PROBLEM TO BE SOLVED: To set a running path having a curve with respect to a running-driven track dolly which runs in response to driving of driving means operatively coupled to a linear power-transmitting member provided along the running path. SOLUTION: A running motor 30 is mounted on a carrying vehicle 3 with a driving shaft of the running motor 30 facing downward. A running belt 6 is hung on a driving pulley 31 attached to the driving shaft such that the running belt 6 is guided by each pulley 32. The running belt 6 extends along a running path with both ends fixed to the floor. The carrier dolly 3 moves relative to the running belt 6 in response to driving of the running motor 30. The running belt 6 is contained in a recess of a guide rail, and longitudinally oriented so as to be bendable in the horizontal direction. In a curve of the running path, the running belt 6 abuts against an inner side-wall of the recess of the guide rail, such that the running belt 6 is guided along the curve.
