<P>PROBLEM TO BE SOLVED: To enhance heat-releasing property in a screening power transmission system for a vehicle. <P>SOLUTION: In the screening power transmission system 1 for the vehicle in which an outer periphery of an electric wire 22 is surrounded by a pipe 23 in the non-ventilation state, an outside air introduction port 43 for feeding cooling air from a fan device 50 to the inside and an air-discharge port 45 for discharging air at the inside are provided on pipe 23. Thereby, cooling air is fed from the outside air introduction port 43 into the pipe 23, is passed through the inside of the pipe 23 and is discharged from the air-discharge port 45. Accordingly, heat is hardly confined in the pipe 23. Further, the pipe 23 is arranged so as to be exposed to a wind-flowing portion accompanying with traveling of an electric automobile EV and an outer peripheral surface is cooled by the wind. <P>COPYRIGHT: (C)2007,JPO&INPIT |
