<p>There is provided an in-wheel motor that can reduce the loss of energy. An electric vehicle driving device (10) includes a first motor (11), a second motor (12), a speed change mechanism (13), a speed reducing mechanism (40), and a clutch device (60). A first planetary gear mechanism (20) of the speed change mechanism (13) is a single-pinion type planetary gear device. A second planetary gear mechanism (30) of the speed change mechanism (13) is a double-pinion type planetary gear device. The electric vehicle driving device (10) operates so as to switch a first speed change state where the magnitudes of rotational forces of the first motor (11) and the second motor (12) are equal to each other and the directions of the rotational forces are opposite to each other, and a second speed change state where the rotational forces have the same magnitude and direction.</p> |
