Abstract
An electrical component comprises a holder having shaft holes and a plurality of rotary members each consisting of a shaft portion fitting into a respective shaft hole in the holder. Connection members formed unitarily with the rotary members each connects a rotary member to at east one other rotary members adjacent to it; and break-off portions formed on the connection member are capable of breaking easily from the rotary members when the rotary members are forced to rotate.
Claims12
An electric component comprising
- a holder having shaft holes;
- a plurality of rotary members, each consisting of a shaft portion fitting into a respective one of said shaft holes of said holder, an operation portion formed integrally with said shaft portion, and a driving portion;
- a connection member for connecting each of said rotary members to at least one other rotary member adjacent to said rotary member;
- and a break-off portion formed on said connection member, capable of breaking easily when each of said rotary members is forced to rotate;
- each of said rotary members becoming rotatable with respect to said holder when said break-off portion breaks off;
- wherein said connection member consists of a connecting portion connecting said rotary members with each other via break-off portions, and a holding portion embedded into said holder and preventing said connecting portion from falling off even when said connecting portions are broken off from said rotary members.
In an electric component having a plurality of rotatable shafts fitted rotatably within corresponding holes of a holder, said rotatable shafts each being formed of a synthetic resin material molded in place within the respective holes of said holder, the imporvement wherein said rotatable shafts are formed unitarily with connecting members molded into said holder for retention thereby and having break-off portions connecting adjacent rotatable shafts and adapted to be separated therefrom upon the initial rotation of said shafts for holding said shafts in position during assembly.
