A drive unit of an electrically assisted bicycle includes a movement restrictor to restrict the movement of a first bearing relative to a housing along a thrust direction. A first end surface of the first bearing is farther outward than a second end surface along the right-left direction. The housing includes an abutting portion that abuts the first end surface of the first bearing, and a groove that is farther inward than the abutting portion along the right-left direction. The movement restrictor includes the abutting portion, the groove of the housing, and an elastic member fitted in the groove.
