An overturn detection device includes a housing including four or more display windows, a back-forth direction detector installed on a first position of the housing and displaying a position of a first detection member in a first display part, and a left-right direction detector installed on a second position of the housing and displaying a position of a second detection member in a second display part. Further, the installation positions of the back-forth direction detector and the left-right direction detector in the first and the second positions are not externally and visually recognizable, and at least a part of the first and the second display parts are displayed through the four or more display windows as pattern data.
