PURPOSE: A multi-type manihold is provided to prevent the tangle of pipes connected to an index table or a turn table by installing a rotational cylinder under the index table or the turn table. CONSTITUTION: Supplying channels(2,21,22,23,24,25) are formed on a rotational body(1) of a rotational cylinder installed on a lower portion of an index table or a turn table. A body(5) installed by up-and-down bearings(3,4) is installed within the rotational body(1). Plural channels(6,61,62,63,64,65) are formed on an external circumference of the body(5) and connected to respective pipes. Internal sides of the channels(6,61,62,63,64,65) are respectively connected to the supplying channels(2,21,22,23,24,25). A packing(7) for preventing an air leakage of the respective channels is installed among the respective channels. A fixing body(8) is fixed on a lower portion of the rotational body(1) and comprised of an air supplying channel(9) connected to the lower ends of the supplying channels.
