PURPOSE:To eliminate mechanical play, by providing two operating points exerted to the moving member moved toward crossing direction with the channel selection member by means of the slide of channel selection member and using the componential force generated at this operating point. CONSTITUTION:The channel selection member A and the moving member C interlocked with the tuning element are mounted to the unit frame B so that they move to the crossing direction. The channel selection member A is provided with a specified plate 7 having a pair of buffer members 6, 6' located and displaced at a remote position. The moving member C is provided with a pair of cushioned members 14. 14' butted with the said buffer at moving of the channel selection member A. The buffer section allows the moving member C a given direction of movement when it is butted to the cushioned section opposing each other and opposite componential force is generated to each buffer when each buffer is butted to cushioned sections opposing each other, allowing to eliminate the play between the channel selection member A, moving member C and unit frame B. |
