In the summons frame 34, the surface 346a of the contact portion 346 and the surface 349a of the extension piece 349 of the groove inner plate portion 343c are disposed on the outdoor side of the surface 396a of the resin inner plate portion 396 disposed on the opening side of the summons frame glass groove 34C. There is no need to form the resin summons frame 34B so that the surface 396a of the resin inner plate portion 396 and the surface 349a of the extension piece 349 are flush with the surface 346a of the contact portion 346. The resin frames 31B, 32B, 33B, 34B disposed around the openings of the glass grooves 31C, 32C, 33C, 34C can be easily manufactured.
[0161] As described above, the preferred embodiments according to the present disclosure have been described with reference to the accompanying drawings. Needless to say, the present disclosure is not limited to such examples. The various shapes, combinations, etc. of the constituent members shown in the above examples are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present disclosure.
[0162] (Third Embodiment) The fitting according to the third embodiment will be mainly described with reference to FIG. 12. In the sliding window 100D according to the present embodiment, the sealing members 42A and 42B are arranged apart from each other in the finding direction. In FIG. 12, the lower frame 32 portion will be described. The sealing member arranged on the lower side which is the outer side in the finding direction is defined as the first sealing member 42A. The sealing member arranged on the upper side which is the inner side in the finding direction is defined as the second sealing member 42B.
[0163] An intervening member 44 is arranged between the first sealing member 42A and the second sealing member 42B. The intervening member 44 is formed of at least one of a backup material and a bond breaker. The intervening member 44 has a function of cutting the edge between the first sealing member 42A and the second sealing member 42B.
[0164] The first sealing member 42A is sandwiched between the glass panel 40 and the groove inner plate portion 323c of the metal lower frame 32A. The first sealing member 42A is in contact with the surface 323d facing the outdoor side of the groove inner plate portion 323c. The surface 323d of the groove inner plate portion 323c corresponds to the "outdoor surface of the indoor side wall portion".
[0165] The second sealing member 42B is sandwiched between the glass panel 40 and the extension piece 377 of the resin lower frame 32B. The second sealing member 42B is in contact with the surface 377a of the extension piece 377.
[0166] The width dimension of the second sealing member 42B in the indoor-outdoor direction is larger than the width dimension of the first sealing member 42A in the indoor-outdoor direction.
[0167] The intervening member 44 is arranged between the first sealing member 42A and the second sealing member 42B. The intervening member 44 may be in contact with the first sealing member 42A and the second sealing member 42B, or may be separated from the first sealing member 42A and the second sealing member 42B. Due to the presence of the intervening member 44, the first sealing member 42A and the second sealing member 42B do not come into direct contact with each other.
[0168] The same operational effects as those of the first embodiment can be obtained. Additionally, the following operational effects can be obtained. Since the second sealing material 42B is provided inside the first sealing material 42A in the finding direction, deterioration of the first sealing material 42A can be suppressed.
[0169] Since the first sealing material 42A and the second sealing material 42B are partitioned by the intervening member 44, no shearing force generated when forming an integral seal occurs, and the first sealing material 42A can be reliably filled.
[0170] The metal frames 31A, 32A, 33A, 34A and the resin frames 31B, 32B, 33B, 34B have different linear expansion coefficients. Since sealing materials are provided for different dissimilar materials of metal and resin respectively, the durability of the first sealing material 42A and the second sealing material 42B can be enhanced.
[0171] The second sealing material 42B has a larger width in the indoor-outdoor direction than the first sealing material 42A, and furthermore, the second sealing material 42B covers the first sealing material 42A. Even if the second sealing material 42B is damaged, deterioration of the first sealing material 42A can be suppressed.
[0172] The metal frames 31A, 32A, 33A, 34A which are metal members ensure airtightness and water stoppage. When the depth of the first sealing material 42A provided in the resin frames 31B, 32B, 33B, 34B which are resin members is increased, since it is not necessary to align the joints between the vertical members and the horizontal members of the resin frame and the lines of the joints from the horizontal members to the vertical members to ensure airtightness and water stoppage, the joints can be enlarged, and the workability is good.
[0173] (Fourth Embodiment) The fitting according to the fourth embodiment will be mainly described with reference to FIGS. 13 to 16.
