    Abstract: A posture maintaining device for a 360° camera according to an embodiment of the present invention may comprise: a first correcting portion comprising a seating portion, on which a camera having a 360° view angle is seated, the first correcting portion being able to make a rotational movement about a first direction; a second correcting portion arranged on one side of the first correcting portion to be able to make a rotational movement about a second direction, which is different from the first direction; a third correcting portion arranged on the lower end of the second correcting portion to be able to make a rotational movement about a third direction, which is different from the first or second direction; and a counterbalance connected to the first correcting portion and configured to guide the camera so as to remain horizontal. A posture maintaining device for a 360° camera according to an embodiment of the present invention corrects the inclination in real time when images are taken through a camera having a 360° view angle, making it possible to implement pictures or moving images without vibration. Moreover, when images are taken through a camera having a 360° view angle, a gimbal with minimized image blocking is implemented, making it possible to obtain images with minimized interference.
