1. A vehicle range shift mechanism comprising:

  • a range selecting mechanism for selecting a shift range;

    a drive mechanism that is interlocked with and drives the range selecting mechanism;

    a range operating mechanism for operating a changeover valve with the driving force of the drive mechanism to change the shift range of an automatic transmission;

    a transmitting mechanism for transmitting the driving force of the drive mechanism to the range operating mechanism;

    a first range detection section that detects a shift range corresponding to an operating position of the transmitting mechanism;

    a second range detection section that detects the actual shift range as changed by the range operating mechanism;

    a judging section that judges whether or not the shift ranges detected by the first and second range detection sections are in mutual agreement; and

    a failure judging section that judges a failure of the first range detection section when the detected ranges are judged by the judging section as not in mutual agreement.
