The ball screw includes a screw shaft, a nut body, rolling bodies, a synthetic-resin covering member, and a circulation member. The covering member has a tube shape arranged coaxially with the nut body to cover the outer peripheral surface of the nut body. A groove part formed on the inner peripheral surface of the covering member and the outer peripheral surface of the nut body form a rolling-body return path. The covering member is provided with an engagement part engaged with a cutout part formed on the outer peripheral surface of the circulation member.
