PROBLEM TO BE SOLVED: To provide a joint method capable of reliably suppressing occurrence of a burr when joining different members consisting of metal members joined to each other, the metal member and a resin member, the resin members joined to each other, and the like to each other.SOLUTION: A clamp member 54 is disposed so as to be brought into contact with a top surface 1a of a first member 1 such that an inner portion of the clamp member 54 communicates with a through-hole 1c of the first member 1 while a protrusion 2c is being inserted into the through-hole 1c and a second member 2 is being disposed on an undersurface 1b of the first member 1. A rotary tool portion 51 is moved toward the protrusion 2c of the second member 2 inside the clamp member 54. The rotary tool portion 51 is caused to collide with the protrusion 2c, the protrusion 2c is deformed and an anchor portion 2ha causing the second member 2 to engage with the first member 1 is formed on an upper end portion of the protrusion 2c. |
