[Detailed description of the invention] The present invention relates to the invention of a arm mechanism for a push-button tuner, which is sufficiently thin at least in the area where the push-button arm is disposed, and which can be used in combination with a receiver and other parts as appropriate. To provide a arm mechanism for a push-button tuner that is suitable for smooth lock-in and lock-out operations, and also to ensure that the fixing operation of the frequency regulating member is performed without causing deviation in the set frequency. .

In a push-button tuner, if the area in which the push-button arm is installed is made thinner, it can be combined with receivers and other equipment in a compact manner, and can be installed compactly for use in vehicles and other applications, and the practical effects will be great. Hey.

そこでこのような目的で押釦腕金の板面を同調器の器面

来からそれなりの提案がなされている。
For this purpose, various proposals have been made in the past regarding thinner push-button tuners in which the plate surface of the push-button arm is parallel to the tuner's instrument base.

However, in the conventional thinned tuner, a circular hole into which the shaft support of the frequency regulating member is fitted is formed in the arm arm itself, which is parallel to the instrument base, and a cutout connected to the circular hole. This cut portion was compressed to narrow the circular hole and fix the shaft support of the frequency regulating member.

In the structure of such a conventional thinned tuner, the arm arm must have sufficient thickness to ensure strength during the push-in operation of the arm arm. The operation of fixing the frequency regulating member to narrow the formed circular hole cannot necessarily be carried out smoothly and easily.

In particular, in order to facilitate narrowing of the circular hole while ensuring strength to withstand the indentation pressure, one side of the circular hole in the cross arm must be widened and the other side must be narrowed. However, during the fixing operation, the shaft portion of the frequency determining member is clamped from only one side, and the shaft portion is slightly biased, resulting in a deviation in the frequency to be set, which is a serious drawback.

The present invention was devised after further study in view of the above-mentioned circumstances, and it makes it possible to further reduce the thickness of the thinned product as described above, and also has a preferable assembly. In addition to establishing the strength relationship and smoothing the fixing operation of the frequency regulating member,
We have succeeded in eliminating deviations in the frequency to be set due to biasing of the frequency regulating member during the fixing operation.
