GEAR MEMBER FOR WINDSHIELD WIPER DEVICE

摘要

A linkage member of a windscreen wiper drive system such as crank 10 comprises a metallic rod 11 provided with a plastics coating 20 for protection against corrosion, the coating having been applied by an injection moulding process. Ball pin 15 may be formed by an injection moulding technique at the same time as the coating is produced. In modifications, a bearing sleeve (32, Figures) or ball socket (43, Figure 7) may also be formed by injection moulding at the opposite end of the crank to the end on which the ball pin is formed.
