INDUCTION RING TYPE POWER TRANSMITTER AND LOCKING DEVICE FOR TUB LID USING IT

摘要

PROBLEM TO BE SOLVED: To provide an induction ring type power transmitter of a new structure capable of achieving the efficiency improvement of driving force and the reduction of a manufacture cost at a high level compatibly by easily adjusting the generation force of an induction ring accompanying magnetic induction between a permanent magnet for induction and an induction ring by a simple structure. SOLUTION: In the induction ring type power transmitter 10, on a transmission route 64 for transmitting the rotary driving force of an electric motor 14 to a member 26 to be driven, the permanent magnet 16 for the induction and the induction ring 18 are arranged respectively rotatably on the same rotation center axis so as to face each other separately and the rotary driving force of the electric motor 14 is transmitted to the member 26 to be driven by the magnetic induction between the permanent magnet 16 for the induction and the induction ring 18. A reinforcing member 118 composed of a ferromagnetic member is fixed to a surface on the opposite side of the surface facing the permanent magnet 16 for the induction in the induction ring 18.
