<P>PROBLEM TO BE SOLVED: To provide a pipe conveying carriage which is used for a pipeline laying method for forming a new pipeline inside an existing pipe etc. by inserting a pipe body, smaller in diameter than the existing pipe etc., into the buried existing pipe and a segment, in which a pipe supporting section for placing the pipe body is provided on a carriage traveling inside the existing pipe etc., which is provided with an alignment mechanism for aligning the pipe body with the existing pipe and the segment, and which facilitates the alignment of the pipe body in the case where there is a great difference between a bore diameter of the existing pipe etc. and that of the pipe body and where a gap is made between an inside-diameter surface of the existing pipe etc. and an outside-diameter surface of the pipe body. Ž<P>SOLUTION: In the alignment mechanism, a pantograph-type link mechanism 34 is ascendably/descendably provided below a table 31 with a supporting portion 32. A lifting/lowering device 30, which is composed of a hydraulic cylinder 35 for lifting/lowering the table 31 by lifting/lowering the link mechanism 34, is provided. The lifting/lowering device 30, which is installed on the carriage 11, lifts/lowers the table 31 via the link mechanism 34 by the hydraulic cylinder 35, so that the alignment of the pipe body 1 can be easily performed when the large gap is made between the existing pipe etc. and the pipe body.
