PURPOSE:To form a turning mechanism with high accuracy and to attain sure transmission by arranging a reception rib provided to a chassis to a variable capacitor gear of a middle gear connecting a prime mover gear and the variable capacitor gear arranged with a step so as to restrict the tilt of a shaft supporting the middle gear. CONSTITUTION:Since the titled device is constituted that the position is restricted by the reception rib 6b providing the middle gear 11 meshing with the prime mover gear 1a and the variable capacitor gear 3 arranged with a step to the chassis 6, when the variable capacitor 4 is turned up to a position stopping the internal turning, even is the load is being applied more, the reception rib 6b receives the moment stress exerted between a tuning knob 1 and the variable capacitor gear. Moreover, a flat face 11a of the middle gear 11 and the reception rib 6b are contacted, the smooth turning drive is realized. Since the chassis 6 is formed incorporatedly with the chassis 6, the distance between static shafts between the prime mover gear 1a and the middle gear 11 is realized with high accuracy. |
