PROBLEM TO BE SOLVED: To adjust a mounting depth of a gas valve 5 and to simplify the mounting work by reducing the number of components in a mounting structure of the gas valve installed at a back side of a wall plate 3 through a plate frame 1. SOLUTION: The plate frame 1 is composed of a front frame body 10 fixed to a surface of the wall plate 3, projecting pieces 11, 12 extended from upper and lower inner peripheral sides of the front frame body 10 to the back side of the wall face 3, and a case body 13 opened at its front side, connected with connection end parts 11a, 11b, 12a, 12b of the projecting pieces 11, 12, and accommodating the gas valve 5. The connection end parts 11a, 11b, 12a, 12b constitute a group of connection end parts mounted on point-symmetric positions to a center of a plug cylinder, extension lengths from a basic end part, of the projecting pieces 11, 12 are same as each other with respect to the projecting pieces of the point-symmetric position, and different from each other with respect to the projecting pieces adjacent to each other. The front opening end of the case body 13 is provided with a plurality of flange pieces 13a - 13f capable of being mounted on any one of the pair of connection end parts 11a, 12a, or 11b, 12b of the group of connection end parts.
