Abstract

See full text

A waterproof driving shaft includes an inner tubular member defining an accommodation space and extending along an axis, an electrical driving unit disposed in the accommodation space to actuate a movement of a moving shaft member along the axis relative to the inner tubular member. A shield unit is securely connected with the moving shaft member and seals the accommodation space to prevent moisture and humidity from entering the inner tubular member so as to prolong the service life of the driving unit.
