Abstract

To provide a ball screw device and a steering device capable of securing smooth circulation of balls while suppressing occurrence of clogging of the balls caused by displacement in a radial direction between a deflector and a nut main body. A ball screw device includes a ball screw nut (70) and a circulation path (85). The ball screw nut (70) includes a nut main body (80) and a deflector (90). The deflector (90) includes an inclined portion (100) provided at a peripheral part of a connection portion (97) between a passage (94) and the circulation path (85) of the nut main body (80) for securing passing of the balls (51) at the connection portion (97) when an insertion position of the deflector (90) with respect to the deflector mounting hole (81) is displaced from a desired position within a range of a given distance.
