体３が不用意に開くのを防止している。[Embodiment] FIGS. 1 to 4 show an embodiment of the present invention, in which an opening 2 is formed in a side surface of a case body 1, and a flat lid 3 is detachably attached to the opening 2. Then, a rotary shaft 4 having an elliptical cross section whose major axis direction is orthogonal to the surface of the lid 3 is provided at both ends of the lower portion of the lid 3, and an L-shaped projecting piece is laterally provided at both ends of the lower portion of the opening 2. Forming a receiving portion 5 into which the rotating shaft 4 is fitted,
Approximately 180 from the position where the opening 2 is closed with the rotating shaft 4 as a fulcrum to the position where it abuts on the lower side surface of the opening 2 of the case body.
The lid body 3 is rotatable, and a retaining boss 6 is provided in a protruding manner on the outer surface of the case body 1 facing the tip of the vertical piece of the receiving portion 5.
The distance between the inner surface of the vertical piece of the receiving portion 5 and the outer surface of the case body 1 is made substantially equal to the major axis of the rotating shaft 4, and the retaining boss 6 is provided.
The distance between the tip of the rotating shaft 4 and the inner surface of the vertical piece of the receiving portion 5 is slightly shorter than the minor axis of the rotating shaft 4. In the example,
The case body 1 is composed of a body 1a made of synthetic resin and a cover 1b, and an opening 2 is formed on a side surface of the cover 1b. Engaging claws 7 that engage with both side edges of the opening 2 are provided on both side edges of the lid body 3, and the engaging claws 7 are located on the opening 2 side when the lid body 3 is closed. The lid 3 is prevented from being inadvertently opened by engaging with the edge.
以下、実施例の動作について説明する。いま、蓋体３に
突設されている回動軸４は断面が楕円形となっており、
この回動軸４が嵌合されるＬ字型の突片よりなる受け部
５の垂直片内面とケース本体１外面との間隔を回動軸４
の長径と略等しくしているので、回動軸４を中心として
蓋体３を回動して容易に且つスムーズに開閉することが
できるようになっている。The operation of the embodiment will be described below. Now, the rotary shaft 4 protruding from the lid 3 has an elliptical cross section,
The distance between the inner surface of the vertical piece of the receiving portion 5 formed of an L-shaped projection to which the rotating shaft 4 is fitted and the outer surface of the case body 1 is set to the rotating shaft 4.
Since the length is substantially equal to the major axis of the lid 3, the lid 3 can be pivoted about the pivot shaft 4 to be opened and closed easily and smoothly.
一方、受け部５の垂直片内面とケース本体１外面の間隔

の回動軸４を開口２の受け部５に装着する場合には、第
２図に示すように、回動軸４の短径を受け部５の上方開
口に一致させて押し込めば良く、工具を用いることなく
簡単に装着できることになる。このとき、受け部５の垂
直片は、若干外方に撓むことになる。なお、蓋体３を取
り外す場合には、上記動作の逆手順によって回動軸４を
受け部５から離脱させることにより、工具を用いること
なく容易に取り外すことができる。On the other hand, since the distance between the inner surface of the vertical piece of the receiving portion 5 and the outer surface of the case body 1 is made slightly shorter than the minor diameter of the rotating shaft 4, the lid 3
When the rotating shaft 4 of the rotary shaft 4 is attached to the receiving portion 5 of the opening 2, as shown in FIG. It can be easily installed without using. At this time, the vertical piece of the receiving portion 5 is slightly bent outward. When the lid 3 is removed, the rotary shaft 4 is detached from the receiving portion 5 by the reverse procedure of the above operation, so that the lid 3 can be easily removed without using a tool.
ところで、上述のようにして装着された蓋体３に第３図

４を中心として回動（図中、点線で示す）することによ
って外力を吸収するので、回動軸４が受け部５から離脱
することがなく、蓋体３が不用意に外れないようになっ
ている。また、第４図に示すような外力が加わった場合
にあっても、回動軸４の長径が受け部５の上方開口幅
（回動軸４の短径よりも若干短い）よりもかなり長くな
っているので、回動軸４が受け部５から離脱することが
なく、蓋体３が不用意に外れることがない。すなわち、
実施例にあっては、蓋体３を所定の角度に開いた状態
（水平状態）で回動軸４の短径を受け部５の上方開口に
一致させ、回動軸４に上方向の力を加えた場合にのみ、
回動軸４が離脱できるようになっているので、蓋体３に
外力が加わっても不用意に外れることがない。なお、蓋
体３を閉じた場合において、回動軸４が受け部から抜け
難い状態になっており、外力が加わっても不用意に外れ
ることがないことは言うまでもない。By the way, when an external force as shown in FIG. 3 is applied to the lid body 3 mounted as described above, the lid body 3 rotates about the rotation shaft 4 (indicated by a dotted line in the figure). By doing so, the external force is absorbed, so that the rotary shaft 4 does not separate from the receiving portion 5, and the lid 3 is prevented from being accidentally removed. Even when an external force as shown in FIG. 4 is applied, the major axis of the rotating shaft 4 is considerably longer than the upper opening width of the receiving portion 5 (slightly shorter than the minor axis of the rotating shaft 4). Therefore, the rotating shaft 4 does not come off from the receiving portion 5, and the lid 3 does not come off accidentally. That is,
In the embodiment, in the state where the lid 3 is opened at a predetermined angle (horizontal state), the minor axis of the rotary shaft 4 is made to coincide with the upper opening of the receiving portion 5, and an upward force is applied to the rotary shaft 4. Only if you add
Since the rotating shaft 4 can be detached, it does not accidentally come off even if an external force is applied to the lid 3. It is needless to say that when the lid 3 is closed, the rotation shaft 4 is in a state where it is difficult to come off from the receiving portion and does not come off accidentally even if an external force is applied.

きるという効果がある。[Advantages of the Invention] As described above, the present invention has an opening formed in the side surface of the case body, and a flat plate-like lid is detachably attached to the opening. A rotary shaft having an elliptical cross section that is orthogonal to the rotary shaft is projectingly provided, and a receiving portion formed of an L-shaped projecting piece to which the rotary shaft is fitted is formed laterally at both lower end portions of the opening. Approximately 180 from the position that closes the opening with the fulcrum to the position that contacts the lower side surface of the opening of the case body.
The lid body is rotatable, and a retaining boss is projectingly provided on the outer surface of the case body facing the tip of the vertical piece of the receiving portion, and the gap between the inner surface of the vertical piece of the receiving portion and the outer surface of the case body is rotated. Since the distance between the tip of the retaining boss and the inner surface of the vertical piece of the receiving part is made slightly smaller than the minor axis of the rotating shaft, The lid can be easily attached by fitting the turning shaft into the receiving portion from the minor axis direction in a horizontal state, and even though the lid is easily attached in this way, the lid can be easily attached. In the two stable states in which the opening is closed by the body and the lid is opened to the position where it abuts on the lower side surface of the opening of the case body, the rotation shaft is fitted into the receiving portion at the long diameter portion. The effect is that the lid can be removed with difficulty even if external force is applied. That.
