<P>PROBLEM TO BE SOLVED: To efficiently cool heat generation rotary equipment being a target in a casing. <P>SOLUTION: A centrifugal fan 54 is attached to an inner plate 40b of a centrifugal clutch 40 being the heat generation rotary equipment, and an intake port 59a of the casing is arranged in the vicinity of a front face in the axial direction of the centrifugal fan 54. The centrifugal fan 54 is provided with a base plate 86 connected with the inner plate 40b of the centrifugal clutch 40, a plurality of fins 87 provided on the base plate 86, a blow-out hole 88 passing through the base plate 86 in the axial direction between arbitrary ajacent fins 87, and a guide wall 89 for guiding air directed toward an outer side in the radial direction on the base plate 86 into the blow-out hole 88. The air immediately after being introduced from the intake port 59a is blown to the centrifugal clutch 40 in a rear part through the blow-out hole 88. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
