PROBLEM TO BE SOLVED: To provide a rolling screw device capable of restraining damage such as fracture from occurring relatively early in a tongue of an end deflector. SOLUTION: The front portion 20a of the tongue 20 with which a ball 13 as a rolling body collides is chamfered into a circular arc shape, thus increasing a contact area between the front portion 20a of the tongue 20 and the ball 13.
