In a manufacturing device (80) for a flow volume control device (10), a cylinder rod (86) of a cylinder (88) is used to press together a first casing (24) and a second casing (28), and a wire rod (54) is made to generate heat, thereby welding together the inner wall of an engaging groove (52) and an engaging protrusion (40). A load cell (100) detects a load applied to the first casing (24) and the second casing (28), and a load current detection sensor (119a) detects the value of a load current flowing in a cylinder motor (85). On the basis of the load or the load current value, a controller (118) controls the pressing operation of the cylinder (88) with respect to the first casing (24) and second casing (28) when the inner wall of the engaging groove (52) and the engaging protrusion (40) are welded together. |
