Abstract
The present television fine tuning is constructed so that an initial rotation establishes the fine tuning state and that a continued rotation of the fine tuning shaft performs the fine tuning. For this purpose the present tuner comprises a fine tuning driving member, a rotation transmitting idler member, a plate spring for supporting the idler member and a fine tuning adjustment element. The driving member includes a fine tuning shaft, a slide gear and a slip clutch concentrically mounted on the front of the chassis around a channel selector shaft supported by the chassis. The slip clutch has a plastic collar loosely mounted around the selector shaft, and a metallic sheet member located in a gap formed between the inner surface of the plastic collar and the outer surface of the selector shaft.
