Zusammenfassung:To provide a channel switch valve having a structure capable of easily managing an inclination of a case at welding.SOLUTION: In a channel switch valve 1, a valve shaft 40 attached to a ball valve body 20 is disposed so as to saddle a valve body 10 and a gear case 52. A driving portion 60 rotation-driving the ball valve body 20 via the valve shaft 40 has a large-diameter gear 67 attached to a columnar portion 41 of the valve shaft 40. The gear case 52 has a bottom wall portion 53 disposed so as to block an opening of the valve body 10, a bearing portion 56 provided on the bottom wall portion 53 and rotatably supporting the valve shaft 40, and a plane portion 58a provided on an inner surface 53b of the bottom wall portion 53 corresponding to a peripheral wall portion 16 of the valve body 10.SELECTED DRAWING: Figure 7 【課題】溶着時のケースの傾きを容易に管理できる構造を有する流路切換弁を提供する。【解決手段】流路切換弁1は、ボール弁体20に取り付けられる弁軸40が、弁本体10とギヤケース52とにまたがって配置されている。弁軸40を介してボール弁体20を回転駆動する駆動部60が、弁軸40の円柱部41に取り付けられる大径ギヤ67を有している。そして、ギヤケース52は、弁本体10の開口を塞ぐように配置される底壁部53と、底壁部53に設けられ、弁軸40を回転可能に支持する軸受部56と、弁本体10の周壁部16に対応して底壁部53の内面53bに設けられた平面部58aと、を有している。【選択図】図7
