Abstract
An integral-type transaxle apparatus comprising a single housing in which a pair of driving axles, a differential mechanism for differentially connecting both said driving axles to each other, a driving hydraulic stepless transmission which fluidly connects a hydraulic pump and a hydraulic motor, a steering hydraulic stepless transmission which fluidly connects a hydraulic pump and a hydraulic motor, a mechanical transmission for transmitting outputs of both said hydraulic stepless transmissions to said differential mechanism are accommodated, wherein at least one of said hydraulic stepless transmissions is disposed such that a rotational axis of a pump shaft of said one hydraulic stepless transmission and a rotational axis of a motor shaft of said one hydraulic stepless transmission are perpendicular to each other.
