  "textContent": "A venting device includes a fixed member provided with a through-hollow body, and provided with a first stepped part on an inner circumferential surface of an upper portion of the body; and a movable member inserted into and coupled to the inside of the fixed member, and provided with a plurality of venting holes; and a second stepped part on a lower outer circumferential surface facing the first stepped part; and a gap-maintaining member exerting a repulsive force between the fixed member and the movable member. The movable member is movable relative to the fixed member between a first position maintained by the repulsive force exerted by the gap-maintaining member, and a second position when an external force exceeding the repulsive force is applied. The number of venting holes in the movable member connecting with the outside in the first and second positions is different.",
