Abstract

A driving device includes a first accommodating chamber (200), a second accommodating chamber (300), a partition wall (190) between the first accommodating chamber (200) and the second accommodating chamber (300), and a through-hole (191) formed in the partition wall (190). A speed reduction mechanism (40) includes a rotary shaft (44) extending from the first accommodating chamber (200) to the second accommodating chamber (300) through the through-hole (191), a first reduction gear (41) that is a hypoid gear, and a second reduction gear (42). The first accommodating chamber (200) accommodates a hypoid pinion (31) and the first reduction gear (41), and contains a first oil. The second accommodating chamber (300) accommodates a second motor-generator (50) and contains a second oil having a lower viscosity than the first oil. An oil seal (105) provides sealing between the rotary shaft (44) and the through-hole (191).
