PROBLEM TO BE SOLVED: To provide a slip ring device capable of facilitating cooling of a brush.SOLUTION: A slip ring device 10A has units U1 to U3 including brushes 12a to 12c contacting with ring members 11a to 11c and outer bus bars 14a to 14c having terminal parts 15a to 15c, to which electric wires 17a to 17c are connected, and connected with brush holders 13a to 13c holding the brushes 12a to 12c. The units U1 to U3 are stored in a case 8b and an insulation cover 9 is provided between the units U1 to U3 and the case 8b. A space S is provided between the insulation cover 9 and the case 8b, and heat exchange members 22, each of which is disposed in the space S protruding from the insulation cover 9, are respectively attached to the terminal parts 15a to 15c. A portion 22a of each heat exchange member 22 which protrudes from the insulation cover 9 protrudes from the insulation cover 9 toward an upstream side direction of airflow in the space S. |
