<P>PROBLEM TO BE SOLVED: To provide a return guide capable of reducing skew by making small the deviation and inclination in a rolling direction when a rolling element passes through a turnaround passage, and a linear guide bearing device provided with the same. <P>SOLUTION: A linear guide bearing device is provided with a guide rail 10, a slider 20 straddling the guide rail 10 so as to be relatively movable along the axial direction through the medium of rolling of a plurality of cylindrical rollers 30, and an end cap 40. On each of the cylindrical rollers 30, one or more grooves are formed along a circumferential direction. A return guide 50 forming a turnaround passage 70 is formed on the end cap 40 as a portion of the circulation passage of each of the cylindrical rollers 30. A projecting stripe loosely fit to the groove in each of the cylindrical rollers 30 is formed in the return guide 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
