[0094] Although the nichrome fine wire 3 which is stretched between the front substrate 3 ₁ of the protrusion 3 ₇ and the protrusion 3 ₈ of the rear substrate 3 _second heater cartridge 3 produces a extends linear expansion in the heat generated by energization, Figure 12 - Figure 13 about the pin 3 ₁₅ by a metal plate spring 2h as the substrate 3 ₂ tension given whenever means after due to its extended
A protrusion 3 which is turned clockwise and stretches a thin nichrome wire 3
Since ₇ and the interval between the projections 3 ₈ extends content of nichrome fine wire 3a (slack) is absorbed open, nichrome fine wire 3a is always maintained in tension (Figure 13).

When the thin nichrome wire 3a is broken, the lever 1i for removing the heater cartridge is moved to the position shown in FIG.
When the fingertip is rotated clockwise around the column 1k against the coil spring 1p as shown in the above, the tip side of the mounted heater cartridge 3 is pressed by the pivoted lever 1i, and the rear substrate 3 ₂ Rear end (knob)
From the front end side between 3 ₂₀ a comb tooth plate portion 1a · 1a protrudes outwardly.

[0096] Therefore the heater cartridge 3 Remove removed disconnect from between the left and right comb plate portion 1a · 1a by pulling in the opposite direction to the time of mounting the outer knob 3 ₂₀ protruding pinching with fingers, A new heater cartridge 3 is replaced and used.
