POWER WIRE RETRACTION DEVICE AND CONTACTLESS INSULATED TORLLEY USING THE SAME

An object of the present invention is to provide a power line introduction device (10) capable of supplying more stable electric power and a non-contact insulation current collector (50) provided with a power line. The power line introduction device (10) of the present invention has a first connection terminal (1a) connected to a power supply line (20) for supplying electric power to the power receiving coil (31b) in a non-contact manner by electromagnetic induction and a second connection terminal (1b). The first connection terminal (1a) has a first lead-out portion (1ab) derived from the first power supply line (20a) to the second power supply line (20b), and a first extension (1ab) intersecting the first lead- 1ac). The second connecting terminal (1b) has a second lead-out portion (1bb) derived from the second power supply line (20b) to the first power supply line (20a), and a second extension (1bb) that intersects the second lead- 1bc). (1ac) and the second extension (1bc) are overlapped with each other,
