壁3口コンセントに、2口＋アース線のコードを挿す用
問題なく使えました。近所の店舗では見つけられず、Amazonでの購入です。 アース線取り付けるところのネジは外れるので、アース線接続部品が丸タイプでも輪を切る必要なく固定する事ができます。 色味は昔っぽいベージュです。もう少し白い方が私は好みです。

    Full content visible, double tap to read brief content.

    デスクトップPCなどを繋ぎたいとき、壁のコンセントが3P（接地極付き）だと、普通の2Pプラグ＋アース線の組み合わせが上手くまとまらず困ることがありますが、そんな時にこのアダプタがとても重宝します。

    サンワサプライ製で安心感がある上に、他社と比べても安いので何度かリピート買いしています。免許はありますが、電気工事でわざわざコンセントごと交換しなくても、これ一つで手軽にアース接続ができるので助かっています。

    ただし、実際に使っていて少し気になったことが2つありました。

    一つは、PCやモニターなどの太くて重いケーブルを繋いだときです。コードの重みに引っ張られて、コンセントに挿した根元の部分が少しガタガタと不安定になりやすい気がします。

    もう一つは、アース線を留めるネジの部分。Y字端子が収まるようにネジの周りが一段凹んだ作りになっているのですが、このスペースが少し狭いです。アース線自体の長さに余裕がない時は、この狭い凹みに端子を合わせるのに少し手間取りました。ここがもう少し広ければさらに使いやすかったなと思います。

    いくつか惜しい部分も書きましたが、機能としては申し分なく、値段以上の価値はある良い商品だと思います。同じようなコンセント環境で悩んでいる方にはおすすめです。
