Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a compact conveyance bogie for a pipe body capable of being inserted into and pulled out of a pipe body easily. SOLUTION: An auxiliary wheel 8 which is moved vertically by a cylinder 7 and is made of urethane rubber is provided at a position closer to a front wheel 2 on a rear side than a front wheel 2 so that the front wheel 2 can leave and reach a rail 11 provided in an existing pipe on a front end side of a pipe body 1 in a condition in which the auxiliary wheel 8 comes into contact with an inner face on the front end side of the pipe body 1. The auxiliary wheel 8 runs in the pipe body 1 while the front wheel 2 floats from the inner face of the pipe body 1 so that a bogie can be easily inserted into and pulled out of the pipe body 1 without damaging the inner face of the pipe body 1.
