Abstract
A wrist cover covers a wrist of a robot. The wrist includes a first wrist element, a second wrist element, and a third wrist element coupled in series and rotatable with respect to one another. The wrist cover includes: a rotating seal member that is fixed to the second wrist element, thereby sealing a ring-shaped gap between the second wrist element and the third wrist element while allowing relative rotation between the second wrist element and the third wrist element; and a flexible bag-shaped cover body that has a first opening arranged so that the first wrist element is passed therethrough, and a second opening arranged so that the third wrist element is passed therethrough. The cover body and the rotating seal member are attached with a space between a peripheral edge of the second opening and the rotating seal member being sealed over the entire periphery thereof.
