To enable a bypass conveyer to be constituted by a single drive mechanism for energy saving to simplify the drive mechanism by constructing conveyer ends of the main conveyer and the sub-conveyer so as to be linked by a link means.
A link means T is constructed so that a link roller 12 comes into contact with a driven roller 6b or a driving roller 7a when the folded main conveyer body 1a and the sub-conveyer body 1b linearly connected with the connection part to horizontally oscillate in a state of using this bypass conveyer body 1. On the other hand, when the sub-conveyer body 1b oscillates, the driven roller 12 is at least separated from the sub-conveyer body 1b in a state of not using the bypass conveyer body 1. Because both conveyers 1a, 1b are connected linkable through the link means T, the bypass conveyer can be constituted of a single drive means for energy saving and simplifying the drive mechanism D.
