両者を離反する方向に付勢したバネである。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 4, a lever 1o has an arcuate portion 10a projecting in the suppression direction in a part thereof, and the arcuate portion 10a is fitted into the lid 11 so that its outer surface is in contact with the lever 1o. A recessed portion 11a is formed. The inner surface of the recessed portion 11a has an arcuate shape concentric with the arc of the arcuate portion 10a. Reference numeral 12 denotes a shaft that is inserted into the inner surface of the arcuate portion IQa, clamps the arcuate portion 10a with the recess 11a, and is rotatably supported. 13 is arranged between the lever 10 and the lid body 11,
This is a spring that biases the two in the direction of separating them.
１４はレバー１０に設けたレバー押しボタンで、蓋体１
１の外面より露出している。14 is a lever push button provided on the lever 10;
It is exposed from the outer surface of 1.
第５図は上記した蓋体１１の凹部１１ａ近傍部分を示し

けてあり、この穴１１ｂに軸１２の両端を挿入すること
により、軸１２の固定を行う０１１ｃはバネ１３を所定
位置に位置付ける突起で蓋体１１に一体に形成しである
。FIG. 5 shows a portion near the recess 11a of the lid 11 described above. At both ends of the recess 11a, opposite holes 11b are provided. By inserting both ends of the shaft 12 into the holes 11b, , 011c for fixing the shaft 12 is a projection that positions the spring 13 at a predetermined position and is integrally formed with the lid body 11.
上記した軸１２は、第６図に示すように略り字状をなし
、その一端側が上記相対向した穴１１ｂに貫通してあり
、他端側は、蓋体１１に一体に設けた突起１１ｄに当接
し、軸１２が穴１１ｂから抜けたシ、ずれたりするのを
防止している。The shaft 12 described above has an abbreviated shape as shown in FIG. This prevents the shaft 12 from coming out of the hole 11b or being displaced.

タン１４を押し下げると、軸１２を中心として、レバー
１ｏが回転して、本体との嵌合が解除されて、蓋体１２
が開くこととなる。To explain the operation in the above configuration, since the lever 1o is subjected to a rotational force about the shaft 12 by the spring 13, the end of the lever 10 opposite to the end where the lever pushbutton 14 is provided is connected to the main body. When fitted, the main body and the lid 11 are combined, and the lid 11 is in a closed state. When the main body is lifted up with the lid 11 in this state, the force applied to the lever 10 is a downward main body load, and the concave portion 11a of the lid 11 receives this force. Further, when the lever push button 14 is pressed down, the lever 1o rotates around the shaft 12, and the fitting with the main body is released, and the lid body 12 is released.
will open.
上記構成においては、蓋体１１の上にバネ１３を置き、
レバー１０の弧状部１０ａを蓋体１１の凹部−１１ａ上
に置き、穴１１ｂに軸１２を通すだけで、簡単に組み立
てられるという効果がある。In the above configuration, the spring 13 is placed on the lid 11,
The lever 10 has the advantage of being easily assembled by simply placing the arcuate portion 10a on the recess 11a of the lid 11 and passing the shaft 12 through the hole 11b.
又、レバー１０を蓋体１１にねじやリベット等の部品を
使わずに固定しているため、荷重ががかったり、熱サイ
クルがかかった時の信頼性の面で特に効果がある。Furthermore, since the lever 10 is fixed to the lid body 11 without using parts such as screws or rivets, it is particularly effective in terms of reliability when a load is applied or a thermal cycle is applied.
又、同時に、従来のように、軸受板やねじを使用しない
ので、合理化がはかれる。At the same time, since no bearing plates or screws are used as in the conventional case, rationalization can be achieved.
