The present invention relates to a rotation plate fixing device for a motor operated inversion table and, more particularly, to a rotation plate fixing device for a motor operated inversion table, which is capable of preventing rocking of the rotation plate caused by a gap by being installed on both sides of a back and thus combined with a driving unit such that rotation force of the driving unit is transmitted to the back. The purpose of the present invention is to provide the rotation plate fixing device for a motor operated inversion table, which is capable of preventing rocking of the rotation plate even when the rotation plate is used for a long time by installing a separate fixing member for improving binding force between an output shaft and the rotation plate, thereby preventing a gap between the output shaft and the rotation plate. The motor operated inversion table includes supports (110) which are vertically installed at both sides of a base (100); a driving unit (D) which is embedded in a housing chamber (130) installed on the top of the supports (110), is fixed to the housing chamber (130) by a fastening member (171), and includes a deceleration unit (141) for decelerating rotary power of a driving motor (140); a back (120) which is installed on the top of the supports (110) and is configured to rotate by driving of the driving unit (D) such that a user is capable of lying on the back (120); and a foot hooking unit (160) which is installed on the bottom of the back (120) to firmly fix ankle regions of the user. The fixing device includes an output shaft (142) which outputs rotary power of the deceleration unit (142), and has a first plane portion (142b) formed on the surface of an end thereof; a fixing member (180) which includes a connecting hole (181) on which a second plane portion (182) is formed to correspond to the first plane portion (142b) such that the connecting hole (181) is connected to an end of the output shaft (142), a slit groove (183) in which the connecting hole (181) is formed to be opened, a supporting bolt (184) vertically inserted into the slit groove (183), and a female screw portion for fixing (185) formed on the circumferential surface of the connecting hole (181); and a rotation plate (121) in which a fastening hole (123) is formed to correspond to the female screw portion for fixing (185). |
