In each slider, one ball rolling groove is formed in a lower portion of an inner surface of one of the side walls, and one ball rolling grooves is formed in an upper portion of an inner surface of the other of the side walls thereby to form the ball rolling grooves asymmetrically with respect to a vertical plane containing a longitudinal axis.
