PROBLEM TO BE SOLVED: To provide a cooling mechanism capable of increasing cooling capacity in a cooling structure using a fan without greatly changing the shape of a duct that guides the flow of fluid generated by the fan and without enhancing the capacity of the fan or adding other fans.SOLUTION: A cooling mechanism of a motor of the invention, which includes a fan for generating the flow of fluid for cooling a motor and a duct which is provided on the periphery of the motor and on which a flow path for guiding the flow of fluid generated by the fan is formed, cools an object by providing a plurality of holes on the duct that guides the flow of fluid generated by the rotation of the fan and branching the fluid generated by the rotation of the fan into fluid flowing through the duct and fluid flowing outside from the holes provided on the duct.SELECTED DRAWING: Figure 3 |
