Disclosed is a rotation driving device, which can be controlled accurately and which can prevent power transmission loss and damage to the device. The disclosed rotation driving device comprises: a driving force generation part for generating a rotational force; a rotational axis part combined with the driving force generation part to be rotated by a rotational force generated by the driving force generation part; a supporting frame part having the rotational axis part combined therewith to be able to rotate, and combined with a housing; a first link part combined with the rotational axis part and moving in the longitudinal direction of the rotational axis part in accordance with the rotation of the rotational axis part; and a second link part combined with a body to be rotated, which is combined with the housing to be able to rotate, in the first link part to rotate the body to be rotated while interlocking with the movement of the first link part, and having the first link part inserted thereinto to be able to move. The first link part includes: a first link body having a rotational axis combining groove part formed therein to have the rotational axis part screwed thereto; and a first link protrusion part protruding from the first link body and inserted into a combining groove part, which is formed concavely in the second link part, to be able to move. The first link protrusion part includes: a blink part formed in a spherical shape and touching the inner circumference surface of the combining groove part; and a first connection part having both end parts combined with the blink part and the first link body, respectively.

    회전 구동장치에 관한 발명이 개시된다. 개시된 회전 구동장치는, 회전력을 발생시키는 구동력발생부와, 구동력발생부에 결합되어 구동력발생부에서 발생되는 회전력에 의하여 회전되는 회전축부와, 회전축부가 회전 가능하게 결합되며, 하우징에 결합되는 지지프레임부와, 회전축부에 결합되며, 회전축부의 회전에 따라 회전축부의 길이 방향으로 이동되는 제1링크부 및 하우징에 회전 가능하게 결합되는 피회전체와 제1링크부에 결합되어, 제1링크부의 이동에 연동하여 피회전체를 회전시키며, 제1링크부가 이동 가능하게 삽입되는 제2링크부를 포함하고, 제1링크부는, 회전축결합홀부가 형성되어 회전축부가 나사 결합되는 제1링크바디 및 제1링크바디에서 돌출 형성되며, 제2링크부에 오목하게 형성되는 결합홈부에 이동 가능하게 삽입되는 제1링크돌기부를 포함하고, 제1링크돌기부는, 구 형상으로 형성되어, 결합홈부의 내주면에 접하는 볼링크부 및 양단부가 각각 볼링크부와, 제1링크바디에 결합되는 제1연결부를 포함하는 것을 특징으로 한다.
