PURPOSE:To absorb the mechanical play and to increase the accuracy, by providing the moving member moving toward the direction in crossing with the channel selection member and shifting the moving member via the rotary plate turned with the operation of the chanel selection member. CONSTITUTION:The channel selection member A having the specified members 5, 5 having a pair of buffer members 6, 6' displaced each other at located position is provided at the unit frame B. Further, the moving member C controlling the variable tuning element which moves toward the crossing direction with the channel selection member A is provided. A pair of rotary members 14, 14' having the cushioned section in bufferring with the buffer 6 at the moving of the channel selection member 4 are mounted on the unit frame B. The rotary member 14 is individually linked to the moving member C and the componential force in opposite direction each other and exerted to the buffer point is generated, when either one of the buffers are butted to the cushioned part, allowing to absorb the play between the unit frame B and the channel selection member and to increase the accuracy of channel selection. |
