| description | PROBLEM TO BE SOLVED: To provide a spacer manufacturing method for manufacturing a spacer precisely, simply, and at a low cost, the spacer being mounted in a spindle stock, so as to dispense with a bearing of a large size or a bearing of a special design in order to support unclamping force. SOLUTION: An inner-ring spacer 4 and an outer-ring spacer 5 have load receiving portions 4b, 5c which face each other in the axial direction through a clearance δ of a predetermined size, and are halved in splitting planes F1, F2 orthogonal to the axial direction and extending through the load receiving portions 4b, 5c. An inner-ring spacer splitting member 4A having the load receiving portion 4b and an outer-ring spacer splitting member 5A having the load receiving portion 5c are simultaneously worked to have equal axial widths. In addition, an inner-ring spacer splitting member 4B not having the load receiving portion 4b and an outer-ring spacer splitting member 5B not having the load receiving portion 5c are simultaneously worked to have equal axial widths, so that the axial width b of the latter is longer by the clearance δ than the axial width a of the former.
