To provide a fluid control valve for, when fastening a resin case directly to a body, enabling the smooth fastening with required fastening force.SOLUTION: A fluid control valve 1 includes a metal body 3 having a main flow path 2, a valve element 4 for adjusting the amount of fluid flowing in the main flow path 2, and a resin case 6 mounted on the body 3 and storing an electric motor 8 for driving the valve element 4. The electric motor 8 includes a motor flange 11 overhanging in the direction perpendicular to a rotary shaft. The body 3 and the case 6 are joined by a plurality of fastening parts 12. Two of the fastening parts 12 are motor side fastening parts 12a for fastening corresponding portions of the body 3 and the motor flange 11 with a corresponding portion of the case 6 held therebetween.SELECTED DRAWING: Figure 2 【課題】樹脂製のケースをボディに直接的に締結する場合に、支障なく必要な締結力で締結できる流体制御弁を提供する。【解決手段】流体制御弁１は、主流路２を有する金属製のボディ３と、主流路２に流れる流体の量を調整する弁体４と、ボディ３に取り付けられ、弁体４を駆動する電動モータ８などを収容する樹脂製のケース６とを備える。電動モータ８は、回転軸に垂直な方向に張り出すモータフランジ１１を備える。ボディ３とケース６とは、複数の締結部１２によって結合される。締結部１２のうちの２つは、ボディ３及びモータフランジ１１の対応部分を、これらの間にケース６の対応部分を挟んで締結するモータ側締結部１２ａである。【選択図】図２
