ABSTRACT:
In an oscillator having a frame, a variable capacitor mounted in the frame and having a rotor and a stator, the rotor having a rotor shaft rotatably supported on the frame, a rotor shaft support mechanism comprises: two sets of rotor shaft support portions provided in the frame, one of the two sets of rotor support portions being formed in the opposing side plates of the frame and being adapted to support the rotor shaft in a transverse direction, and the other one of the rotor shaft support portions being formed in the upper and lower plates of the frame and being adapted to support the rotor shaft in another vertical direction, whereby the rotor shaft can be supported by desiredly selected one of the two sets of rotor support portions.
