Abstract
A joining method of joining two pieces of subjects to be joined together, the subjects being a first member and a second member that has a joint insertion portion in which the first member is inserted, the method including: heating the second member that is set in an expansion restricting member and in which the first member is inserted to the joint insertion portion to first temperature to cause the second member to have thermal expansion and thereby causing the joint insertion portion to have plastic deformation in a direction in which a diameter shrinks with mechanically restricting thermal expansion of the second member by an inner surface of the expansion restricting member; and cooling the second member after the heating to join the first member and the second member together.
