Summary:PROBLEM TO BE SOLVED: To solve a problem in a method using a plurality of simple HSTs in a case when the plurality of HSTs are used for a plurality of purposes, wherein input mechanisms from an engine, charge pumps, port blocks for piping, and the like are respectively mounted for each HST, and further oil returning structures are respectively mounted for each HST, which complicates a structure, increases the number of components, increases the cost, spends a wide installation space and complicates the mounting and demounting work. SOLUTION: In this multiple HST composed of the first HST at an input upstream side and the second HST at an input downstream side, sharing one port block, pumps P1, P2 of the first and second HSTs, motors M1, M2 of the first and second HSTs are arranged on one face of the port block PB in a state of being in parallel with each other, and both pump shafts PS1, PS2 are engaged with a gear.
