PROBLEM TO BE SOLVED: To easily mount a valve to a shaft and thereby reduce the number of assembly processes and improve the quality in a passage opening/closing valve.SOLUTION: In a passage opening/closing valve 10, a protruding part 38 which protrudes from the other end surface of a body part 36 in a valve 14 in an axial direction is provided. When the valve 14 is assembled to a shaft 44, a guide part 40 of the valve 14 is moved along a groove part 48 of the shaft 44. Then, the valve 14 is coupled to the shaft 44 with a fastening bolt 52 in a state where the valve 14 is moved to a point where the protruding part 38 contacts with an outer peripheral surface of the shaft 44 to be easily assembled to the shaft 44.SELECTED DRAWING: Figure 1 【課題】流路開閉弁において、バルブをシャフトに対して容易に組み付け可能とすることで、組付工数の削減を図ると同時に品質の向上を図る。【解決手段】流路開閉弁１０において、バルブ１４における本体部３６の他端面から軸方向に突出した突部３８を設け、前記バルブ１４を前記シャフト４４へと組み付ける際、前記バルブ１４のガイド部４０をシャフト４４の溝部４８に沿って移動させ、前記突部３８を前記シャフト４４の外周面に当接するまで移動させた状態で締結ボルト５２によって連結することで、容易に組み付けることができる。【選択図】図１
