PROBLEM TO BE SOLVED: To provide a flapper valve which can be locked so as not to loosen a cover body to a valve body, and an oil supply port closing device using the flapper valve, in an oil supply port closing device making a pressure regulating valve built in the flapper valve assembled with the cover body and the valve body.SOLUTION: A flapper valve is supported so as to rotate with respect to a device body of an oil supply closing device which is fixed in the inside of an oil supply pipe and is equipped with an oil supply port. The flapper valve has a cover body, a valve body, a pressure regulating valve, a lock body, and a pressure regulating valve spring which energizes the pressure regulating valve. The pressure regulating valve, the lock body, and the pressure regulating valve spring are built between the cover and the valve body while the cover body and the valve body are assembled. The lock body is hooked to the cover body while being energized to the cover body by the pressure regulating valve spring, and is hooked to the valve body so as to prevent the rotating of the lock body to the valve body. The cover body is locked to the valve body so as not to rotate.SELECTED DRAWING: Figure 3

    【課題】蓋体及び弁体を組み付けたフラッパ弁に調圧弁を内蔵する給油口閉鎖装置において、弁体に対して蓋体が意図せずに緩まないようにロックすることができるフラッパ弁及びそれを使用した給油口閉鎖装置を提供する。【解決手段】給油管の内側に固定され給油口を備える給油口閉鎖装置の装置本体に対して回転可能に支持されるフラッパ弁であって、フラッパ弁は、蓋体と、弁体と、調圧弁と、ロック体と、調圧弁を付勢する調圧弁用バネとを有しており、調圧弁とロック体と調圧弁用バネとは、蓋体と弁体とを組み付けた状態で、蓋体と弁体との間に内蔵されており、ロック体は、調圧弁用バネによって蓋体に対して付勢された状態で蓋体に掛合すると共に、弁体に対してもロック体が自転不能となるように弁体に掛合し、ロック体を介して蓋体が弁体に対して自転不能な状態にロックされる給油口閉鎖装置用のフラッパ弁である。【選択図】図3
