Abstract
A power unit includes an engine and a static hydraulic continuously variable transmission with a swash plate type hydraulic pump and a hydraulic motor, which are connected via a hydraulic pressure closing circuit. This power unit drives the hydraulic pump to rotate with the engine and performs swash plate angle control of the hydraulic motor. A crankshaft mechanism of the engine and a rotating mechanism of the static hydraulic continuously variable transmission are housed in a transmission housing. A cylinder of the engine is integrated with the transmission housing, and a swash plate control motor for swash plate angle control of the hydraulic motor is positioned at an area adjacent a root of the cylinder in the transmission housing.
