Abstract
A linear motion rolling guide unit in which the ball retaining capability of retainer bands for retaining balls is improved by increasing the holding area and rigidity thereof. Each of the retainer bands extends along the relative raceway groove in a casing, and is fitted in a non-contacting state, i.e., loosely in the relative retainer band fitting groove formed along a raceway groove in a side surface of a track rail, the retainer band being formed so that both of longitudinal corner portions thereof which continue from the ball retaining surface thereof have an acute angle. The width of the ball retaining ball-opposed surface of the retainer band is set larger than that of a rear surface thereof which is on the opposite side of the ball retaining surface, i.e., the retainer band is formed to a substantially trapezoidal cross-sectional shape.
