    • A power transmission device for transmitting a driving force from a vehicle-mounted driving source to a vehicle-mounted rotary device includes a driving rotor mechanically coupled to the vehicle-mounted driving source via a belt, and a driven rotor disposed coaxially with the driving rotor and mechanically coupled to a drive shaft of the vehicle-mounted rotary device. Furthermore, the power transmission device is provided with a magnetic join portion disposed in at least one of the driving rotor and the driven rotor, and the magnetic join portion is adapted to transmit a rotary driving force from the driving rotor to the driven rotor by a magnetic force, while keeping a predetermined clearance between the driving rotor and the driven rotor. Thus, in the power transmission device, a natural frequency can be made much lower than a frequency of vibration generated from the vehicle-mounted rotary device in idling of a vehicle.
    • 用于将驱动力从车载驱动源传递到车载旋转装置的动力传递装置包括经由皮带机械联接到车载驱动源的驱动转子和与驱动转子同轴设置的从动转子 并且机械地联接到车载旋转装置的驱动轴。 此外,动力传递装置设置有设置在驱动转子和从动转子中的至少一个中的磁连接部,并且磁接合部适于将驱动转子的旋转驱动力传递到从动转子 同时在驱动转子和从动转子之间保持预定的间隙。 因此,在动力传递装置中,固有频率可以比在车辆空转时从车载旋转装置产生的振动频率低得多。
