Abstract: In a pop-up structure of the invention, an elevatable member is rotatably disposed on upper portions of a pair of front and rear poles, which is also rotatably provided on a base member. Shielding plates extend between the front and rear poles on both sides thereof. In case the elevatable member is elevated by rotating both poles, even if an elevating height of the elevatable member is high, at least a part of the space formed between the front and rear poles is covered by the shielding plates at the both sides. Therefore, the appearance at the popped-up state of the pop-up structure is improved, and there is no risk of catching foreign materials by the poles or the like when it is collapsed.
