PCT No. PCT/JP96/01549 Sec. 371 Date Dec. 3, 1997 Sec. 102(e) Date Dec. 3, 1997 PCT Filed Jun. 7, 1996 PCT Pub. No. WO96/41977 PCT Pub. Date Dec. 27, 1996A hydro-mechanical transmission (2) with a simple construction and which can make full use of its advantages is provided. In a hydro-mechanical transmission in which a hydraulic power transmitting mechanism (10), having a hydraulic pump and a hydraulic motor, and a mechanical power transmitting mechanism (20), using gears, are switchably provided; the speed of input rotation is changed, and the resultant rotation is generated; the mechanical power transmitting mechanism has at least one planetary gear mechanism, and an output shaft (24) of the mechanical power transmitting mechanism is provided so that its output can be generated directly to the outside. The hydraulic pump (11) and the hydraulic motor (12) of the hydraulic power transmitting mechanism are of a variable displacement type. A directly-coupled clutch (30) is interposed between a motor output shaft (14) of the hydraulic power transmitting mechanism and the output shaft of the mechanical power transmitting mechanism.
