Abstract:
[Problem] To improve the travelling functionality of a travelling device equipped with dual, rotating, negative-pressure suction seals. [Solution] Provided is a travelling device equipped with dual, rotating, negative-pressure suction seals, which is characterised in that: a single, rotating, negative-pressure suction seal is respectively provided to the left and the right of the axis of travel of the travelling device; the distance between the rotational axis of one of the negative-pressure suction seals and the axis of travel is substantially equal to the distance between the rotational axis of the other negative-pressure suction seal and the axis of travel; the outer peripheral shape of each negative-pressure suction seal forms a shape comprising a farthest outer peripheral end portion, which is the outer peripheral end portion farthest from the rotational axis, and a nearest outer peripheral end portion, which is the outer peripheral end portion nearest to the rotational axis; and a driven wheel is provided inside each negative-pressure suction seal.
