PURPOSE: To make a medical equipment be compactly configured, reduce the installation space, and facilitate the installation by providing an air filter at the position beside the medical chair and by mounting a support to which a medical equipment bearer, etc., is attached utilizing the air filter.

CONSTITUTION: Above a base 2a of a medical chair 2 which has functions of overturning, inversion, and elevation, an air filter 3 which incorporates a sterilizer is installed beside the medical chair 2, and a support 7 is mounted beside the air filter 3. A mouth washer equipment 4 is fixed to the support 7 through a fixture 4a, and a medical equipment bearer 5 which bears various medical equipment is rotatablly attached to the support through a rotational metal fitting 5a. Above the support 7, a shadow-less light 6 is attached through a metal fitting 6a so that the shadow-less light can freely move vertically and horizontally. Since the air filter 3 is arranged beside the medical chair in combination with the mouth washer equipment 4, medical equipment bearer 5, etc., the whole medical equipment can be compact and the installation space can be saved.
