Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the fusion bonding of fragments of a synthetic resin laminate by effectively preventing an excessive increase in temperature inside a drum of a separating device for a synthetic resin laminate for use in separating a synthetic resin laminate into a skin material and a cusion material in recycling waste materials from the synthetic resin laminate and improve the durability of the device. SOLUTION: A separating device comprises a drum 3 into which a group of fragments of a synthetic resin laminate is introduced, a screen member 9 and a rubbing member 21 which are adapted to relatively rotate inside the drum 3 so as to impart this group of fragments impact and friction to thereby grind a cusion material of each fragment so as to be separated therefrom, wherein a water discharge means W is provided in the drum 3 which is adapted to discharge water into the drum 3 when the temperature thereinside exceeds a predetermined value and an evacuation means E is connected to the drum 3 which is adapted to evacuate steam produced in conjunction with the discharge of water to the outside of the drum, whereby an excessive increase in temperature inside the drum 3 is prevented by virtue of evaporation of water and evacuation of steam so produced.
