the vehicle body frame.
