A linear guideway with synchronously operating spacers comprises a rail having a first rolling groove, a sliding block having a second rolling groove, a plurality of rolling elements disposed between the first and second rolling grooves, and a plurality of spacers. A receiving groove is formed in the second rolling groove and is located at the return portion of the sliding block for passage of the connecting portion of the spacers. The inner side of the receiving groove in the return portion has been deviated backward as compared to conventional structure, and the center of circle-arc of the receiving groove is deviated toward the sliding block.
