The collector (100) has a resurfaced adhesive layer (3) coated on inner surfaces and outer surface of dust collecting pipes (2a-2f). An inlet port (24a) is formed in an end of the dust collecting pipes in a position close to air-conditioning device (5). An air outlet opening (25a) is formed in another end of the dust collecting pipes in a position close to an air duct (51) for air-conditioning, while pull cords (4a-4f) is arranged along the dust collecting pipes. The pull cord is securely attached to two outer ends and the dust collecting pipes are pulled with the pull cord.
