To reduce the lateral dimension of a power unit by positioning an oil level gauge laterally inside, thereby making the power unit compact. A power unit P includes a hydraulic continuously variable transmission CVT, a transmission housing HSG for accommodating the hydraulic continuously variable transmission CVT, and an oil level gauge for checking an oil level in the housing HSG. The hydraulic continuously variable transmission CVT is configured by coaxially rotatably providing a fixed displacement type swash plate plunger pump P and a variable displacement type swash plate plunger motor M and connecting the plunger pump P and the plunger motor M through a hydraulic closed circuit. The outer circumference of a portion of a pump casing of the plunger pump P for supporting a pump swash plate member is reduced in diameter to form a reduced diameter portion. The oil level gauge is positioned so that a gauge portion extends near the outer circumference of the reduced diameter portion down to the bottom of the transmission housing HSG.
