Abstract
To provide a power transmission structure for a road and a pavement block that eliminate the need for wiring work between the pavement blocks even when power is transmitted from a power source to a load via the pavement block forming the road.SOLUTION: When power is transmitted from a power source to a load via a road formed by laying pavement blocks 8, wireless power supply is used for power transmission between the pavement blocks 8. When an electromagnetic inductive method is used as the wireless power supply, a power supply connection block 20 that receives an alternating current from an AC power supply 6 generates an electro-motive force in a path forming member 53e and transmits power. A plurality of load blocks 30f, 30g and a plurality of load blocks 30h, 30i are respectively disposed on side surfaces of a relay block 80. The path forming members 53f to 53i are connected in parallel to a path forming member 53e, generate electromotive forces in the path forming members of the load blocks 30 disposed at opposite positions, and transmit electric power sent from the path forming member 53e.SELECTED DRAWING: Figure 10
