<P>PROBLEM TO BE SOLVED: To provide a caulking method in which deficiency of the fixing force of caulking is solved. <P>SOLUTION: The caulking method plastically deforms an end A of a caulking pin 4 penetrating through caulking holes 31, 32 formed concentrically in a plurality of members to fix the plurality of members. The caulking method includes: a first step of plastically deforming the end A so as to enlarge the diameter of an inner part B of the part in an axial direction of the caulking pin 4 other than the end A; and a second step of plastically deforming the outer periphery of the end A so as to enlarge the diameter of the end A larger than those of the caulking holes 31, 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
