Abstract: A front defroster nozzle includes a connecting portion connected to an air conditioner at a lower side of a central portion in a vehicle width direction of a front windshield, a nozzle lower portion provided at an upper side of the connecting portion, and a nozzle upper portion provided at an upper side of the nozzle lower portion, so as to slope towards a vehicle rear side, the nozzle upper portion having a blower aperture portion that extends in the vehicle width direction and opens at an upper end portion of the nozzle upper portion and at an instrument panel, and, when viewed in a cross-section taken along a vehicle front-rear direction, a blow-out angle formed between the nozzle upper portion and the front windshield is set such that the blow-out angle at both end portions in the vehicle width direction is larger than the blow-out angle at the central portion.

Abstract: An outer mirror for a vehicle according to the technology of the present disclosure includes a mirror stay, a mirror visor, and a mirror for checking behind the vehicle. The mirror stay is provided at a vehicle body side face. The mirror visor is supported by the mirror stay and includes an opening portion at a vehicle rear side. The mirror is provided in the opening portion. In a horizontal section cut through the mirror visor, a distance between a vehicle width direction inner side face of the mirror visor and the vehicle body side face decreases toward the vehicle rear from a front end portion of the mirror visor.

Abstract: A CPU uses a simulation in which a vehicle model is made to run to calculate the amplitude of pressure variations generated on the surface of the vehicle model for each location on the vehicle model surface, and to calculate a mean surface flow velocity, which is a time average at a predetermined time of the flow rate of a fluid on the vehicle model surface, for each position on the surface of the vehicle model. The CPU also calculates an acoustic intensity for the respective locations on the vehicle model surface based on the calculated amplitude of the pressure variations and on the calculated mean surface flow velocity, and, by performing surface integration on the calculated acoustic intensities on the vehicle model surface, also calculates an acoustic power, which is the total energy of the sound emitted from the vehicle model surface.
