UNIT OF PREVENTING ELECTRIC CORROSION FOR WHEEL DRIVING DEVICE AND INNER ROTOR TYPE WHEEL DRIVING DEVICE

摘要

PPROBLEM TO BE SOLVED: To solve the problem of electric corrosion of a bearing supporting a rotor of an inner rotor type vehicle driving device, and to reduce manufacturing costs of a member used as a measure against the electric corrosion. PSOLUTION: There is provided a unit of preventing the electric corrosion for a wheel driving device. The unit of preventing the electric corrosion includes a contact body in electrically conduct with a motor rotor, an elastic body for pressing the contact body to a motor rotor side, and a storage body including a storage part storing the contact body and the elastic body and electrically conducted with a motor casing. All of the three parts are formed of a conductive material. There is provided a wheel driving device. The wheel driving device includes the unit of preventing the electric corrosion. One side of the unit of preventing the electric corrosion is electrically conducted with the motor rotor by the contact body, and the other side is in electrically conduct with a motor stator by the storage body.
