Further, if the holding member 30 is formed of a short member, it can be attached at a proper position in the longitudinal direction of the groove portion 21, and the number of the holding members 30 can be adjusted to enhance the attachment strength of the washroom panel 61. Since the holding member 30 is a short member, it can be used for both the vertical frame and the upper frame. Of course, the holding member 30 may be a long member that matches the washroom panel 61.

Further, since the opening frame 1 includes the cover member 40, the washroom-side end 11 of the opening frame 1 can be covered without exposing the groove 21 and the holding member 30. Since the cover member 40 is configured to be attached to the holding member 30 by pressing it, the attachment can be easily performed.

A decorative sheet may be attached to the surface of the cover member 40. Further, the cover member 40 itself may be a colored molded body, and the surface of the cover member may be painted or transferred. By doing so, the surface of the frame body 10 can be made to have the same or similar color tone or wood grain pattern, and can be made to look like a casing frame on the washroom side of the frame body 10. Of course, it goes without saying that the cover member 40 contributes not only to the purpose of improving the appearance as described above, but also to improving waterproofness (preventing entry of water from the washroom 6 to the living room 5 side).

Further, according to the opening frame 1 of the first embodiment, since the groove portion 21 is formed of the concave groove 12 provided in the frame body 10, the engaging portion 20 can be configured with a small number of members, and the configuration of the opening frame 1 is achieved. The manufacturing of the member can be simplified. As shown in FIG. 1, this opening frame 1 can be widely used in the direction of finding the end face of the washroom-side end 11 of the frame body 10 (without attaching the hinge 8a), and the hinged door 8 opens to the living room 5 side. Easy to apply to the opening 3.

Further, as shown in FIG. 5, the opening frame 1 according to the second embodiment cannot be widely used in the direction of finding the washroom-side end 11 of the frame body 10 due to the hinge 8a of the hinged door 8, and thus the frame body 10 cannot be used. It is used when it is difficult to form the groove 12 (of the first embodiment). That is, the opening frame 1 is easy to apply to the opening 3 in which the hinged door 8 opens to the side of the washroom 6 as described above.

Even in the frame body 10 in which the concave groove 12 cannot be formed in this way, the groove portion 21 can be formed by providing the notch recess 13 and attaching the L-shaped member 25 to the notch recess 13. Therefore, as described above, the engaging structure of the holding member 30 and the washroom panel 61 can be the same as that of the first embodiment.
