PROBLEM TO BE SOLVED: To provide a translatory slide bearing in which a local abrasion in a slide part is prevented to lengthen life and the relative movement of a slider and a guide rail can be smoothly performed. SOLUTION: The translatory slide bearing comprises the long guide rail having a guide groove, the slider having a guiding groove opposed to the guide groove and a cylindrical guide pin provided in a space formed by the guide groove and the guiding groove. On at least a part of an outer peripheral surface in sliding contact with the inner peripheral surface of at least one of the guide groove and the guiding groove, the guide pin has a clearance groove recessed in section which is inclined to one direction with respect to the axis of the guide pin. The guide pin is internally provided in the space so as to be relatively movable in the longitudinal direction of the guide rail to at least one of the guide rail and the slider in sliding contact with the outer peripheral surface having the clearance groove.
