Fastening device for pivotally fastening of a pulley

摘要

The pulley guides a driving cable in a power window device of a motor vehicle. The fastening device comprises a fastening member extending through said pulley and a threaded shaft extending through said fastening member for attaching the rail of the power window device with said pulley to the vehicle door. At least one end of said shaft is adapted to be deformed in such a way that after being subjected to a compressive force said pulley is axially fixed, but free of rotating, relative to the rail of the power window device. The threaded shaft has a tapered end to be fitted inside said fastening member, which is also shaped as having a complementary tapered configuration.

The invention provides a more effective and cost effective solution with regard to conventional rivet-and-sleeve solutions for securing the pulley to the rail of a power window device.
