Abstract
In a fluid control device, a valve body is prevented from being pressed forcefully against a valve seat or the like, and an excessive load is prevented from acting on a motor. A flow rate adjustment device includes a first engagement portion, and a second engagement portion that is capable of moving relative to the first engagement portion and transmitting and receiving rotary force. The flow rate adjustment device includes a valve body that adjusts an opening of a flow passage, and a rod that is coupled to the valve body. The flow rate adjustment device further includes a male screw portion and a female screw portion that are intermeshed so as to be fed relative to each other in the axial direction, a projecting portion that restricts movement of the second engagement portion, and a first cylinder that restricts movement of the rod.
