<p><P>PROBLEM TO BE SOLVED: To provide a fastening release method and a product disassembly device for safely easily and energy-savingly releasing a fastened state of a product of which the fastened state is released by heating. <P>SOLUTION: A product 1, of which heat fastening can be released, includes a base material 20 and a member 10 to be fastened which are fastened by a fastening tool provided in an inside of a recessed part 12 opening outward, recovering its shape by heating, and releasing the fastened state. An exothermic agent 52 is filled in the recessed part 12, and then a reaction agent 53, which heats the exothermic agent, is dispersed to heat the exothermic agent 52 so that the fastening tool is heated at a temperature for recovering its shape and the fastened state of the base material 20 and the member 10 to be fastened is released. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
