PURPOSE:To eliminate the play between the channel selection member, moving plate and unit frame, by moving the plate through butting a pair of butted sections provided with the channel selection member to a pair of butted sections opposing to them. CONSTITUTION:The channel selection member A providing a pair of butted sections 6, 6' which are displaced and located at a remote position and the moving member C interlocked with the tuning element are mounted to the unit frame B in crossing. The channel selection member A is provided with a pair of butted sections 6, 6' acting to move the moving member C at its operation and the cushioned members 17, 17'. When either of the butted sections 6, 6' is butted to the cushioned sections 6, 6' opposing, unidirectional action is given to move member C and when it butted to the cushioned members 17, 17' of the butted sections 6, 6', reverse componential force is generated at each butted point. Thus, the play between the channel selection member, moving member and unit frame can be reduced. |
