ELECTRIC POWER-FEEDING STRUCTURE Abstract An electric power-feeding structure for feeding electric power to a moving body (2) which is driven to be raised or lowered, includes: an arm (12) having a distal end connected to the moving body (2) movably in a horizontal direction and a proximal end rotatably driven to swing, to thereby drive the raising or lowering of the moving body (2). An electrical wire (21) is routed alongside the arm (12), and one end of the electrical wire (21) extending from the distal end is connected to the moving body (2). In a vicinity of a rotating shaft (13) of the arm, the electrical wire (21) is fixed to the arm (2) at a first fixing point (21b) and to a base for supporting the arm at a second fixing point (21a). The first fixing point (21b) is provide on a straight line defined by the rotating shaft (13) and the second fixing point (21a) when the arm (12) is at an intermediate position of its swinging range. )- 0: -f (' |
