ABSTRACT:
A pointing device including a base part, an operating part supported on the base part in a rockable manner about a fulcrum, a magnet carried on the operating part, a magneto-electro transducer carried on the base part, and an elastic member arranged between the base part and the operating part to elastically push the operating part toward an initial balanced position on the base part. The elastic member is formed as a plate spring provided with a first section engageable with the base part and a second section engageable with the operating part. The second section is integrally joined to the first section and located to extend around the fulcrum. The first section of the plate spring extends annularly around the fulcrum and is fixedly supported on the base part, and the second section extends arcuately along the first section to exert a spring action.
