Oral lip and chin muscle rehabilitating device made of flexible material and having an annular open shape in accordance with the configuration of human oral lips. One side of the upper edge of the opening is formed with a recessed upper lip rest section extending outward and upward. One side of the lower edge of the opening is formed with a recessed lower lip rest section extending outward and downward. The upper and lower lip rest sections respectively receive therein the upper and lower lips of a user. A resilient connecting section is connected between the upper and lower lip rest sections to provide a certain resilient stretching force therefor. The oral lip and chin muscle rehabilitating device is positioned between the upper and lower lips of the user to rehabilitate and train the lip and chin muscle and recover the closing function of the lips. A resilient member is retained between the outer sides of the upper and lower lip rest sections so as to provide an auxiliary resilient stretching force between the upper and lower lip rest sections. The resilient member is replaceable so that one single rehabilitating device can be co-used with different resilient members with different resilient stretching force in accordance with different users or treatment progresses.
