BALL SCREW MECHANISM

PROBLEM TO BE SOLVED: To provide a ball screw mechanism for inexpensively and reliably fixing a circulation member to a nut. SOLUTION: A fixing member 50 is located at one end of a T-groove 22 of the nut 20 and slid to the axial direction of the nut 20 with engaging portions 53, 53 engaging with a r...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ball screw mechanism for inexpensively and reliably fixing a circulation member to a nut. SOLUTION: A fixing member 50 is located at one end of a T-groove 22 of the nut 20 and slid to the axial direction of the nut 20 with engaging portions 53, 53 engaging with a radially inward portion 22a. Thereby, the fixing member 50 is slidably moved on the upper face of a top 40 and arrives at a center position, as shown in Fig.1. In this condition, the movement of the engaging portions 53, 53 outward in the radial direction is prevented by the radially outward portion 22b having a smaller width and slopes 51, 51 of the fixing member 50 thrust the upper face of a base 41 of the top 40, therefore preventing the come-off of the top 40 from the nut 20.
