PURPOSE:To move a truck so smoothly, by making a sidewise moving attitude of the truck of a car type conveyor keepable right even on both straight and circular tracks, while coupling the truck an a driving chain together to be invariable in a horizontal position, and simplifying its coupling structure. CONSTITUTION:A truck 15 travels on a flat outer rail 18 and an inner rail 19 on tops of straight tacks 16a and 16b and a semicircular track 17 with flat rollers 20 and 21. A driving chain 22 paralleled with them is installed between these rails 18 and 19, and its attachement 23 is connected to a setting metal device 24 hangingly installed in this truck 15. This connected position should be on a base line 25. At this base line 25 and its front and rear parts, guide rollers 26, 27 and 28 adjoining to an inner surface of the inner rail 19 at these straight tracks 16a and 16b are pivotally supported on a lower surface of the truck 15 while guide rollers 29, 30 and 31 adjoining to an outer surface of the rail 19 at the semicircular track 17 are also pivotally installed, respectively. A guide plate 32 having plane sides 35a and 35b is set up in the outside of the inner rail 19 of the semicircular track 17, and a circular side 34 is formed in this guide plate 32.
