Abstract
A carriage moves along rail parts having straight portions and curved portions. The carriage has a pedestal section, and in the pedestal section, at least two first rotor parts and one or a pair of second rotor parts, which are located between the rail parts and which include a pair of wheels that rotate while in contact with side surfaces of the rail parts. The pair of wheels are attached to the pedestal section via support members. Support members of the first rotor parts are located in the pedestal section on predetermined reference lines that overlap center lines of the straight portions of the rail parts when the carriage is moving along the straight portions, and are rotatably connected to the pedestal section such that the rotational centers are positions off a line connecting the rotational centers of the pair of wheels.
