摘要： A diaphragm valve includes a valve body, a diaphragm, a bonnet, an operation mechanism, and a fixing mechanism. The fixing mechanism includes a clamping member for integrally sandwiching and fixing, from both right and left sides, circumferential edges of both the bonnet and the valve body. A circular pressing member for pressing a circumferential edge of the diaphragm from above is interposed between the diaphragm and the bonnet and has convex portions and concave portions. The convex portions fit into notches provided at the circumferential edge of the diaphragm or the valve body, and the concave portions are fitted by protrusions provided at the circumferential edge of the diaphragm or the valve body.
