Abstract
To provide a high speed vehicle having a nose shape which reduces a pressure gradient of a micro pressure wave and secures the capacity necessary for each of the driver's cab and the passenger's cabin and the visibility necessary for driving, a nose shape is proposed having a tip region, an intermediate region and a rear region, respectively. The change rate of the sectional area from the tip toward the rear end is maximal in the tip region and progressively decreases towards the intermediate region and the rear region.
