Deflectors (45b) of a nut (45) pick up balls (65) from a rolling passage (23b, 45f) in a tangential direction of the rolling passage and also in a direction of a lead angle thereof, and therefore the balls (65) can be picked up into a circulating passage (45c) without changing a direction of rolling of the balls, and therefore the smooth rolling can be secured, and operating sounds, vibrations, etc., can be kept to a low level.
