PURPOSE:To make the resetting of a delivery posture unnecessary after the finish of an internal examination, by revolving a backrest part and a crotch receiving part in conjunction with the first and second drive means in such a state that the angle formed by both parts is held to an almost constant angle by a revolving means. CONSTITUTION:Since a backrest part and a crotch receiving part are revolved in such a state that the angle formed by both parts is held to an almost constant angle by a revolving means, for example, even when the backrest part and the crotch receiving part are revolved to revolve the whole of the body of the patient forwardly or backwardly, after the posture of a patient suitable for deliver is set, the posture of the patient is held to that set at the beginning. Therefore, it is unnecessary to reset the posture of the patient to that set at the beginning at each time when an internal examination is performed by revolving the body of the patient forwardly and backwardly. Since the angle formed by the backrest part and the crotch receiving part is held to an almost constant angle while both parts are separately revolved by a backrest part driving means and a crotch receiving part drive means, the labor for fixing both parts is avoided and the generation of the accident of the patient due to the unexpected release of the fixing of both parts can be prevented.
