To provide a drive unit having a plurality of electric motors.SOLUTION: A drive unit 10 comprises a first electric motor for supplying rotational force to a sun gear 15 of a planetary gear mechanism 14; a second electric motor for supplying rotational force to an internal gear 17 of the planetary gear mechanism 14; and an output section 13 that receives rotational force from a carrier 18 of the planetary gear mechanism 14 and outputs rotational force. By virtue of this, when the first electric motor and the second electric motor are simultaneously rotated, rotational force of the first electric motor and rotational force of the second electric motor are output in combination from the output section 13 while a difference between the rotating speed of the first electric motor and the rotating speed of the second electric motor is absorbed. Accordingly, without using an expensive motor control unit, a reclining device can be actuated at a high speed in the event of emergency, for example.SELECTED DRAWING: Figure 4

    【課題】 複数の電動モータを備える駆動装置を提供する。【解決手段】 駆動装置10は、遊星歯車機構14の太陽歯車15に回転力を供給するための第1電動モータと、遊星歯車機構14の内歯歯車17に回転力を供給するための第2電動モータと、遊星歯車機構14のキャリア18から回転力を受けて回転力を出力する出力部13とを備える。これにより、第1電動モータと第2電動モータとが同時に回転したとき、第1電動モータの回転速と第2電動モータの回転速との差が吸収されながら、第1電動モータの回転力と第2電動モータの回転力とが合わさって出力部13から出力される。したがって、高価なモータ制御部を用いることなく、例えば緊急時にリクライニング装置を高速作動させることが可能となり得る。【選択図】 図4
