The arrangement includes a diaphragm of elastic material having a movable central portion and a connection boss formed at the movable portion. The connection boss has a blind bore in which is fitted an actuator rod for elastic engagement. A retainer is fitted over the outer periphery of the connection boss for restraining deformation of the connection boss.
