Abstract
In a linear motion guide unit, a raceway groove formed in a casing of a slider includes a first raceway surface extending along the length direction of the slider and a second raceway surface facing the first raceway surface and extending along the length direction of the slider. The second raceway surface includes a first portion including a center portion in a length direction of the casing, and a second portion including end portions in the length direction of the casing and having a wall surface shape different from a wall surface shape of the first portion. In the first portion, the first raceway surface and the second raceway surface define a symmetric Gothic arch groove, and in the second portion, the second raceway surface has a surface recessed from a position symmetric to the first raceway surface.
