PURPOSE:To always stably circulate a cargo carrier, by using a swing guide bar to prevent a support pin and a guide bar from interfering with each other. CONSTITUTION:A swing guide bar 47 is supported with a support shaft 50 on a bracket 49 and a guide bar supporter 48 on a conveyor fame so that the guide bar can swing. The support pin 43 of a pallet 41 normally moves from a guide bar 45 to the swing guide bar 47. When the pin 43 has come to a compressed spring 51, the spring is compressed by the weight of the pallet 41 so that the part of the swing guide bar 47 opposite the spring is quickly moved up. Another support pin 42 which succeeds and is engaged with a procket 52b passes through a space M made between the end of the guide bar 45 and the left-hand end 47b of the swing guide bar 47 as a result of its quick upward motion. For that reason, the support pin 42 moves forth without being hindered by the guide bar 45. |
