  • Patent number: 10130876
    Abstract: A joystick module includes a base, a joystick body, a joystick cover and a second protruding edge. The base includes a casing and a first protruding edge. A top part of the casing has an opening. The first protruding edge is formed on a periphery of the opening of the casing. The joystick body is installed in the base. A first end of the joystick body is protruded through the opening so as to be rotated. The joystick cover is installed in the base and connected with the joystick body. In response to a rotation of the joystick body, the joystick cover is correspondingly rotated. During the rotation of the joystick body, a part of the second protruding edge is contacted with an inner surface of the casing. When the part of the second protruding edge is contacted with a part of the first protruding edge, the rotation of the joystick body is limited.
