Provided is a ball screw device in which a deflector can securely be prevented from falling into a nut when the deflector is attached. A ball screw device (40) includes a ball screw shaft (20), a nut (21), rolling elements (24), a ball recirculation path (R2), and a deflector (51). An attachment hole (41) has a pair of first faces (411a, 411b). The deflector (51) has a pair of second faces (511a, 511b) that respectively face the pair of first faces in a state in which the deflector is housed in the attachment hole. The first faces of the attachment hole and the second faces of the deflector have a locking structure in which the first faces and the second faces respectively lock each other in an improper state in which a part of the deflector is inserted into the attachment hole in a posture different from a posture of the deflector housed in the attachment hole.
