態確認装置。[Scope of Claim for Utility Model Registration] A device for confirming the proximity of an obstacle, which is installed at the rear of a vehicle and has a structure that projects two parallel beams of light that intersect at a point at a close distance, comprising: (a) a light source; (b) means for condensing the light emitted from the light source into a substantially parallel beam; (c) means arranged obliquely to the substantially parallel beam, reflecting light of a specific wavelength and reflecting light of other wavelengths; (d) a second mirror disposed obliquely with respect to the light beams of other wavelengths that have passed through the first mirror; and (e) a proximity state confirmation device, characterized in that the light beam reflected by the first mirror and the light beam reflected by the second mirror intersect at a close distance. .
