To provide a solid finishing device for jackets in which the installing location for the steam separator is rechecked, a small-sized formation and space-saving of the device can be carried out, heat outputted from the steam separator is utilized for drying processing for the jacket and it can be utilized sufficiently without applying uselessly the heat energy of the steam.

This invention includes a torso 2 on which a jacket 1 is put, a nozzle 3 for blowing steam inside the jacket 1 put on the torso 2, a heat exchanger 4 provided below the torso 2 for discharging heat of the steam inside the jacket 1 put on the torso 2, and a steam separator 6 for removing water droplets from the steam heat exchanged with this heat exchanger 4 and having its temperature decreased. The steam having water droplets removed with the steam separator 6 is supplied to the nozzle 3. A cylindrical base frame 10 is arranged in its raised state below the torso 2, and the steam separator 6 is arranged within the base frame 10 together with the heat exchanger 4.
