Abstract
The present invention provides a tilt detecting device (), comprising a first tilt sensor () for detecting a tilting with respect to direction of gravity with high accuracy, a second tilt sensor () for detecting the tilting with respect to direction of gravity and for detecting the tilting with lower accuracy than that of the first tilt sensor and in a range wider than that of the first tilt sensor, wherein the first tilt sensor and the second tilt sensor are fixed relatively to each other, and the tilting is detected by the second tilt sensor by using a reference position and a detecting direction as detected by the first tilt sensor as reference.
