<p>PROBLEM TO BE SOLVED: To provide a rotary machine for a vehicle which can effectively separate dust from cooling air without causing a reduction in a ventilation area due to clogging of a dust removal filter, can maintain high cooling performance and has excellent maintenance performance.SOLUTION: A rotary machine comprises: a main motor to drive a vehicle; an electric blower which generates cooling air; a ventilation duct; a flexible air duct which communicates the ventilation duct with a cooling air intake port of the main motor; and a separation filter which introduces the cooling air into the main motor while separating dust in the cooling air therefrom. The separation filter has: an upper cooling air guide plate which is formed in a manner that outwardly protrudes toward the ventilation duct to guide the cooling air to an inner surface side of the flexible air duct; and a dust accumulation section which is formed along the inner surface side of the flexible air duct to accumulate the dust in the cooling air guided by the upper cooling air guide plate.</p> |
