リツプしてなる周波数同調機構のダイヤル装置。[Scope of claim for utility model registration] A dial knob and a shaft to which the dial knob is fitted and which transmits the rotation of the knob to the rotating shaft of the variable capacitor, and either the shaft fitting part of the dial knob or the outer periphery of the shaft. It consists of a plurality of bulging protrusions provided on one side, and at least one engagement protrusion provided at a position to engage with the plurality of bulging protrusions on the other side, and the rotation shaft of the variable capacitor is located at the terminal end. When the rotation of the shaft related to the rotating shaft is stopped, the engaging protrusion intermittently slips on the surface of the bulging protrusion even if the dial knob is rotated. Frequency tuning mechanism dial device.
