Abstract
A pop-up mechanism is formed of a base body, at least one pair of flip-flop members, each being rotatably linked to the base body at one end, and an ascending and descending member rotatably attached to the flip-flop members at the other ends. The flip-flop members have a folded state where the flip-flop members are substantially located close to the base body, and a pop-up state where the flip-flop members are turned upwardly. An urging member is attached to at least one of the flip-flop members for urging the one flip-flop member in the pop-up state, and a locking device is formed for locking the flip-flop members in the folded state. In the pop-up mechanism, at least one strut with a predetermined height is placed on an upper surface of the base body and/or a lower surface of the ascending and descending body. In the pop-up state, a tip of the strut abuts against a portion communicating with the upper surface of the base body and/or the lower surface of the ascending and descending body to hold the ascending and descending body in the pop-up state.
