Abstract

A reducer 10 according to one embodiment comprises a first deceleration unit 100 and a second deceleration unit 200. The first deceleration unit 100 includes: a first carrier 101; a first case 102 that encloses the first carrier 101 and is retained so as to be capable of rotation relative to the first carrier 101; and a first deceleration unit 103 that is held in the first carrier 101 and includes a first center shaft 131 which corresponds to a first input unit and into which rotation is input from a driveshaft 303. The second deceleration unit 200 includes: a second carrier 201; a second case 202 that encloses the second carrier 201 and is retained so as to be capable of rotation relative to the second carrier 201; and a second deceleration unit 203 that is held in the second carrier 201 and includes a second center shaft 231 which corresponds to a second input unit and into which, along with the first center shaft 131, rotation is input from the driveshaft 303.
