摘要： A linear guiding device where noise characteristics are improved by reducing traveling noise and operability of a slider body is smoothed, and where movement braking can be improved by reducing rolling body passage vibration. Crowning 24 with a curved surface having a predetermined curvature radius R is provided on an end section of a rolling body raceway groove 11 of a bearing block 24. A crowning amount C of the crowning 24 is set to a value C>Hmax greater that the value of a maximum elastic deformation amount Hmax of a rolling body B elastically deformed in a rolling body rolling path 14 by a preload or an external load. By this, even when a large load acts on a bearing block 2A or a large installation error occurs by skewing etc., the rolling body B smoothly rolls without an elastic deformation amount of the rolling body B rolling on the end section side of the rolling body raceway groove 11 becoming greater than the crowning amount C. As a consequence, significant worsening of a noise level and impairment of operability can be prevented.
