Abstract
Operability, low noise characteristic and endurance are further improved at a reduced cost and easily by suppressing the fluctuation of a pitch between rolling elements due to the effects of swelling caused by oil and fats such as lubricants also in a case of using the elastomer for the material of the retaining piece. In a linear guide device in which a retaining piecemade of an elastomeric material is interposed between each of steel balls B adjacent with each other in the circulating direction, the concaved surfaceof the retaining pieceis in contact with the steel ball B adjacent with the retaining pieceat a position for 50% or less of the diameter of the steel ball B, and the rigidity value of the retaining pieceis defined at 0.053 N/μm or more and 0.175 N/μm or less.
