動機構。[Claims for Utility Model Registration] A valve opening/closing drive mechanism for opening and closing a valve by moving a valve element relative to a valve seat using a pressure cylinder as a driving source, comprising: , a piston that applies driving force through various power transmission parts, and a large-area end face of one end face of this piston, configured so that fluid pressure acts on it, and allows fluid pressure to be introduced and extracted. A constant fluid pressure is always applied to the first cylinder chamber configured in the first cylinder chamber, and the small area side end face formed on the other end face of the piston and having an area smaller than the area of the large area side end face. A valve opening/closing drive mechanism using a pressure cylinder, characterized in that it has a second cylinder chamber configured as follows.
