摘要： There is provided rolling element spacers that are used in a rolling guide device having an endless circulation path of balls and that are arranged to alternate with a multiplicity of balls and circulated in the endless circulation path along with the balls. They are constituted by a disc-shaped inner member having a pair of ball holding seats on which the balls slide in contact therewith and an annular outer member covering an outer circumferential surface of the inner member, and the outer member and inner member are molded from resin materials having different flexural modulo.

摘要： There is provided a rolling element spacer used in a rolling guide device having an endless circulation passage of balls, arranged alternately with many balls in the endless circulation passage, and circulating together with the balls in the endless circulation passage. It has a pair of ball holding seats each of which is formed in a concave spherical face form nearly approximating a spherical face of the ball and sliding-contacts with the ball and, around each ball holding seat, there is formed an annular dropout prevention portion protruding in a ball arranging direction than an edge portion of the ball holding seat and kept in non-contact with respect to the ball seated on the ball holding seat.

摘要： There is provided a rolling element spacer used in a rolling guide device having an endless circulation passage for balls, arranged alternately with many balls in the endless circulation passage, and circulating together with the balls in the endless circulation passage. In order to prevent the rolling element spacer from falling sideways and avoid a trouble such as malfunction of the rolling guide device, the rolling element spacer is formed such that its diagonal dimension in a thickness direction becomes larger than an inner diameter of the endless circulation passage.
