A viewing object retention device allows a viewing object to be arranged at an optimum position and enables an angle of the object to be adjusted so as to accord with a direction of a face of a viewer. The device (11) includes a fixed base part (12), an arm part (13) one end portion of which is turnably joined to the base part (12), and the other end portion of which extends along an axis line from this joining point toward a space above the viewer (A), a viewing object retention part (16) located at the other end portion of the arm part (13) to retain the object (14), and a revolving mechanism (15) that displaces the retention part (16) angularly to the axis line with the turning of the arm part (13) with the joining point.
