Linear motion guide unit

A linear motion guide unit comprising:

• a track rail having a first rail raceway surface and a second rail raceway surface each extending in a longitudinal direction;
• a first slider relatively movably attached to the track rail, the first slider having a first slider raceway surface facing the first rail raceway surface and a planar first mounting surface provided with a first mounting hole for another member to be mounted;
• a second slider relatively movably attached to the track rail, the second slider having a second slider raceway surface facing the second rail raceway surface and a planar second mounting surface provided with a second mounting hole for another member to be mounted;
• a plurality of first rolling elements rolling on a first load-carrying race composed of the first rail raceway surface and the first slider raceway surface;
• and
• a plurality of second rolling elements rolling on a second load-carrying race composed of the second rail raceway surface and the second slider raceway surface;
• the first slider being provided spaced apart from the second slider as viewed in the longitudinal direction,
• the second mounting surface being inclined with respect to the first mounting surface as viewed in the longitudinal direction.
