There is provided a cooling structure of which performance for cooling ring members and brushes is enhanced. In a cooling structure applied to a slip ring device (10), the slip ring device (10) comprises ring members (11a-11c) provided to an input shaft (3) and brushes (12a-12c) contacting with these ring members (11a-11c), the input shaft (3) includes a shaft member (3a) where an external spline portion (16) is formed, and a cylindrical member (3b) that is installed over the external circumference of the shaft member (3a) so that an internal spline portion (17) formed on the cylindrical member is meshed with the external spline portion (16), and that the ring members (11a-11c) are fixed to the cylindrical member (3b); and the internal spline portion (17) is formed upon a portion of the inner circumferential surface of the cylindrical member (3b) that lies on the radially inward side of the ring members (11a-11c).
