A friction-drive carriage type conveyor includes a carriage 1 for running in a running direction along a horizontal track including a first track section and a second track section, which crosses a passage 26. Friction drivers 29 and 30 are fitted on both sides of the passage 26 to drive the carriage 1 across it. A main guide rail 14 lies along the whole length of the first track section. A rear auxiliary guide rail 31 lies along the first track section and is upstream of the passage 26. A front auxiliary guide rail 32 lies along the first track section and is downward of the passage 26. The carriage 1 is fitted with a pair of main guided members 4 and 5 for engaging with the main guide rail 14, a pair of front auxiliary guided members 6 and 7 for engaging with the front auxiliary guide rail 32, and a pair of rear auxiliary guided members 8 and 9 for engaging with the rear auxiliary guide rail 31. The main guided members 4 and 5 are spaced from each other in the running direction. The front auxiliary guided members 6 and 7 are forward of the main guided members 4 and 5 and spaced from each other in the running direction. The rear auxiliary guided members 8 and 9 are backward of the main guided members 4 and 5 and spaced from each other in the running direction. The auxiliary guided members 6 - 9 are positioned on either side of the main guide rail 14. While the carriage 1 is passing across the passage 26, at least two of the guided members 4 - 9 engage with the associated guide rail or rails 14, 31 and/or 32 on one or both sides of this passage. This ensures that the carriage 1 passes linearly across the passage 26.
