ABSTRACT:
A valve includes a drive part provided with a piston for driving a valve element in an axial direction, a valve body formed at one end in the axial direction with a valve chamber for accommodating the valve element, and a base seat. The drive part includes leg parts suspended down from one end in the axial direction. The leg parts form a receiving part for accommodating the valve body inside the leg parts. The valve body is inserted into the receiving part so that the valve element of the drive part is accommodated in the valve chamber of the valve body. Then, the base seat is fixed to the leg parts in the state with the seat made to abut against the other end of the valve body in the axial direction so that the valve body is held between the base seat and the drive part.
