従来では、蓋体または筐体本体を撓ませてヒンジ部の軸を軸穴に嵌入していたので、軸と軸穴の掛かり量を大きくできないという課題があった。
例えば、図１（ａ）、図１（ｂ）に示すように、蓋体１００を筐体１０１に組み付ける場合に、従来は、蓋体１００を撓ませて軸１０２を軸穴１０３に嵌入させていた。
この構成では、図１（ｂ）、図１（ｃ）に示すように、軸１０２と軸穴１０３の掛かり量ｂよりも蓋体１００の撓み量ａを大きくしないと、蓋体１００を筐体１０１に組み付けられない。このため、蓋体または筐体本体が大きく撓まない部材で形成されている場合には、不可避的に掛かり量を小さくしなければならず、蓋体が脱落しやすくなる。Conventionally, since the lid or the housing body is bent and the shaft of the hinge portion is fitted into the shaft hole, there is a problem that the amount of engagement between the shaft and the shaft hole cannot be increased.
For example, as shown in FIGS. 1A and 1B, when the lid 100 is assembled to the housing 101, conventionally, the lid 100 is bent and the shaft 102 is fitted into the shaft hole 103. It was.
In this configuration, as shown in FIG. 1B and FIG. 1C, the lid 100 is mounted on the housing unless the bending amount a of the lid 100 is larger than the amount b of engagement between the shaft 102 and the shaft hole 103. 101 can not be assembled. For this reason, when the lid body or the housing body is formed of a member that does not bend greatly, the amount of hooking must be inevitably reduced, and the lid body easily falls off.

この発明は、上記のような課題を解決するためになされたもので、蓋体のヒンジ部における軸と軸穴との掛かり量を大きくすることができる電子機器を得ることを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an electronic device capable of increasing the amount of engagement between the shaft and the shaft hole in the hinge portion of the lid.

And a bearing portion having an axial hole along the hinge axis, and a shaft portion provided on the other side of the lid or the housing body and having an axis along the hinge axis, and slid along the hinge axis. a shaft is brought into contact with the bearing portion or the shaft portion of the lid in a state of fitted into the shaft hole Te, e Bei a rotating support the shaft regulates the sliding in a direction out of the shaft hole, the rotation supporting section, hemisphere The protrusion part protruded in the shape is provided, and it contacts the bearing part or axial part of a cover body through a protrusion part, It is characterized by the above-mentioned.

この発明によれば、蓋体のヒンジ部における軸と軸穴との掛かり量を大きくすることができるという効果がある。   According to this invention, there is an effect that the amount of engagement between the shaft and the shaft hole in the hinge portion of the lid can be increased.
