Abstract

When an insertion force of a rotary tool 340 has searched, it is made clearly that the force at the insertion initial time is large and when a friction stir joining is an ordinary operation time, the force becomes small. According, it is preferable to make small the insertion force at the insertion initial time. To members 20, 30 to be subjected to a joining at a position where the friction stir joining starts a hole 50 is opened, and this hole 50 after the rotary tool 340 has inserted, since a move of the rotary tool 340 is made to begin, a lowering of the insertion force can be attained.
