1. A power transmission mechanism comprising:
a first motor;
a second motor;
a first input shaft to which power is transmitted from the first motor;
a second input shaft to which power is transmitted from the second motor;
a first output shaft to transmit power to a first driven portion;
a second output shaft to transmit power to a second driven portion;
a transmission mechanism which:
includes a planetary gear mechanism to receive power from the first input shaft and the second input shaft; and
is operable to send power from the first input shaft and the second input shaft to the first output shaft and the second output shaft; and
an interrupting mechanism operable to interrupt power transmission from the first output shaft to the first driven portion; wherein
the power transmission mechanism is configured such that power from the first input shaft and power from the second input shaft are introduced into the planetary gear mechanism which is a single planetary gear mechanism including a single sun gear and a single ring gear.
