Claims

[Scope of utility model registration request]

A fine adjustment shaft inserted into the main shaft, a tuning knob of the fine adjustment shaft attached to one end of the fine adjustment shaft, and a bearing that supports the main shaft with a predetermined gap intentionally provided between the main shaft. , a means for crimping a plurality of steel balls to the fine movement shaft and the bearing, a main shaft tuning knob attached to one end of the main shaft, a main shaft tuning knob, and a gap between the main shaft tuning knob and the case. A tuning mechanism comprising a spacer interposed in the main shaft, and a tuning means that is directly driven when the tuning knob of the main shaft is turned, and is decelerated and driven when the tuning knob of the fine movement shaft is turned.
