  • Patent number: 9353803
    Abstract: A power transmitting apparatus comprising a switching device for switching an urging device between an urging force applying position wherein an abutment between the other end of the urging device and the pressure member is kept to apply the urging force of urging device to the pressure member when the intermediate member is moved toward the pressure member, and an urging force cutting-off position wherein the other end of the urging device is separated from the pressure member to cut-off the urging force of urging device to the pressure member when the intermediate member is moved toward the pressure member. In some embodiments, the urging device is set at the urging force applying position while the intermediate member is stopped when the vehicle is stopped and the urging device is set at the urging force cutting-off position while the intermediate member is rotated when the vehicle is running.

  • Patent number: 8379334
    Abstract: A biasing spring is interposed between a coupling plate and a covering section while being compressed from its natural length. The biasing spring biases, by its resilient force, a lens unit toward a ?Z side to bring a surface of the lens unit at the ?Z side into contact with an abutment portion of a fixing frame section. When a temperature of an actuator is equal to or lower than a predetermined temperature, a biasing force of the biasing spring surpasses a force generated in the actuator, and thus the lens unit is not moved. When the actuator is heated up to a temperature equal to or higher than the predetermined temperature, the lens unit is continuously moved in the +Z direction. Thereby, movement of a lens due to a change of an environmental temperature can be prevented.
