An endless linear motion roller bearing assembly includes a rail, a slider and a plurality of rollers interposed between the rail and the slider. The slider is provided with at least one endless circulation path which includes a load path section defined between the slider and the rail, a return path section and a pair of curved connecting path sections, each connecting the corresponding ends of the load and return path sections. The rollers roll along the endless circulation path back and forth to provide a limitless relative motion between the rail and the slider. Each of the curved connecting path section is typically semicircular in shape and its outer half wall surface is defined by a V-shaped guide plate of a thin steel plate. Preferably, the V-shaped guide plate is formed with a tongue at one end where the curved connecting path section is connected to the load path section to provide a smooth transition. In addition, the V-shaped guide plate is formed with a mating projection which projects outward from a surface of the end block to be fitted into a mating recess formed in a side cover plate to thereby provide a smooth transition between the curved connecting path section and the return path section.
