The omni-directional drive device comprises a main wheel (2) comprising an endless annular member rotatable around a center of cross section perpendicular to a corresponding tangential line, electric motors (5R and 5L) for producing rotative forces around the rotation axis of the main wheel (2) and around the center of cross section perpendicular to a corresponding tangential line of the main wheel (2) and an arrangement (rotary members (4R and 4L) fitted with free rollers (3R and 3L)) for converting the rotational forces of the electric motors (5R and 5L) to the rotational forces around the rotation center of the main wheel (2) and around the center (C) of cross section perpendicular to a corresponding tangential line of the main wheel (2).

[Task] Provided is an omni-directional drive device that does not complicate the arrangement for a power source for a drive source such as an electric motor, and achieves a high durability and an ease of maintenance. [Solution] A drive force in a first direction is produced by a movement of a first moveable member (10) itself, and a drive force in a second direction is produced by the rotation of first free rollers (14) retained by the first moveable member, the rotation of the first free rollers (14) being caused by engagement with second free rollers (15) that are retained by a second moveable member (11) and rotative actuation of the second moveable member (11). Electric motors serving as drive sources may be mounted on base members (4 and 5).

An inverted moving body 1 includes: a riding part 2; a posture detection unit 6 that detects a rotation angle of the riding part 2 in a front-back direction; and a controller 8 that switches, when a switching condition is satisfied, a non-inverted control state to an inverted control state. The inverted moving body 1 includes a supporting part 5 capable of supporting the inverted moving body 1 in the inverted state while being in contact with the ground in the non-inverted control state. The switching condition includes a condition that an angle variation amount from the rotation angle of the riding part 2 in the front-back direction in a state in which the supporting part 5 is in contact with the ground is equal to or larger than a threshold.

Provided is an omni-wheel including an annular core member for rotatively supporting a plurality of free roller that is light, economical and strong. The omni-wheel comprises an annular core member (32) having at least one junction (A) defined by mutually circumferentially opposing ends (35) thereof, a plurality of sleeve members (36) defining an inner bore (38) and passed onto the core member and a free roller (60) rotatably supported on an outer surface of each sleeve member in a coaxial relationship, wherein the mutually opposing ends of the annular core member at each junction are fitted into either end of the inner bore of the corresponding sleeve member.

To suppress the height of a vehicle body frame of an inverted pendulum type vehicle in consideration of getting on and off the vehicle. Left and right drive units 7 are so disposed as to be juxtaposed in the left-right direction at same-height positions higher than a main wheel 3, and the left and right drive units 7 and a battery pack 9 are so disposed as to be juxtaposed in front and behind of a vehicle body frame 2.
