An article-turning / conveying apparatus provided with a mechanism for placing an article, traveling in a predetermined direction, and changing the direction of the article, wherein an endless roller chain provided on both sides of the conveyor frame has a constant pitch. An attachment pin is provided for each, a connection member having a connection shaft is mounted on the attachment pin to make the width direction constant, and a rotation shaft is rotatably supported substantially at the center of the connection member. A mounting table for articles is fixed to an upper end, one end of a swing lever is fixed to a lower end of the rotating shaft, a guide fitting is rotatably inserted at the other end of the swing lever, and a guide member is fixed to the conveyor frame. Is fixed in the traveling direction, and the guide bracket of the swing lever is engaged with the guide member, thereby enabling the mounting table of the article traveling integrally with the roller chain to be horizontally rotated, thereby being conveyed. Goods A device for changing the direction of an article. 2. An article-turning / conveying apparatus provided with a mechanism for placing an article, traveling in a predetermined direction, and changing the direction of the article, wherein an endless roller chain provided on both sides of the conveyor frame has a constant pitch. An attachment pin is provided for each, a connection member having a connection shaft is mounted on the attachment pin to make the width direction constant, and a rotation shaft is rotatably supported substantially at the center of the connection member.
