PURPOSE: To reduce a load to be applied to a crank shaft while sufficiently evening the stress field to be generated by the interference fit. CONSTITUTION: A radial directional space R between interference fit surfaces 14, 15 depends on an axial directional space (x) in relation to the center line 12 of an interference fit part 10 in the axial direction, and the space R is changed in response to the exponential function f(x)=a.e<b> .<x> . At this stage, (a) and (b) mean a constant capable of being previously set, (x) means a space in the axial direction, f(x) means a space R in the radial direction. |
