<P>PROBLEM TO BE SOLVED: To provide an anti-theft device of a motorcycle capable of detecting acceleration in the right and left directions even when this anti-theft device is attached to any of an XY plane, a YZ plane, and a ZX plane of a vehicle body. <P>SOLUTION: This anti-theft device of the motorcycle is composed of a case body having mounting faces attached to the XY, YZ, and ZX planes by using the right and left directions of the vehicle body as an X-axis, the forward and backward directions as a Y-axis, and the vertical direction as a Z-axis, a substrate 16 stored in parallel with the mounting faces in the case body, and an acceleration sensor 13 mounted on the substrate 16 and having two axes crossing orthogonally to detect output of the acceleration sensor 13 having two axes crossing orthogonally and give a warning. One axis among detection axes of the acceleration sensor 13 having two axes crossing orthogonally is vertical to the substrate 16, and the other axis is parallel with the X-axis when the mounting faces are attached to the XY plane or the ZX plane. <P>COPYRIGHT: (C)2008,JPO&INPIT |
