摘要： A flange member 20, which is formed as a separate body from a motor shaft 6, is screwed to an end 6a of the motor shaft 6. The flange member 20 functions as a flange 19 of the motor shaft 6. A flange 18, which is formed at an end 13a of a ball screw nut 13, is fastened to the flange 19 of the motor shaft 6. This couples the ball screw nut 13 to the motor shaft 6. A coupling member 27 is arranged in the joint portion between the ball screw nut 13 and the motor shaft 6. The coupling member 27 is formed by a tubular portion 28 and a plate flange 29, which extends radially outward from the outer circumferential surface of an end of the tubular portion 28. The tubular portion 28 of the coupling member 27 is fixed to the motor shaft 6, and the plate flange 29 is fixed to the flange member 20.

摘要： A fitting recess portion (18) that connects fitting holes (16,17) to each other is formed in a peripheral face (13s) of a ball screw nut (13). A circulation member (15) includes a pair of fitted portions (19, 20) that are fitted in the fitting holes (16, 17), and a connecting portion (21) that provides communication between the fitted portions (19, 20). A communication groove (23) that has an opening on the fitted end side of the connecting portion (21) and that extends in the axial direction is formed in the connecting portion (21). When the connecting portion (21) is fitted in the fitting recess portion (18) and the opening of the communication groove (23) formed in the connecting portion (21) is blocked by a bottom portion (25) of the fitting recess portion (18), a second path (L4) that forms a return path (L2) together with first paths (13) formed in the fitted portions (19, 20) is formed.

摘要： It is an object of the present invention to provide a ball screw apparatus wherein the ball screw apparatus includes a returning way (L2) by mounting a circulating member (15) in mounted holes (16,17) formed in the ball screw nut (13). The ball screw nut (13) includes a base portion (51) and an expanding portion (52). In the base portion (50) a distance from an axis center (O1) of the rack shaft (3) to a bottom portion (14a) of the nut side screw groove (14) is constant, and in the expanding portion (52) the distance is larger than that of the base portion (51). The expanding portion (52) includes a connecting area (34).

摘要： In an electric power steering system, a ball screw nut (23) of a ball screw device that drives a rack shaft is screwed to an axial end portion (6a) of a motor shaft (6) when a threaded portion (31) of a hollow threaded shaft (30) formed at an axial end portion (23 a) of the ball screw nut (23) is screwed to a threaded portion (32) formed in the inner periphery of a motor shaft (6). A flange member (33) that is larger in diameter than the ball screw nut (23) is fitted to the outer periphery of the axial end portion (6a) of the motor shaft (6). The flange member (33) is formed in such a manner that when the rotation of the flange member (33) is restricted, the rotation of the ball screw nut (23) and the motor shaft (6) in the same direction is restricted when the ball screw nut (23) is screwed to the motor shaft (6).
