特徴とする逆止弁。A shock absorber is provided between the inner wall of the valve body and the swing arm to suppress movement of the valve body in the direction of closing the valve seat, and
The shock absorber includes a cylinder that stores fluid in a valve box in a communicating state, a piston inserted into the cylinder, and a viscous resistance force applied to the valve body by moving the fluid in the cylinder by the movement of the piston. A check valve comprising a resistance flow path that provides a resistance flow path.
