<P>PROBLEM TO BE SOLVED: To obtain a heat sealing device that can suppress disconnection caused by thermal expansion of a heater. <P>SOLUTION: Shafts 50, 52 mounted on a base plate 15 of a heater side seal member 14 are inserted in through-holes 42, 44 of a terminal block 36 to which a terminal 32 of a ribbon heater 30 is fixed. The terminal block 36 is movable along the shafts 50, 52. Therefore, when the ribbon heater 30 contracts by thermal expansion, the terminal block 36 moves in the contracting direction of the ribbon heater 30 along the shafts 50, 52. As a result, a load received by the ribbon heater 30 during contraction can be reduced compared to a structure in which the heater shrinks against biasing force of "a spring", disconnection caused by thermal expansion of the ribbon heater 30 can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
