は内蓋７に押圧し蓋されている。 According to FIG. 2, reference numeral 10 is a lid knob, and the inside thereof is a cylindrical hollow part with two stages. The lid knob 10 has a first hollow part 10a and a second hollow part 10b, a spring 11 is inscribed in the first hollow part 10a, and a spring seat 10c is provided on the ceiling. Further, a screw 13 is formed on the inner peripheral surface of the second hollow portion 10b, and the lid bolt 5 passes through the through hole 4a of the outer lid 4 and is screwed into the screw 13 of the lid knob 10. The spring 11 has a diameter at the middle part 11c larger than the diameter at both ends 11a and 11b, and the lid knob 10
It slides using the first hollow part 10a as a guide, and the distal end part 11b fits into the convex part 3a of the head of the shaft 3 to prevent it from coming off from the shaft 3. The shaft 3 is inscribed in the through hole 5a of the lid bolt 5, and the head 3
a is a convex portion 3 inscribed in the spring 2 and forming a seat;
a, and is prevented from coming off by a collar 3b having a larger diameter than the through hole 5a of the lid bolt 5. Further, the lower part of the shaft 3 is formed into a hemispherical surface 3c so that it will not be damaged even when the inner lid knob 6 is pressed. The lid bolt 5 integrally constitutes the lid knob 10, the outer lid 4, and the lid bolt 5, and also constitutes a through hole 5a for vertical movement of the shaft 3, which serves as a retainer for the shaft 3 to come off. The inner cover knob 6 secures the inner cover 7 between the inner cover bolts 8 and the inner cover knob 6.
and transmits the pressing force of the shaft 3 to the inner lid 7. Pot 9
is pressed against the inner lid 7 and covered.

以上のように本発明によれば次の効果が得られ
る。 As described above, according to the present invention, the following effects can be obtained.

１シヤフトの径が従来の約1/2になるので熱伝
導が減り内蓋つまみの温度が低くなつた。1. Since the diameter of the shaft is approximately 1/2 that of the conventional one, heat conduction is reduced and the temperature of the inner lid knob is lower.

２スプリングの座が安定し、スプリングの下端
がシヤフトの座から外れる心配がなくなつた。2 The spring seat is stable, and there is no longer any worry that the lower end of the spring will come off the shaft seat.

３スプリングの中央部が蓋つまみの穴に外接し
て摺動時に座くつなく安定した作動が得られ
る。２段中空によりスプリングのかみこみがな
くなる。3. The center part of the spring circumscribes the hole in the lid knob, ensuring stable operation without sitting during sliding. The two-stage hollow structure eliminates the need for spring bite.

４無意識に組立てもシヤフトの凸部にスプリン
グの両先端の片方が嵌合し、組立やすいもので
ある。4. Even if assembled unconsciously, one of the ends of the spring fits into the convex part of the shaft, making it easy to assemble.

Claims

[Claims]

1 The inside of the lid knob of the outer lid is made into a two-stage cylindrical hollow part, a pressurizing spring is inscribed in the first hollow part of this hollow part, and a screw is formed on the inner surface of the second hollow part of the hollow part. Then, screw the lid bolt onto this screw, sandwich the outer lid, and fix it with the lid bolt.The shaft that passes through the center of the lid bolt is arranged so that it can be moved up and down, and the head of the shaft can be removed. The gas rice cooker is provided with a flange that comes into contact with the lid bolt so that the lid bolt does not move, and has a convex part formed on the head part into which one end part of a coiled spring having a diameter larger in the middle part than both ends is fitted.
