The present invention relates to a ball connecting body (1) in which a multiplicity of balls (3) are arranged in a line at a predetermined interval and in a freely rotating manner, and more particularly to a ball connecting body (1) installed and used in a ball endless track of a ball screw apparatus in which a screw shaft (10) and a nut member (20) are meshed with each other through a multiplicity of balls (3) and a ball screw apparatus using the same. The ball connecting body (1) is constituted by a multiplicity of balls (3) circulating on a substantially circular ring-like ball endless track provided in a bearing apparatus, and a flexible connecting body belt (2) arranging the balls (3) in a line at a predetermined interval and holding each of the balls in a freely rotating manner. Further, the connecting body belt (2) is constituted by a plurality of spacer portions (4) inserted between the mutually adjacent balls (3) and having a spherical seat (6) for bringing the balls into contact therewith, and a flange-like connecting band portion (5) mutually connecting the spacer portions (4) in such a manner as to outwardly surround the spacer portions, and is formed in a substantially circular ring shape at a time of arranging the balls. <IMAGE> |
