Claim 22:
23. The device for alleviating obstructive sleep apnea according to claim 22, wherein the thickened portion at the upper outer surface and the thickened portion at the lower outer surface each have an oblique surface, wherein the oblique surface at the upper outer surface and the oblique surface at the lower outer surface approach each other in the upward and downward directions at a front end of the tongue fixing portion, wherein the thickened portions are adapted so that when the user's upper and lower teeth come into contact with the thickened portions, the upper teeth and the lower teeth would approach each other along the oblique surfaces at the upper and lower outer surfaces, and the thickened portions would move rearward relative to the user's teeth, thereby driving the tongue fixing portion and the user's tongue to move rearward relative to the user's teeth.
