Input device provided with strain gages

摘要

An input device has a control member having an operating part and a base part. The base part has arms and connecting parts connecting the adjacent arms. Strain gages are placed on the arms, respectively. Projections are formed on the connecting parts or a holding member for holding the control member thereon to secure spaces between the arms and the holding member to enable the arms to be strained greatly when the operating part is tilted so that the respective electrical resistances of the strain gages can be changed greatly for the slight tilting of the operating part of the control member.
