Abstract

본 발명은 회전축(21)에 경사가 생겼다고 해도 회전축(21)의 편마모나 회전변동을 방지할 수 있고, 엄격한 치수관리나 조립정도를 필요로 하지 않는 회전구동장치의 제공을 목적으로 하는 것으로, 축받이부(33)를 갖는 합성수지제의 섀시(1)와 섀시(1)의 축받이부(33)에 회전 자유롭게 지지되고, 모터(13)에서의 동력전달에 의해 회전구동되는 캡스턴(22)과 섀시(1)에 설치되고 상기 축받이부(33)에 대해 캡스턴(21)의 축방향으로 이간한 위치에서 이 캡스턴(21)을 회전 자유롭게 지지하는 지지부재(37)를 구비하고 있고, 상기 섀시(1)에 상기 축받이부(33)를 탄성적으로 변위가능하게 지지하는 변위부(46)를 일체로 설치한 것을 특징으로 하는 회전구동장치에 관한 것이다.The present invention is intended to provide a rotary drive device that can prevent uneven wear and rotational fluctuation of the rotary shaft 21 even if the inclination occurs in the rotary shaft 21, and does not require strict dimensional control or assembly accuracy. The capstan 22 and the chassis which are rotatably supported by the chassis 1 made of a synthetic resin having the part 33 and the bearing part 33 of the chassis 1, and are driven by power transmission from the motor 13. And a supporting member (37) rotatably supporting the capstan (21) at a position axially spaced from the capstan (21) with respect to the bearing (33). It relates to a rotation drive device, characterized in that integrally provided with a displacement portion 46 for supporting the bearing portion 33 so as to be elastically displaceable.
