Abstract

A hybrid vehicle includes an engine, a front module, a drive wheel, a transmission, a case, an oil inlet, a return passage, and a bypass passage. The case has a first chamber accommodating the front module, and a second chamber accommodating the transmission. The second chamber includes an oil pan. The oil inlet is arranged inside the oil pan. The return passage communicates the first chamber with the second chamber. The return passage keeps a first oil level inside the first chamber higher than a second oil level inside the oil pan by applying flow resistance to oil. The bypass passage is arranged at a position higher than the first oil level when the hybrid vehicle is in a horizontal position and lower than the first oil level when the hybrid vehicle is leaning forward at a predetermined angle.
