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.
