  • Patent number: 9474980
    Abstract: A controller cover includes a main body portion attached to an outer surface of a controller, and the main body portion includes a contacted portion where a contacted inner surface is in contact with the outer surface of the controller and a non-contacted portion where a non-contacted inner surface is not in contact with the outer surface of the controller. Elastic deforming protrusions are formed on the non-contacted inner surface. When the controller attached with the cover interferes with other thing, and the non-contacted portion of the cover is subjected to shock, the elastic deforming protrusion of the non-contacted portion is deformed to ease the shock, so that the controller and the interfering other thing are protected.
