PROBLEM TO BE SOLVED: To surely make a transmitted detection wave incident to a receiver even if an axial deviation is generated due to an oscillation and the like, and perform a stable distance measurement.SOLUTION: In the distance measurement device performing a transmission/reception of a detection wave between two moving objects getting close to or separating apart from each other and measuring a distance between the moving objects, two moving objects includes transmission/reception means for transmitting/receiving the detection wave and a corner reflector, respectively, and the transmission/reception means of one of the moving bodies is arranged to face the corner reflector of the other of the moving bodies. |
