<p><P>PROBLEM TO BE SOLVED: To reduce aerodynamic noise generated when a car travels. <P>SOLUTION: A cross-sectional area of the car 31 in a horizontal direction with respect to a traveling direction has a shape which is partially different. For example, a tip end of a fall preventing plate 32 provided on a lower end of the car 31 traveling in an elevator shaft 35 is formed into a protruded shape. Thereby, when the car 31 is about to come to a hole sill 36, air flow at that time is dispersed therearound without stopping once at the tip. Thus, the air flow is suppressed to abruptly flow into a front face of the car, reducing the aerodynamic noise. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
