A driving module may include a driving source configured to generate power, a gear train that includes a decelerating gear set configured to receive driving power from the driving source and a ring gear attached to one side of the gear train, and a rotary joint that includes at least one planetary gear configured to rotate in response to power received from an output end of the decelerating gear set and to revolve along the ring gear. The driving module may include one or more noise reducing members configured to mitigate noise produced based on interaction between one or more elements of the driving module. The driving module may be included in a motion assistance apparatus, where the driving module drives a module that supports a portion of a user body.
