Abstract
A connector pin which has a structure wherein a pin which can be moved by a spring is kept in contact with a casing by way of connecting member, an electrically conductive magnetic fluid is sustained in the casing, and the casing and the connecting member are magnetized. Owing to this structure, the connector pin is capable of extremely reducing production of metal powders in the casing and has a prolonged service life. Since the electrically conductive magnetic fluid can be sustained by magnetizing the parts composing the connector pin, no sealing member is required for sealing the electrically conductive magnetic fluid and the connector pin has a remarkably simplified structure.
