  "textContent": "A power transmission device 100 includes an annular transmission unit 10 having an annular first magnetic core 31 and a transmission coil 61 and an annular reception unit 20 having an annular second magnetic core 33 and a reception coil 62. The transmission unit 10 and the reception unit 20 are arranged to face each other. The power transmission device 100 transmits power from the transmission unit 10 to the reception unit 20.The transmission unit 10 and the reception unit 20 are relatively rotatable about a rotation axis 95 passing through a cavity inside the transmission unit 10 and a cavity inside the reception unit 20, the first magnetic core 31 has a structure divided into a plurality of first split cores 32 in a circumferential direction, and the second magnetic core 33 has a structure divided into a plurality of second split cores 34 in the circumferential direction.",
