Abstract: A cart-type transporting device includes left and right auxiliary rotating bodies moving in conjunction with left and right turning-section toothed wheels that guide a first endless chain; and a turning pathway section that protrudes at a position between the auxiliary rotating bodies, and that is provided with a lower protruding cam over which a transporting cart can pass. Left and right front-side projection shafts of the transporting cart engage with an engagement section of the respective auxiliary rotating bodies. Left and right rear-side projection shafts engage with an engagement section of the first endless chain. When the projection shafts are picked up by the rotation of the turning-section toothed wheels and the auxiliary rotating bodies, the lower protruding cam supports and guides a cam-following roller at a bottom section of the transporting cart in accordance with the same rotating pathway as the engagement section.

Abstract: A conveyance device has a drive route part wherein conveyance carriages travel at predetermined intervals, which is connected to a storage route part having a drive conveyer chain that supports the conveyance carriages for free travel. The drive route part has a drive conveyer chain including spaced carriage propulsion claw parts. The conveyance carriages have moved pins that horizontally extends in the left/right direction and which are freely detached/re-fitted in the up/down direction with the carriage propulsion claw parts. The conveyance device has a carriage-positioning mechanism which positions a conveyance carriage at a fixed position wherein the moved pin is positioned immediately before a guide ring for a corresponding one of the carriage propulsion claw parts, and has a carriage pushing-out mechanism which pushes out the conveyance carriage positioned at the fixed position, at a timing when the moved pin is fitted to the carriage propulsion claw part.
