ール１５として直径ｌＱｍｍのステンレス鋼球を用いた
場合には、蒸気圧が水柱２００ ｍｍとなったときにボ
ール１５が動作する。The above steam pressure can be adjusted by the weight of the ball 15. For example, if the diameter of the exhaust hole 10 is 6 mm and the ball 15 is a stainless steel ball with a diameter of 1Q mm, the steam pressure will be 200 mm of water column. When the ball 15 moves, the ball 15 moves.

て容易に開くことができなくなる。Additionally, if the cooked rice is left for a long time, the inside of the inner pot 27 will naturally cool down, and as the temperature drops, the inner pot 27 will cool down naturally.
The pressure inside becomes negative, and the outer lid 28 cannot be easily opened relative to the rice cooker main body 21.

ところが、この負圧が所定圧（例えば水柱２０ｍｍ）以
上になったとき、ブツシュ９の弁体１２が下方に撓んで
吸気孔５を開き、外気を内なべ２７内に取り入れるため
、内なべ２７内の負圧は解消され、外蓋２８を容易に開
くことができる。However, when this negative pressure exceeds a predetermined pressure (for example, 20 mm of water column), the valve body 12 of the bushing 9 bends downward to open the intake hole 5 and take outside air into the inner pot 27. The negative pressure is eliminated, and the outer cover 28 can be opened easily.

However, the present invention is not limited to this, and as shown in FIG. By providing the protrusion 43 and forcing the fitting 2 into the steam pipe 37 from below, the small sea member 42 rides over the protrusion 43 with its own elasticity and comes into pressure contact with the inner surface of the steam pipe 37.

これによって、調圧装置１は空気漏れなく取付けられる
。Thereby, the pressure regulator 1 can be installed without air leakage.

なお、第５図中、第４図と同一部品には同一番号を付し
て説明を省略する。In FIG. 5, parts that are the same as those in FIG. 4 are given the same numbers and their explanations will be omitted.

また、調圧装置１は外蓋２８ばかりでなく、調理器本体
