₁ and 5a ₁ and the upper plate (5b) also has a bifurcated shape.
b ₁ and 5 b ₁ are provided. When doing so, as described in detail in the section of the above-mentioned action, the thermocouple (2) is passed through the through hole (3) of the lower piece (1a) of the U-shaped section of the fixture (1), and the enlarged portion is formed. After contacting the upper piece (1b) of the U-shaped section in (2a), a fixing leaf spring (5) having a U-shaped section is inserted into the space (1c) in the U-shaped section from its side. Notch (6),
When the thermocouple (2) is attached to the (6) so that the thermocouple (2) is located in the enlarged portion (2a), the upper piece (1b) and the upper plate portion (5) of the fixing leaf spring (5) ( 5b) and fixed by holding,
Attached to the fixture (1).

Further, fold the fixing leaf spring (5) by bending the tips of the spring pieces (5a ₁ ) and (5a ₁ ) of the lower plate portion (5a) of the pressure contact portions (5a ₂ ) and (5a ₂ ) downward. The bent portions (5a ₃ ) and (5a ₃ ) are bent, and the ends of the bent portions (5a ₃ ) and (5a ₃ ) are bent in the horizontal direction to form horizontal portions (5a ₄ ) and (5a ₄ ). The length from the curved portion (5a ₃ ) to the closed end edge of the notch (6) provided in the lower plate portion (5a) is defined as the insertion side of the fixing leaf spring (5) into the fixture (1). Is the edge of the fixture (1) on the opposite side,
It was made slightly longer than the length of the through hole (3) of the fitting (1) with the hole side edge on the insertion side. Also, the spring pieces (5b ₁ ) of the upper plate (5b), (5
contact portion of b ₁₎ (5b _2), bent portion by bending the tip above the (5b ₂₎
(5b ₃ ), (5b ₃ ), and the ends of the bent portions (5b ₃ ), (5b ₃ ) were bent horizontally to form horizontal portions (5b ₄ ), (5b ₄ ). Then the bent portion height (5b ₃₎ higher than the height of the enlarged portion of the thermocouple (2) (2a), one of the bent portion of the spring piece (5b ₁₎ (5b ₃₎ and a horizontal portion ( 5b ₄₎ and has the other spring piece (larger than the diameter of the bent portion of 5b ₁₎ (5b ₃₎ and a horizontal portion (5b ₄₎ the distance between the bulging majority (2a).
The distal end side (5b ₅ ) of the pressure contact portion (5b ₂ ) that is bifurcated is narrow in width and relatively flexible.

When installing the fixing leaf spring (5) in the space (1c) inside the U-shaped part of the fixture (1), bend the part (5)
Since the upper end of b ₃ ) contacts the bottom surface of the upper part of the fixture, both pressure contact parts (5b
The tip side of ₂ ) is located below and below the lower surface of the bulge (2a). Also since the bent portions a distance of (5b ₃₎ was larger than the diameter of the bulging majority (2a), the bent portion (5b ₃₎ can pass through the sides of the enlarged portion (2a). Then, when the fixing leaf spring (5) is further inserted, the bent portion (5b ₃ ) passes through both sides of the enlarged portion (2a) and the pressure contact portion.
(5b ₃ ) enters the lower surface of the enlarging part (2a) and bends
Both (5b ₃ ) and the press contact part (5b ₂ ) are not disturbed by the enlarged part (2a).

At this time, due to the deformation of the tip side (5b ₅ ) of the pressure contact portion (5b ₂ ) that is bifurcated and has a narrow width and is easy to bend, the bent portion (5b
Even though the upper end of b ₃ ) is pressed against the lower surface of the upper piece (1b), the pressure contact part (5b ₂ ) has an enlarged part (2b) as shown in FIG.
Press on the bottom surface of a).

The fixing plate spring (5) is caught by the edge of the bent portion of the downward of the lower plate portion thereof (5a) (5b ₃₎ is lower piece of the U-shaped portion (1a), the notch ( 6) With (6), the fixing leaf spring (5) can be prevented from coming off in the horizontal direction.

In the above embodiment, the horizontal portion (5b ₄ ) of the upper plate portion (5b) moves while being in contact with the lower surface of the upper piece (1b) of the U-shaped portion while the fixing leaf spring (5) is being attached. The lower plate (5
Since the horizontal part (5a ₄ ) of (a) also moves while contacting the upper surface of the lower piece (1a) of the U-shaped part, the fixing leaf spring (5) can be mounted more smoothly. Also, after mounting the fixing leaf spring (5), the spring piece (5a ₁ ) of the lower plate (5a) enters without a gap between the vertical piece (1d) of the U-shaped portion and the thermocouple (2). , Even if there is a gap between the through hole (3) of the lower piece (1a) of the U-shaped portion and the thermocouple (2), the thermocouple (2)
Does not rattle horizontally.

In the above embodiment, the lower plate portion (5a) of the fixing leaf spring (5)
The downward horizontal part (5a ₃ ) of the lower part of the lower plate (5a) was prevented from slipping out in the horizontal direction, but the lower plate part (5a) was not provided with a bent part as shown in FIGS. 12 and 13. The length from the bent portion (5b ₃ ) to the closed end edge of the notch (6) provided in the upper plate portion (5b) is
Attachment (1) on the side opposite to the insertion side of the fixing leaf spring (5b)
And the edge of, and slightly longer than the length of the insertion side of the hole edge of the through hole (3) of the mounting device (1), coming off its own horizontal direction by the bent portion (5b ₃₎ I tried to prevent.

Then, as shown in FIG. 12, the bent part (5b ₃ ) is
When it comes off from the bottom surface of b), the pressure contact part (5b ₂ )
Press on the bottom surface of a).

In the above embodiment, the distance between the pressure contact portions of one and the other of the fixing leaf springs (5) is the same in the first half and the second half, but as shown in FIG. 14, the first half is expanded by the thermocouple (2). The diameter may be larger than the diameter of the portion (2a) and the latter half may be smaller, and in this case, the thermocouple (2) can be inserted more easily.

(Effects of the Invention) Thus, according to the inventions of claim 1 and claim 2,
Since the thermocouple was clamped and fixed by mounting the U-shaped fixing leaf spring in the space of the U-shaped section of the fixture, the screw locking means and screwing torque as in the conventional ones for fixing the thermocouple with screws. No need for the restriction measures, the assembly is simplified, and the thermocouple can be removed only by pinching and removing the fixing leaf spring, which has the effect of simplifying maintenance. Further, according to the invention of claim 1, at least one of an upward bending portion provided at the tip of the upper plate portion of the fixing leaf spring or a downward bending portion provided at the tip of the lower plate portion. The length from the bent portion to the closed end edge of the notch is provided so that the end of the attachment on the side opposite to the insertion side of the fixing leaf spring, the insertion side of the through hole, and the hole side edge. Since the length of the fixing leaf spring is slightly longer than the distance between The effect that the fixing leaf spring is prevented from coming off in the horizontal direction.

Further, according to the invention of claim 2, when the fixing leaf spring is mounted on the U-shaped portion of the fixture, the upper end of the bent portion abuts the lower surface of the upper piece of the fixture, so that the tip end side of both press contact portions is the enlarged portion. Located below and below the lower surface of the. Further, since the interval between the bent portions is larger than the diameter of the enlarged portion, the folded portion can pass on both sides of the enlarged portion. When the fixing leaf spring is further inserted, the bent part passes through both sides of the enlarged part and the pressure contact part enters the lower surface of the enlarged part, and the thermocouple can be easily inserted in the notch without being disturbed by the enlarged part. When the bent portion is disengaged from the lower surface of the upper piece, the pressure contact portion presses against the lower surface of the enlarged portion to support the thermocouple. Moreover, the thermocouple is contacted with the closed end edge of the notch, and the bent portion is hooked on the upper end edge of the fixture to prevent the fixing leaf spring from coming off in the horizontal direction.
