摘要： A dual-pinion electric power steering device has: a rack shaft that causes a turnable member to turn; a first pinion shaft to which a steering force from a steering wheel is transmitted; a first rack teeth disposed on the rack shaft and capable of meshing with the first pinion shaft; a second pinion shaft to which a rotational driving force from an assist motor is transmitted; a second rack teeth disposed on the rack shaft and capable of meshing with the second pinion shaft; a first pressing member disposed across the rack shaft from the first pinion shaft and configured to press the rack shaft toward the first pinion shaft; and a second pressing member disposed across the rack shaft from the second pinion shaft and configured to press the rack shaft toward the second pinion shaft. The first pressing member has a lower rigidity than the second pressing member.
