Claim:
A radar mount direction alignment device for aligning a transmit/receive direction of a radar device mounted on a member on which the radar device is mounted, the device comprising: a receiving section for receiving a signal transmitted from the radar device; a transmission section for transmitting a signal to the radar device; a transmission line for transmitting a signal, wherein a predetermined signal is transmitted toward the radar device after a received signal has been transmitted over the transmission line; a signal transmitting device for transmitting, toward the radar device, a signal which, when the signal transmitted from the radar device is received, behaves as if having been reflected from a reflection target disposed at a position farther from the radar device than a distance between the radar device and the radar mount direction alignment device; and a reflector which reflects a signal entered from one end of the transmission line, at the other end of the transmission line, wherein the reflected signal exits from the one end of the transmission line.
