A joint structure of an annular member and a shaft member softer than the former is produced by (a) providing a shaft member with an oil spreading over its circumference, the shaft member having a plurality of discrete grooves, on its circumference in an inclined angular configuration about the axis of the shaft member, and (b) press fitting the annular member to the bore of the annular member with an interference such that the inner periphery of the annular member bore meshingly expands into the grooves. Press fitting proceeds under resilient deformation of the inner periphery of the annular member in the boundary friction state. A continuous oil film remains on the mating surfaces while securing firm joint.
