Claim:
1. A snoring prevention device comprising: an upper jaw mounting frame having an upper tooth insertion groove, configured for upper teeth to be inserted therein and configured to be mounted on an upper jaw; a lower jaw mounting frame having a lower tooth insertion groove, configured for lower teeth to be inserted therein and configured to be mounted on a lower jaw; and a lower jaw advance unit including a push rod provided at a center of an upper and inner side of the upper jaw mounting frame such that the lower jaw is advanced by pushing the lower jaw mounting frame forward when the upper jaw and the lower jaw are closed and a section to be pushed provided at a center of the lower jaw mounting frame such that the section to be pushed is pushed forward by the push rod when the upper jaw and the lower jaw are closed, wherein the push rod is installed at the center of the upper and inner side of the upper jaw mounting frame in an inclined manner such that a front end of the push rod protrudes downward from the center of the upper jaw mounting frame, an installation section is formed at the center of the inner side of the upper jaw mounting frame, such that the push rod is installed, and the section to be pushed is disposed at a center of an inner side of the lower jaw mounting frame, a first inclined surface is formed at the front end of the push rod to be inclined downward from an upper portion toward the inside of a mouth, and a second inclined surface is formed at the section to be pushed to be inclined upward from a lower portion toward the outside of the mouth to come in sliding contact with the first inclined surface during a process of closing the upper jaw and the lower jaw, first serrations and second serrations are formed to be meshed with each other, and provided at the first inclined surface and the second inclined surface to allow relative sliding between the first inclined surface and the second inclined surface in a direction in which the upper jaw and the lower jaw are closed, and restrict relative sliding between the first inclined surface and the second inclined surface in a direction in which the upper jaw and the lower jaw are opened, the first serration is formed on the first inclined surface of the push rod to inclinedly protrude upward and toward the outside of the mouth, and the second serration is formed on the second inclined surface of the lower jaw mounting frame to inclinedly protrude downward and toward the inside of the mouth to restrict an opening operation between the first inclined surface and the second inclined surface before a wearer intentionally further pushes the lower jaw forward in a state in which the first serrations and the second serrations are meshed with each other, and the first and second serrations are formed to form a plurality of rows at the first and second inclined surfaces to adjust an advance level of the lower jaw according to a closing level between the upper jaw and the lower jaw.
