<p><P>PROBLEM TO BE SOLVED: To provide a reflector installed for easily discriminating a reflected wave from the reflector installed on another vehicle or a reflected wave from the road surface or a structure positioned on the periphery of the road. <P>SOLUTION: The reflector 2 is installed on the upper edge and on the center in the width direction on a trunk door back wall 31. Since the mounting position in the height direction of the reflector 2 is set on the upper edge on the trunk door back wall 31, the reflector 2 can be separated greatly from a structure positioned on the road surface and reflecting a millimeter wave well, Since the mounting position in the vehicle width direction of the reflector 2 is set on the center in the vehicle width direction, an average distance from a structure reflecting a millimeter wave having a possibility of existing on either of right and left both sides of the road can be set to be the longest. Resultantly, a vehicle detector 1 loaded on another vehicle can discriminate easily a reflected wave from the reflector 2 or a reflected wave from the structure. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
