The present invention provides a stabilizer manufacturing apparatus (S) that is adapted to bond a rubber bush (3), which is a bush made of rubber disposed between a stabilizer (1) and a vehicle body, to a rubber bush bonding location (1s) where an adhesive layer of the stabilizer (1) is formed. The stabilizer manufacturing apparatus is provided with: a curing furnace (R) for heating the stabilizer (1), which is conveyed by a manufacturing line conveying unit (4) and has the rubber bush bonding location (1s) with which the rubber bush (3) is press-contacted, and performing the bonding; a heat source device (5) that heats air; a blower device (f1, f2, f3) that sends the air heated by the heat source device (5) as hot air; and a plurality of nozzles (7) that are disposed along the manufacturing line conveying unit (4) in the curing furnace (R) and blow the hot air against, at a near position from, a location (1a1) in the vicinity of the rubber bush bonding location (1s) of the stabilizer (1).
