The radius of curvature RP1 of a mirror (P1) on the side of the front seat next to the driver's seat and the radius of curvature RD of a mirror (D) on the side of the driver's seat are set to satisfy a relation RP1>RD so that the image reflected in the mirror (P1) on the side of the front seat may be larger than the image reflected in the mirror (D) on the side of the driver's seat. The image reflected in the mirror (P1) on the side of the front seat is made larger by setting the radius of curvature RD of the mirror (D) on the side of the driver's seat at R620 and setting the radius of curvature RP1 of the mirror (P1) on the side of the front seat at R1000. An auxiliary mirror (P2) is provided below the mirror (P1) on the side of the front seat, the radius of curvature RP2 of the auxiliary mirror (P2) is set to satisfy a relation RP2<RD where RD is the radius of curvature of the mirror (D) on the side of the driver's seat, and a pivot is so provided that the mirror surface angle of the auxiliary mirror (P2) is variable.
