<p>PURPOSE:To prevent the blockading of a running air intake port due to a piece of paper, by a method wherein a piece of paper excluding guard is provided before the running air intake port on a protecting cover, covering the outer periphery of a coil, so as to be slanted with respect to the flow direction of the running air. CONSTITUTION:A running air intake port 25, provided at the fore end of a protecting cover 14, covering a coil 10, in the running direction of a vehicle, is opened so as to be slanted somewhat downwardly with respect to the flow direction of the running air A while a dust-proof wire net 26 is extended with the same slant as the slant of the opening end face of the running air intake port 25. A guard 27 for excluding a piece of paper is arranged before the running air intake port 25 on the fore end of the protecting cover 14. The guard 27 for excluding piece of paper is constituted of rods, bent so as to have reverse L-shape like a rake, and respective hanging parts 27b are not straight and are slanted so that the lower end side thereof are slanted by an angle theta with respect to the running air A as shown in a diagram.</p> |
