PURPOSE:To obtain the channel selection component having the smooth linear motion, by constituting the tuner with the rotatable specifying plate which operates together with the suppression bar and the movable plate possessing the rack and provided to the specifying plate via the rotary part bar. CONSTITUTION:Channel selection component part A consists of two arm metals 2 possessing rib 1 which rises in the length direction and along both the edges and specifying plate 5 positioned between the two metals 2 and possessing hitting part 4 of the axle pin which is free the rotate via bearing axle 3. In addition, suppression bar 6 which suppresses plate 5 when the plate is tilted and is supported by axle 3 in the free tilting way is provided along with free sliding push-button 8 containing projection part 7 to energize bar 6. In such way, component A is formed, and movable bar 9 possessing rack 10 interlocking component A is distributed orthogonally to component A along with a pair of rotary part bars 11 and 11' positioned between component A and bar 9. Thus the operation of plate 5 is transmitted to bar 9 via tooth parts 12 and 12' provided to bars 11 and 11'. As a result, the linear motion is obtained for bar 9 regardless of the displacement between bars 11 and 11'. |
