Abstract:
To prevent the positional precision of the ball return passage and the tongue of the end deflector relative to the nut main body from being impaired by an axial force applied by a screw used for securing the end deflector to the nut main body, the end deflector includes a flange ( 32 ) provided at an axial end of a main part ( 30 ) of the end deflector and provided with an axial through hole ( 50 ) for receiving a screw which is threaded into the nut main body, and a rib ( 52 ) projecting from a radially inner edge of the flange to an inner side of the deflector receiving recess ( 26 ).

Claim (Index 1):
A ball screw, comprising:\n a screw shaft having an outer circumferential surface formed with a shaft thread; a nut main body having an inner circumferential surface formed with a nut thread opposite to the shaft thread to define a rolling passage in cooperation with the shaft thread, a ball return passage extending in an axial direction, and a deflector receiving recess formed on at least one end surface of the nut main body in continuation with the nut thread and defining an open end of the ball return passage; a plurality of balls received in the rolling passage and the ball return passage; and an end deflector received in the deflector receiving recess; wherein the end deflector includes a main part provided with a ball passing passage for passing the balls between the rolling passage and the ball return passage, and a tongue guiding the balls from the rolling passage to the ball passing passage, a flange provided at an axial end of the main part and provided with an axial through hole for receiving a screw which is threaded into the nut main body to secure the end deflector to the nut main body, and a rib projecting from a radially inner edge of the flange to an inner side of the deflector receiving recess.
