To prevent the projection of an on-vehicle optical communication device to a windshield glass.
Opening walls 3, 4 for forming the opening part 2 of a defroster nozzle 1 are provided so as to have a vertical difference, and the position of the upper end point of the interior rear side opening wall 4 is set higher than the upper end point of the front opening wall 3 close to a windshield glass Fg and the like. According to this, an optical filter 7 is shielded from the field of view of a driver, and the projecting position of an on-vehicle optical communication device 5 to the windshield glass Fg is lowered to the lower part of the windshield glass Fg out of the field of view so as not to give a troublesome feeling to the driver. Thus, the concentration to safe confirmation of the driver can be promoted, and the design property around the interior windshield glass Fg can be kept.
