PROBLEM TO BE SOLVED: To provide an in-pipe traveling device capable of being traveled by advancing/retreating a member abutted on a wall surface of a conduit by a more simple mechanism and attaining reduction of manufacturing cost and miniaturization of the whole of the device. SOLUTION: The in-pipe traveling device is provided with a frame 7 arranged along an advancement direction A of the conduit; a shaft body 11 supported on the frame 7 so as to be laid in the advancement direction A; a pair of movable members 12, 13 provided on the shaft body 11 so as to be aligned in the advancement direction A and each independently advanceable/retreatable in the advancement direction A by transmitted drive force; and an abutment member 14 in which at least one is provided between the pair of movable members 12, 13 and which can press the wall surface of the conduit by being elastically curved according to a spaced distance L of the pair of movable members 12, 13 and being projected to a side S.
