PURPOSE: To lessen worker's burden as well as to lower cost by providing a carrying truck with a rotating stand which can take out a specified work out of a work loading means loading a plural number of works in a rectangularparallelopiped shape each where they are kept upright and are closely adhered, allows the work to be rotated by 90° while being suitably positioned for processing, and forwards the work to the following process.

CONSTITUTION: A carrying truck 3 is stopped in front of the row of transmission cases 5 to be processed or assembled. The transmission case 5 is pulled in over a rotating stand 4 so as to be loaded. When a piston rod 45 is extended to the direction K indicated by an arrow head with an air cylinder 42 operated, a bearing 40 is slid horizontally along a guide rail 41 so as to be moved, a support shaft 39 is supported by the bearing 40 so as to be rotated, and concurrently a L shaped rotating machine frame 38 is rotated by 90° to the direction I indicated by an arrow head with a pin 48 operated while being guided by a cam groove 49a, so that the transmission case 5 is turned out to be in a condition suitable for processing or assembling works where the longer direction is to be a bottom surface and the shorter direction is to be vertical. The carrying truck 3 is then moved to a carrying position for the following process.
