PROBLEM TO BE SOLVED: To provide technology for increasing the axial width of an opposed face while maintaining high accuracy of the opposed face with respect to the shaft. SOLUTION: This bearing structure 50 movable in contact with the carriage guide shaft 155 has the opposed face 50a opposed to part of the side face of the carriage guide shaft 155 in a predetermined range in the axial direction of the carriage guide shaft 155 and put at least partly in contact with the side face. The bearing structure 50 has a plurality of partial bearing portions 51, 52. The opposed face 50a is formed in a cross section perpendicular to the axial direction by a plurality of partial opposed faces 51a, 52a of the plurality of partial bearing portions 51, 52.
