[0060] (Effects of the opening device of this embodiment) In the opening device of this embodiment, the auxiliary frame material 115 is attached using the attachment groove portion 111c for attaching the airtight material to the upper frame material 111, so there is no need to form a new structure for attaching the auxiliary frame material 115, and this prevents the processing from becoming complicated.

[0061] In the opening device of this embodiment, when the engagement portion 115b of the auxiliary frame material 115 is engaged with the mounting groove portion 111c of the upper frame material 111, a rotation limiting member 117 is arranged on the inner side of the engagement portion 115b, between the upper frame material main body portion 111a of the upper frame material 111 and the abutment piece 115c of the auxiliary frame material 115, and the abutment piece 115c of the auxiliary frame material 115 abuts against the rotation limiting member 117, thereby restricting the counterclockwise rotation of the auxiliary frame material 115 around the engagement portion 115b as an axis, thereby preventing the auxiliary frame material 115 from coming off and being damaged.

[0062] In the opening device of this embodiment, when the engagement portion 115b of the auxiliary frame material 115 is engaged with the mounting groove portion 111c of the upper frame material 111, the upper end of the protrusion 115d of the auxiliary frame material 115 abuts against the upper frame material 111 on the outer periphery of the engagement portion 115b, thereby increasing the rigidity of the entire upper frame and restricting the auxiliary frame material 115 from rotating clockwise around the engagement portion 115b as an axis, thereby opening up the panel opening and preventing the panel from falling.

[0063] (Attachment structure of auxiliary frame material for the lower frame when configuring a fixed window) The structure for attaching the auxiliary frame member 125 to the lower frame member 121 of the opening device of this embodiment will now be described in detail. In addition, the auxiliary frame material 125 of the lower frame 12 in this embodiment is a component that is attached to the lower frame material 121 to form the panel opening when the window is used as a fixed window.

[0064] As shown in Figure 9, the auxiliary frame material 125 of the lower frame 12 of the opening device of this embodiment has a projection wall portion 125a, a hollow main body portion 125b provided on the inner side of the projection wall portion 125a, and a front wall portion 125c that extends from the outdoor side of the main body portion 125b toward the outside and then extends in an inward direction.

[0065] The auxiliary frame material 125 has a groove-shaped first engagement portion 125d that opens toward the room and is recessed toward the outside of the room (prospecting direction) at the outdoor end of the projected wall portion 125a, and a groove-shaped second engagement portion 125e that opens downward and is recessed in the inward direction (prospecting direction) is provided along the longitudinal direction at a position spaced from the first engagement portion 125d of the projected wall portion 125a, specifically at the indoor side portion of the projected wall portion 125a.

[0066] The lower frame material 121 of the lower frame 12 to which the auxiliary frame material 125 is attached has a first engaged portion 121c that protrudes toward the outside of the room (prospect direction) on the inner side of the lower frame material main body portion 121a along the longitudinal direction, and a second engaged portion 121d that protrudes toward the inside of the room (prospect direction) on a position spaced apart from the first engaged portion 121c in the prospective direction, specifically on the inner surface of the room side of the lower frame material main body portion 121a, along the longitudinal direction.

[0067] As shown in Figure 10(a), the auxiliary frame material 125 engages the first engaging portion 125d with the first engaged portion 121c of the lower frame material 121 from the outside of the room, and by rotating it clockwise around the engaged first engaging portion 125d as an axis, the second engaging portion 125e engages with the second engaged portion 121d of the lower frame material 121 from above, and the auxiliary frame material 125 is placed on the inner surface of the lower frame material 121.

[0068] As shown in Figure 10(b), the auxiliary frame material 125 placed on the inner surface of the lower frame material 121 is prevented from moving in the vertical direction (viewing direction) by the engagement between the first engaging portion 125d and the first engaged portion 121c, and is prevented from moving in the indoor / outdoor direction (viewing direction) by the engagement between the second engaging portion 125e and the second engaged portion 121d.

[0069] The auxiliary frame material 125 is placed on the inner surface of the lower frame material 121 and is attached to the lower frame material 121 by inserting a screw (fixing means) b1 from the inner side between the first engaging portion 125d engaged with the first engaged portion 121c of the lower frame material 121 and the second engaging portion 125e engaged with the second engaged portion 121d of the lower frame material 121, and the panel opening is formed by the front wall portion 125c of the auxiliary frame material 125 and the front wall portion 124c of the resin lower member 124.

[0070] (Effects of the opening device of this embodiment) In the opening device of this embodiment, the auxiliary frame material 135 is placed on the lower frame material 121 with the auxiliary frame material 135 engaged with an engaging portion that restricts movement in the finding direction and an engaging portion that restricts movement in the prospective direction, so the auxiliary frame material 125 is stably fixed, positioning is easy, and installation can be carried out easily.

[0071] In the opening device of this embodiment, the auxiliary frame material 125 is engaged with the frame material at two engagement parts that engage in the forward and backward directions, and is then fixed between these engagement parts by fixing means b1.This makes it less likely for positional deviation to occur when fixed by the fixing means b1, making installation easier and reducing the number of fixing points.

[0072] (Attachment structure of vertical frame auxiliary frame material when configuring a fixed window) The structure for attaching the auxiliary frame member 135 to the vertical window frame member 131 in this embodiment will be described in detail. In addition, the auxiliary frame material 135 of the vertical frame 13 in this embodiment is a component that is attached to the vertical frame material 131 to form the panel opening when the window is used as a fixed window, and is attached to the vertical frame material 131 by utilizing the protruding piece 131c provided on the vertical frame material 131 to be close to the vertical frame 23 of the shoji screen and to airtightly seal the gap.

[0073] As shown in Figure 11(a), the auxiliary frame material 135 of the opening device of this embodiment has a projected wall portion 135a, an indoor side piece 135b extending from the indoor side end of the projected wall portion 135a in the outer circumferential direction, an engaging piece 135c extending from the middle portion in the projected direction of the projected wall portion 135a in the outer circumferential direction, and a protruding piece 135d extending from the outdoor side end of the projected wall portion 135a in the outer circumferential direction, and a press edge mounting groove 135e is provided on the outdoor side inner circumferential surface of the projected wall portion 135a. The auxiliary frame member 135 is provided with an engaged portion 135f recessed toward the outside of the room (in the prospective direction) at a portion of the engaging piece 135c facing the indoor side piece 135b.

[0074] The vertical frame material 131 of the opening device of this embodiment has a projected wall portion 131a arranged on the inner surface of the building opening, and a protruding piece 131c protruding inward from the outdoor inner surface of the projected wall portion 131a, and an engaging portion 131d protruding toward the outdoor side (projecting direction) is provided at the inner end of the protruding piece 131c.
