Abstract

An in-pipe moving apparatus for passing through a pipe bent in any direction without control of the attitude of the apparatus is provided. The in-pipe moving apparatus may include at least three sets of tire-integrated wheel units arranged in series in a traveling direction and at least two sets of joint sections that pivotably link the at least three sets of tire-integrated wheel units to each other. Each of the at least three sets of tire-integrated wheel units includes a tire-integrated wheel, a drive section, a first frame fixed to the drive section, and at least one second frame pivotably attached to the drive section. A bending generator is provided between one of the first frames and one of the second frames in the at least three sets of tire-integrated wheel units and imparts tension for causing the first frames and the second frames to have a V-like bent shape.
