Abstract
A headgear frame comprises: a cylindrical receiving frame adapted to be fitted in a headgear; and a holding band adapted to be wound on the outer side of the headgear for clamping the headgear between itself and the receiving frame. At least one of one end and the other end of the holding band is hinged or hooked at a position apart from the receiving frame to the outer circumference. Push members projected toward the receiving frame are provided in at least one of the vicinities of the one end and the other end, as apart from the receiving frame, of the band edge of the holding band. Corresponding portions of the headgear when clamped are pushed and tensed by the push members so that they may not float from the receiving frame.
