As shown in FIG. 6, a steam hole 2 is formed in the outer lid 1 of the rice cooker, and a steam exhaust valve 6 is installed on the back side of the steam hole 2. In addition, a synthetic resin lid ring 3 is fitted on the inner periphery of the back surface of the outer lid 1.
A cylindrical steam hole portion 5 is integrally formed on the inner peripheral edge of the steam hole 5 . This steam hole portion 5 functions to support the steam exhaust valve 6, and a recess 11 formed on the back surface of the outer lid 1 is secured by a locking pawl 10 (see FIG. 7) formed on the outer periphery of the steam hole portion 5. is engaged with. Further, the upper end of the steam hole portion 5 is tightly attached to the lower surface of the outer cover 1 around the steam hole 2 via a packing 12.

屈曲できるようにしている。 The lid ring 3 is fitted onto the inner periphery of the back surface of the outer lid 1, and functions to support the heat sink 13, the heat insulating material 14, and the like. The steam hole portion 5 described above does not necessarily need to be formed integrally with the lid ring 3, but depending on the number of parts,
For reasons such as reducing the number of molds, a connecting portion 4 is provided on the inner peripheral edge of the lid ring 3, thereby integrating the two. Further, a V-shaped notch 15 is formed in the connecting portion 4, so that the steam hole portion 5 can be bent freely.
ところで、連結部４に上記のようなＶ形ノツチ
１５を形成した場合、外蓋１の熱変形や成形寸法
のバラツキに対する追従性に欠けるために、次の
ような問題がある。
By the way, when the above-mentioned V-shaped notch 15 is formed in the connecting portion 4, the following problem arises due to lack of ability to follow thermal deformation of the outer cover 1 and variations in molded dimensions.

り、蒸気漏れの原因となることがある。 That is, when the outer cover 1 is deformed so as to bulge upward, the steam hole portion 5 rotates in the direction shown by arrow a in FIG. A gap δ is created between them, and steam leaks into the interior of the outer lid 1 from this portion. Further, if there is a misalignment between the steam hole 2 and the steam hole portion 5 of the outer lid 1, the close contact between the gasket 12 and the outer lid 1 may become uncertain, which may cause steam leakage.
そこで、この考案は連結部４の構造に改良を加

The rice cooker lids according to the embodiments shown in FIGS. 1 to 4 are basically conventional ones (FIGS. 6 and 7).
(see figure), the same parts are designated by the same reference numerals and their explanations will be omitted.

由な方向に変形しうるように設定される。 The feature of this invention is that the connecting part 4 of the steam hole part 5 provided integrally with the lid ring 3 is provided with an elastically deformable part 8, and as shown in FIG. The connecting portion 4 is formed to have a thin wall over its entire width, and the central portion of the thin wall portion is bent over the entire width of the connecting portion 4 to form a bellows shape. The thickness of this bellows portion is set so that it can be deformed in any direction due to the flexibility of the material itself.

A thin connecting plate is formed integrally between the connecting portion 4a on the side of the lid ring 3 and the connecting portion 4b on the side of the steam hole portion 5 and extending parallel to the tangent line of the lid ring 3. This connecting plate is formed to have a width or thickness that allows it to be deformed in any direction due to the flexibility of the material itself at the connecting portions 4a and 4b at both ends.

As described above, in this invention, the expansion/contraction deformation part 8 is formed in the connection part 4 of the steam hole part 5 by a thin bellows part or a thin connection plate, so that the deformation of the outer cover 1 and Even if there is a horizontal or vertical positional shift between the steam hole 2 and the steam hole portion 5, the steam hole portion 5 can freely follow in any direction by the expansion/contraction deformation portion 8. Therefore, a seal between the steam hole portion 5 and the outer lid 1 is ensured, and there is an effect of preventing steam from leaking into the inside of the outer lid 1.
