Abstract
A chuck apparatus grips a workpiece by a gripping section having a pair of chuck members. The chuck apparatus is equipped with a cover member and pressing members. The cover member includes insertion holes through which fingers of the chuck members are inserted, and seal members that surround the insertion holes and abut against the fingers. The cover member is attached to a body so as to cover base portions of the chuck members, and is elastically deformable so as to follow displacement of the chuck members. The pressing members press the seal members against the fingers.
