<p>PROBLEM TO BE SOLVED: To provide a small and thin pointing device with low external force in all two-dimensional directions to be applied to a movable part in a slide system, with even displacement of an elastic part, with smooth and high operability and high reliability. SOLUTION: In this input device (pointing device) of a computer, etc., an operating part consists of a holder part 11, the movable part 13 and the elastic part 12 to connect them and a die of the elastic part in a molding step to integrate the holder part, the movable part and the elastic part is constituted by the operating part consisting of one gate (injection port). In addition, the operating part is formed by molding the holder part, the movable part and the elastic part by two-color molding method. In addition, the width of a displacement structure part as an interval between a peripheral part of the holder part and a peripheral part of the movable part to be connected by the elastic part is selected to be about 0.5 mm to about 2.0 mm and the elastic part is composed of materials with elastic hardness of about 30 degrees to about 40 degrees.</p> |
