Abstract
A pointing device including a base section, an operating section shiftably supported on the base section, a magnet carried on one of the base section and the operating section, and a magneto-electro transducer carried on the other of the base section and the operating section at a location close to the magnet. The operating section includes a first part securely holding one of the magnet and the magneto-electro transducer and supported on the base section shiftably in a desired horizontal direction relative to the base section, and a second part connected to the first part and elastically biasing the first part toward a home position in a horizontal shifting range during a period when the first part is horizontally shifted along the base section. The second part of the operating section is provided integrally with a major portion substantially surrounding an entire circumference of the first part, a first connecting portion connected to the first part at one end of the major portion and a second connecting portion connected to the base section at another end of the major portion; the major portion exerting an even elastic biasing force irrespective of a shifting direction of the fi…
