Patent attributes
A servo device for radio control fine-adjusts a linkage rod, which links the servo device and an operation unit, in an accurate positional relationship. The servo device includes a servo motor having a servo output shaft on which a serration is formed, and a servo horn having a shaft bore opened at the lower side thereof, the shaft bore having an inner wall on which an inner serration to be engaged to the servo output shaft is formed. The servo horn has a servo horn base from which the horn output shaft protrudes, the horn output shaft being above and coaxially to the shaft bore, an operation unit having a shaft bore engaging the horn output shaft, and an angular adjustment mechanism for linking the shaft bore of the operation unit to the horn output shaft so as to movably fix circumferentially and at an arbitrary angle.
