PURPOSE:To erase a shortage of lubricant due to clawing by the inclination of a moving body and delete the catching of its edge during motion by providing a carrier at the mid-part of a bearing hole in parallel with an axial center and inclining both ends of the carrier. CONSTITUTION:A plastic linear plain bearing 1 is cylindrically formed with its peripheral surface 11 fitted to and held by a supporter and a circular hole 12 serving as a bearing hole forming the bearing surface which is in sliding contact with the peripheral surface 21 of an axis 2 via a lubricant at the position of an axial center. The circular hole 12 has a cylinder surface 13 serving as a carrier parallel to the axial center at the mid-part and an inclining face 14 of curvature at both ends, continuous smoothly to the cylinder surface 13. |
