Abstract:
1. A sealing device comprising: a pair of frames A, B each including a heating part attached thereto such that each of the heating parts are rotatable around a predetermined rotating shaft, the heating part generating heat by energization; and an engaging mechanism configured to couple the frames A, B such that the frames A, B are not separated in a direction that widens a gap between the heating parts, wherein when the frames A, B are coupled by the engaging mechanism, a thermally bondable sheet is fusion-bonded while being passed through a clearance formed between the heating parts, wherein the engaging mechanism includes an engager and a receptor, wherein the engager is provided in the frame A and includes: wherein the second rotator is biased toward the receptor by a biasing force, wherein the receptor is provided in the frame B and the second rotator is engageable to the receptor, wherein the second rotator is maintained by the biasing force in a state where the second rotator engages the receptor, and wherein when a force acting on the second rotator in a direction against the biasing force due to the rotation of the first rotator goes beyond the biasing force acting on the second rotator, the second rotator is eccentrically rotated relative to the first shaft and thereby the second rotator disengages from the receptor.
