Variable mechanism for mounting angle housed gyro-sensor and method of mounting variable mechanism for mounting angle

A vehicle navigation system comprising:

• a housing;
• a vehicle navigation system main body provided in said housing;
• a housed gyro-sensor movably supported in said housing without reference to a mounting angle of said vehicle navigation system main body, said housed gyro-sensor being supported horizontally;
• a retaining indentation fixed to said housing;
• and
• a spherical section provided on an end of an arm extended from said housed gyro-sensor, said spherical section engaged with said retaining indentation.

A vehicle navigation system comprising:

• a housing;
• a vehicle navigation system main body provided in said housing;
• a housed gyro-sensor movably supported in said housing without reference to a mounting angle of said vehicle navigation system main body, said housed gyro-sensor being supported horizontally;
• a mounting hole formed in said housing;
• and
• a rotation plate (1) mounted for rotation in said mounting hole, (2) housing said housed gyro-sensor, and (3) provided with a balancer disposed below said housed gyro-sensor.

A vehicle navigation system comprising:

• a housing;
• a vehicle navigation system main body provided in said housing;
• a housed gyro-sensor provided in said housing;
• and
• an inclination detection mechanism (1) detecting an inclination of said housed gyro-sensor and (2) correcting an output value from said housed gyro-sensor depending on an inclination of said car navigation system main body to a value corresponding to a value when said housed gyro-sensor is disposed horizontally.
