PROBLEM TO BE SOLVED: To provide a trailing carriage for a tunnel boring machine, the overall length of which is reduced. SOLUTION: In this trailing carriage for the tunnel boring machine, a plurality of connected carriage bodies 3a-3c, which are arranged in the rear of the tunnel boring machine a, are equipped with: hydraulic pumps 6x and 6y for supplying hydraulic pressure to various pieces of hydraulic equipment provided in the machine a, respectively; electric motors 7x and 7y for driving the hydraulic pumps 6x and 6y; a starting panel f for starting the electric motors 7x and 7y; control valves 8a-8e which are provided in a hydraulic circuit for connecting the hydraulic pumps 6x and 6y to the various pieces of hydraulic equipment; and an operating panel h for controlling the starting panel f. The operating panel h and the starting panel f are integrated together so as to serve as an operation starting panel 9; an operating panel part 9y and a starting panel part 9x, which constitute the operation starting panel 9, are connected together by means of an internal circuit 10; the operation starting panel 9 is mounted on the carriage body 3a; and a space for mounting the operation starting panel 9 on the carriage body 3a is made narrow.
