PROBLEM TO BE SOLVED: To simplify the structure at a low cost and ensure easy maintenance services and further prevent a fabrication failure from being generated while shortening time for thermal caulking and saving energy consumption. SOLUTION: A regenerative block 2 incorporating a cartridge heater 1 and an indenting tool 4 for caulking to which heat is conducted from the block 2, are constitutionally arranged in such a way that both block 2 and tool 4 are relatively movable in a direction X where a pressurizing force is applied to a work 3 while a state in which heat can be conducted between the block 2 and the tool 4 is maintained. At the same time, a compression coil spring 7 for urging the indenting tool 4 by moving it in the direction where the pressurizing force is applied, is interposed between the indenting tool 4 and the regenerative block 2. Further, an air blower 8 capable of blowing cooling air only to the indenting tool 4 is provided. |
