PROBLEM TO BE SOLVED: To improve the efficiency of a mutual inductive action in a power supplying mechanism which supplies power from a toilet seat supporting body of a heated toilet seat device to a heater in the toilet seat not by using an electric wiring but by using a mutual inductive action. SOLUTION: A primary side core K1 on which the primary coil L1 is wound is arranged at a toilet seat supporting body 10, while the secondary side core K2 on which the secondary coil L2 is wound is arranged at the rear end part of a toilet seat 1, and an inductive auxiliary body Y consists of a ferromagnetic body is arranged so that it is close to both side surfaces of the cores K1 and K2. End surfaces t1 and t2 of the cores K1 and K2 are set in such a manner that they face each other when the toilet seat 1 is in a folded position. The end faces t1 and t2 are rectangular, and their long edges are parallel to or forming right angles to the axis line of a supporting axis 20. When AC power is given to the primary coil L1, an electromotive force generates in the secondary coil L2 by a mutual inductive action. The inductive auxiliary body Y arranged at the sides of the primary side core K1 and the secondary side core K2 are comprised of a ferromagnetic body with a high permeability, so that the magnetic flux density of the sides of the cores K1 and K2 is heightened to improve the electric transmittance efficiency.
