弁装置。A conical surface is formed by expanding the diameter of the first cylindrical member attached to the shell outward on the open end side, and a flange is formed on the end side of the conical surface, thereby creating a negative pressure. A second cylindrical member having a joint portion to which piping is connected is integrated with the first cylindrical member by fitting an opening on the opposite side of the joint portion and the flange to each other. A check valve device for a negative pressure booster, wherein a valve member having the conical surface as a valve seat and biased toward the valve seat by a valve spring is disposed in a gap formed between both cylindrical members.
