<p>PROBLEM TO BE SOLVED: To provide a lighting device in an extendable pole device for an automobile having a ground connecting structure for connecting the pole with the ground, which is simple and sure. SOLUTION: A drive cord 2 laid in an extendable metal pole 1 is arranged so that the extendable metal pole 1 can be extended and retracted through the operation of a pay-out drive device 3, having a power supply means for a light emitting part 4 provided in the distal end part of the extendable pole 1, which is composed of a core wire 5 laid in the drive cord 2, and the extendable pole 1 itself. In this arrangement, an attaching hole part 8 is inserted for connection on a cylindrical fitting connection part 6 and is communicated with the inner part of the inner peripheral part of an insertion part of an accommodation pipe member 7. Further, a contact plate member 9 having a dog leg-like part 9B fitted in the attaching hole part 8 so that the dog leg-like part 9B is extended inward, is laid between the peripheral surface of the insertion part of the accommodation pipe member 7 and the fitting attaching member 6, and an end part 9A of the metal contact plate member 9 serves as an outer extending end 9A which is exposed tot the outside of the fitting part, and which is used as a connection end.</p> |
