And a shaft portion 65 that is rotatably held by the bearing portion 50. The operation part 63 is provided with a cylindrical outer peripheral part on the outer peripheral part of a disk protruding upward. The operation portion 63 is provided with a locking groove 66 for inserting and locking the first urging portion 69 of the kick spring 67 at the lower edge on the opposite side of the lock portion 64. The lock portion 64 has a claw that is detachably locked to the lock claw portion 17 in conjunction with the operation of the operation portion 63. The shaft portion 65 is a relatively short rod-like member provided so as to protrude from the boundary portion between the operation portion 63 and the lock portion 64 to both sides. Here, with respect to the operation member 62, the bearing portion 50 of the second lid member 39 is positioned so as to hold the base portion of the shaft portion 65.

前記キックバネ６７は、コイル状のバネ本体６８と、該バネ本体６８の一端より突出する第１付勢部６９と、前記バネ本体６８の他端より突出する第２付勢部７０とを有するものである。前記バネ本体６８は、前記操作部材６２の軸部６５を除く位置である第２蓋部材３９の凹部５３に収容配置されている。前記第１付勢部６９は、第２蓋部材３９の各挿通溝３７，５５を通って操作部６３の係止溝６６に下側から挿入係止され、該操作部６３を下側より外向きに付勢するものである。前記第２付勢部７０は、第２蓋部材３９の凹部５３の支持壁部５４に沿って上向きに延びるように配置され、該支持壁部５４を操作部６３の操作方向に対して略直交する方向である略水平方向に付勢するものである。また、この第２付勢部７０は、第２蓋部材３９に対して第１蓋部材２５を組み付けることにより、前記凹部５３の壁面（支持壁部５４）と第１蓋部材２５のリブ３８との間に挟み込まれて位置決め保持される。   The kick spring 67 has a coiled spring main body 68, a first urging portion 69 protruding from one end of the spring main body 68, and a second urging portion 70 protruding from the other end of the spring main body 68. It is. The spring main body 68 is accommodated and disposed in the concave portion 53 of the second lid member 39 which is a position excluding the shaft portion 65 of the operation member 62. The first urging portion 69 is inserted and locked from below on the locking groove 66 of the operation portion 63 through the insertion grooves 37 and 55 of the second lid member 39, and the operation portion 63 is removed from the lower side. It is biased in the direction. The second urging portion 70 is disposed so as to extend upward along the support wall portion 54 of the concave portion 53 of the second lid member 39, and the support wall portion 54 is substantially orthogonal to the operation direction of the operation portion 63. It is energized in a substantially horizontal direction, which is a direction to perform. In addition, the second urging portion 70 assembles the first lid member 25 to the second lid member 39, so that the wall surface (support wall portion 54) of the recess 53 and the rib 38 of the first lid member 25 It is sandwiched between and positioned and held.

前記構成の蓋体２４を組み立てる際には、まず、第１蓋部材２５に対して装飾カバー５６を配置し、第１蓋部材２５に対して装飾カバー５６を押圧する。これにより、第１蓋部材２５の弾性係止片３２が装飾カバー５６のフランジ部６１の内端縁に当接し、弾性係止片３２が弾性的に内側に撓み、該弾性係止片３２の先端がフランジ部６１の内端縁を越えると、弾性係止片３２がフランジ部６１の上面に係止する。なお、この第１蓋部材２５と装飾カバー５６の組立時には、前方の係止片３３が殆ど撓まないため、該係止片３３をフランジ部６１の上面に係止させた後、背面側を押圧するようにして係止することが好ましい。その後、係合爪６０を折り曲げて装飾カバー５６と第１蓋部材２５とを離脱不可能に固着する。   When assembling the lid 24 having the above-described configuration, first, the decorative cover 56 is disposed on the first lid member 25, and the decorative cover 56 is pressed against the first lid member 25. As a result, the elastic locking piece 32 of the first lid member 25 abuts on the inner end edge of the flange portion 61 of the decorative cover 56, and the elastic locking piece 32 is elastically bent inward, so that the elastic locking piece 32 When the tip exceeds the inner edge of the flange portion 61, the elastic locking piece 32 is locked to the upper surface of the flange portion 61. When the first lid member 25 and the decorative cover 56 are assembled, the front locking piece 33 hardly bends. Therefore, after the locking piece 33 is locked to the upper surface of the flange portion 61, the rear side is It is preferable to lock by pressing. Thereafter, the engagement claw 60 is bent to fix the decorative cover 56 and the first lid member 25 so that they cannot be detached.

また、第２蓋部材３９の凹部５３にキックバネ６７のバネ本体６８を配置し、第２付勢部７０を支持壁部５４に沿わせて上向きに配置するとともに、第１付勢部６９を挿通溝５５を通して正面側に向けて延びるように位置させる。その後、第２蓋部材３９に対して操作部材６２のロック部６４を貫通させた後、軸部６５を軸受部５０に嵌め込んで回転可能に軸着する。この際、操作部材６２の操作部６３の下縁にキックバネ６７の第１付勢部６９を位置させ、係止溝６６に第１付勢部６９を係止させる。これにより、操作部材６２およびキックバネ６７は、軸受部５０から軸部６５が離脱するような強い外力が加えられない限り、離脱することなく、組付状態が確実に維持される。   Further, the spring body 68 of the kick spring 67 is disposed in the recess 53 of the second lid member 39, the second urging portion 70 is disposed upward along the support wall portion 54, and the first urging portion 69 is inserted. It is positioned so as to extend toward the front side through the groove 55. Thereafter, after the lock portion 64 of the operation member 62 is passed through the second lid member 39, the shaft portion 65 is fitted into the bearing portion 50 and is rotatably attached to the shaft. At this time, the first biasing portion 69 of the kick spring 67 is positioned on the lower edge of the operation portion 63 of the operation member 62, and the first biasing portion 69 is locked in the locking groove 66. As a result, the operation member 62 and the kick spring 67 are reliably maintained in the assembled state without being detached unless a strong external force is applied so that the shaft part 65 is detached from the bearing part 50.

ついで、操作部材６２の操作部６３が露出部３５および露出孔５８を貫通して装飾カバー５６から露出するように、かつ、第１蓋部材２５のリブ３８が第２蓋部材３９の凹部５３内に進入するように、第１蓋部材２５と第２蓋部材３９とを位置調整して配置し、第２蓋部材３９のネジ挿通孔４４を貫通させて第１蓋部材２５のネジ止め部３４にネジを締め付けて固定する。   Next, the operation portion 63 of the operation member 62 passes through the exposed portion 35 and the exposure hole 58 and is exposed from the decorative cover 56, and the rib 38 of the first lid member 25 is in the recess 53 of the second lid member 39. The first lid member 25 and the second lid member 39 are arranged so as to enter the position, and the screw insertion hole 44 of the second lid member 39 is passed through the screw fastening portion 34 of the first lid member 25. Tighten the screws to secure them.

このように、本発明の炊飯器１０では、キックバネ６７のバネ本体６８を操作部材６２の軸部６５を除く位置に配設しているため、軸部６５の突出代を低減できる。その結果、蓋体２４全体の小型化を図ることができる。また、支持壁部５４は、第２付勢部７０による付勢力を蓋体２４の開放方向に対して略直交方向に作用させるように、操作部材６２の操作方向に沿って延びるように設け、操作部材６２の操作方向に対して略直交する方向に作用する構成としている。そのため、操作部材６２を開放操作した際に、蓋体２４の開放方向に対して逆方向に作用する反力（付勢力）を低減できる。その結果、操作部材６２を開放操作したにも拘わらず、ロック部６４が再ロックして蓋体２４を開放できないという不都合を防止できる。   Thus, in the rice cooker 10 of this invention, since the spring main body 68 of the kick spring 67 is arrange | positioned in the position except the axial part 65 of the operation member 62, the protrusion margin of the axial part 65 can be reduced. As a result, the entire lid 24 can be reduced in size. Further, the support wall portion 54 is provided so as to extend along the operation direction of the operation member 62 so that the urging force by the second urging portion 70 acts in a direction substantially orthogonal to the opening direction of the lid 24. The operation member 62 is configured to act in a direction substantially orthogonal to the operation direction of the operation member 62. Therefore, when the operation member 62 is opened, the reaction force (biasing force) acting in the opposite direction to the opening direction of the lid 24 can be reduced. As a result, it is possible to prevent the inconvenience that the lock portion 64 cannot be re-locked and the lid 24 cannot be opened despite the operation member 62 being opened.

さらに、前記第２蓋部材３９に、前記キックバネ６７のバネ本体６８を収容する凹部５３を設けている。しかも、前記第１蓋部材２５には、前記凹部５３内に進入してバネ本体６８を凹部５３との間に挟み込んで位置決めするリブ３８を設けている。そのうえ、操作部材６２の軸部６５を受ける軸受部５０を、第２蓋部材３９に設けている。そのため、操作部材６２およびキックバネ６７を含む蓋体２４の組立作業性を向上できるとともに、組立状態を安定させることができる。   Further, the second lid member 39 is provided with a recess 53 for accommodating the spring main body 68 of the kick spring 67. Moreover, the first lid member 25 is provided with a rib 38 that enters the recess 53 and positions the spring main body 68 between the rib 53 and the first lid member 25. In addition, a bearing portion 50 that receives the shaft portion 65 of the operation member 62 is provided in the second lid member 39. Therefore, the assembly workability of the lid 24 including the operation member 62 and the kick spring 67 can be improved, and the assembled state can be stabilized.
