PROBLEM TO BE SOLVED: To enable a smooth movement in a route containing a curved passage by providing a feeder in a relatively expanding/contracting part with a feed roller capable of abutting on a receiving surface of each receiving part from a side direction, the roller capable of abutting on both receiving surfaces formed on both connection members simultaneously from a side direction. SOLUTION: A feeding roller 68 is made close to and pressed against one of receiving surfaces 47 while the other surface 47 is abutted on a fixed roller 74, and a receiving part 46 is held by both rollers 68, 74. At this time, the roller 68 is driven to rotate by a rotation driver 65. Accordingly, through the press contact of the roller 68 forcibly rotated with the receiving surface 47, moving force is given to an endless continuous body by the rotation force, and thus the continuous body is moved at a required speed on a certain route. Also, the continuous body is relatively expanded and contracted when a pin 42 is moved to a slotted hole so that its movement at a curve is smoothly attained. |
