[0026] The following describes the shoji stopper (shoji stopper member) 5 attached to the widthwise end of the bottom frame 12. The shoji stopper 5 abuts against the widthwise end of the shoji 2 that has moved in the opening direction, restricting the movement of the shoji 2. The shoji stopper 5 is attached to the end of the inner rail portion 44 of the bottom frame 12 opposite the door edge of the inner shoji 2B. The shoji stopper 5 is attached to the end of the outer rail portion 45 of the bottom frame 12 opposite the door edge of the outer shoji 2A.

[0027] The following describes the door stopper 5 attached to the inner rail portion 44. As shown in Fig. 5, the door stopper 5 includes a first upper panel portion 51, a door abutment plate portion 52, a rail engagement portion 53, a pair of opposing plate portions 54, a pair of restricting plate portions 55 (see Fig. 6), and a second upper panel portion (upper wall portion) 56.

[0028] The first upper panel portion 51 is formed in a plate shape. The plate surface of the first upper panel portion 51 faces the up-down direction. The first upper panel portion 51 is disposed above the widthwise end of the longitudinal inner rail portion 44b, the notch portion 44a, and the end inner rail portion 44c. The end of the first upper panel portion 51 facing the vertical frame 13 is formed with a recess 51a recessed inward. The lower end of the inner rail portion 44 of the vertical frame 13 is inserted and disposed in the recess 51a of the first upper panel portion 51.

[0029] As shown in FIG. 6 , an indoor side wall portion 511 is provided at the indoor end of the first upper panel portion 51. The indoor side wall portion 511 extends downward from the indoor end of the first upper panel portion 51. The indoor side wall portion 511 is formed in a plate shape. The plate surface of the indoor side wall portion 511 faces the indoor / outdoor direction. The indoor side wall portion 511 is positioned on the indoor side of the inner rail portion 44. The lower end of the indoor side wall portion 511 is located above the inner plate portion 42 of the lower frame 12.

[0030] An outdoor side wall portion 512 is provided at the outdoor end portion of the first upper panel portion 51. The outdoor side wall portion 512 extends downward from the indoor end portion of the first upper panel portion 51. The outdoor side wall portion 512 is formed in a plate shape. The plate surface of the outdoor side wall portion 512 faces the indoor / outdoor direction. The outdoor side wall portion 512 is disposed between the inner rail portion 44 and the outer rail portion 45. The lower end portion of the outdoor side wall portion 512 is located above the inner plate portion 42 of the lower frame 12.

[0031] As shown in Figure 5, the door abutment plate portion 52 extends downward from the inner end of the first upper panel portion 51 in the width direction of the sliding window 100. The door abutment plate portion 52 is connected to the inner end of the indoor side wall portion 511 in the width direction and the inner end of the outdoor side wall portion 512 in the width direction. The door abutment plate portion 52 is formed in a plate shape. The plate surface of the door abutment plate portion 52 faces the width direction of the sliding window 100. The door abutment plate portion 52 is capable of abutting against the end face (the surface along the indoor / outdoor direction) of the lower end of the vertical frame 23 on the joining side of the inner door 2B that has moved in the opening direction.

[0032] The shoji abutment plate portion 52 has an insertion hole 52h formed therein, which penetrates in the width direction of the sliding window 100. The insertion hole 52h has a shape corresponding to the inner rail portion 44. As shown in FIG. 4, the vicinity of the width direction end portion of the longitudinal inner rail portion 44b is disposed in the insertion hole 52h. The width direction end portion of the longitudinal inner rail portion 44b reaches into the shoji stopper 5.

[0033] As shown in Fig. 7, the rail engagement portion 53 extends downward from the first upper panel portion 51. The rail engagement portion 53 is disposed outboard in the width direction of the sliding window 100 relative to the screen abutment plate portion 52. The rail engagement portion 53 is disposed in the cutout portion 44a of the inner rail portion 44. An engagement piece 53a that protrudes inward in the width direction of the sliding window 100 is provided at the lower end portion of the rail engagement portion 53.

[0034] The engaging piece 53a of the rail engaging portion 53 is engaged with the lower end portion 445a of the intermediate inner plate portion 445 of the longitudinal inner rail portion 44b, which faces the cutout portion 44a. This restricts the upward movement of the shoji stopper 5. The engaging piece 53a of the rail engaging portion 53 is the only portion of the shoji stopper 5 that engages with the lower frame 12 and the vertical frame 13.

[0035] 5, the pair of opposing plate portions 54 extend outward in the width direction of the sliding window 100 from the edge of the indoor / outdoor end of the insertion hole 52h of the shoji abutment plate portion 52. The pair of opposing plate portions 54 are disposed opposite each other in the indoor / outdoor direction.

[0036] As shown in Fig. 6, the pair of opposing plate portions 54 are disposed outside the first inner plate portion 441 and the second inner plate portion 442 of the longitudinal inner rail portion 44b (see Fig. 5) and the end inner rail portion 44c in the indoor / outdoor direction. The surfaces 54a facing the opposing opposing plate portion 54 at the upper portion of the opposing plate portion 54 are gradually inclined toward the opposing opposing plate portion 54 as they go upward. The surfaces 54a of the opposing plate portion 54 abut against the upper portion of the first inner plate portion 441 and the upper portion of the second inner plate portion 442. The surfaces 54a of the pair of opposing plate portions 54 sandwich the upper portion of the first inner plate portion 441 and the second inner plate portion 442 in the indoor / outdoor direction, thereby suppressing rattling and movement of the shoji stopper 5 in the indoor / outdoor direction.

[0037] 7, the restricting plate portion 55 is formed in an L-shape when viewed from the indoor / outdoor direction. The restricting plate portion 55 is disposed outboard of the rail engagement portion 53 in the width direction of the sliding window 100. Between the pair of opposing plates 54, the restricting plate portion 55 is provided so as to protrude from each opposing plate portion 54 toward the opposing opposing plate portion 54. The restricting plate portion 55 has a rotation restricting piece portion (rotation restricting portion) 551 and a movement restricting piece portion 552.

[0038] The rotation restriction piece 551 is formed in a plate shape. The plate surface of the rotation restriction piece 551 faces the up-down direction. The lower surface 551d of the rotation restriction piece 551 abuts against the upper surface 444u of the inner rail support wall portions 443, 444 (in FIG. 7, the inner rail support wall portion 444 is shown) of the end inner rail portion 44c. The end surface of the lower end of the vertical frame 23 on the joining side of the inner shoji 2B that has moved in the opening direction may abut against the shoji abutment plate portion 52, generating a rotation moment that causes the shoji stopper 5 to turn the outer end portion in the width direction downward. Since the lower surface 551d of the rotation restriction piece 551 abuts against the upper surfaces 443u, 444u (see FIG. 6) of the inner rail support wall portions 443, 444 of the end inner rail portion 44c, the rotation of the shoji stopper 5 is restricted.

[0039] The movement restricting piece 552 is formed in a plate shape. The plate surface of the movement restricting piece 552 faces the width direction of the sliding window 100. The end face 552a of the movement restricting piece 552 facing the outside in the width direction of the sliding window 100 is disposed in contact with or with a slight gap against the end face 44d facing the cutout portion 44a side of the end inner rail portion 44c. The end face of the lower end of the vertical frame 23 on the joining side of the inner shoji 2B that has moved in the opening direction may come into contact with the shoji abutment plate portion 52, and the shoji stopper 5 may receive a force that moves outward in the width direction of the sliding window 100. Since the end face 552a of the movement restricting piece 552 comes into contact with the end face 44d of the end inner rail portion 44c, the movement of the shoji stopper 5 outward in the width direction of the sliding window 100 is restricted.

[0040] 5, the second upper panel portion 56 extends to the outdoor side from a lower end portion of the outdoor-side side wall portion 512. The second upper panel portion 56 is formed in a plate shape. The plate surface of the second upper panel portion 56 faces substantially in the vertical direction.

[0041] As shown in Fig. 6, the second upper panel portion 56 is disposed between the inner rail portion 44 and the outer rail portion 45 of the bottom frame 12. As shown in Fig. 8, the second upper panel portion 56 is disposed above the inner panel portion 42. The inner panel portion 42 has a water drainage hole (through hole) 42h formed near an end portion in the width direction of the sliding window 100. Condensed water on the bottom frame 12 passes downward through the water drainage hole 42h and through a flow passage (not shown) in the bottom frame 12 to be drained to the outdoors.

[0042] The second upper panel portion 56 is disposed with a space therebetween directly above the drainage hole 42h of the inner panel portion 42. The lower surface 56d of the second upper panel portion 56 is inclined upward as it approaches the outside in the width direction of the sliding window 100.

[0043] When attaching the shoji stopper 5 to the inner rail portion 44, the inner rail portion 44 of the vertical frame 13 is inserted into the recess 51a of the shoji stopper 5, and the shoji stopper 5 is moved downward from above the notch portion 44a of the inner rail portion 44. The engagement piece 53a of the rail engagement portion 53 moves downward along the end face of the longitudinal inner rail portion 44b facing the notch portion 44a, and engages with the lower end portion of the intermediate inner plate portion 445, and the shoji stopper 5 is attached to the inner rail portion 44.

[0044] A shoji stopper 5 is attached to the outer rail portion 45 of the bottom frame 12 at the opposite end in the width direction of the bottom frame 12, in an orientation symmetrical to the shoji stopper 5 attached to the inner rail portion 44 in the width direction center.

[0045] In the sliding window 100 configured in this manner, the engagement piece 53a of the rail engagement portion 53 of the shoji stopper 5 is engaged with the lower end portion 445a on the side facing the notch portion 44a in the intermediate inner plate portion 445 of the inner rail portion 44 and the intermediate outer plate portion 455 of the outer rail portion 45. This allows the shoji stopper 5 to be easily attached to the lower frame 12 since it only needs to be engaged in one place.

[0046] In the sliding window 100, when only the engagement piece 53a of the rail engagement portion 53 of the shoji stopper 5 is engaged with the lower end portion 445a of the intermediate inner plate portion 445 of the longitudinal inner rail portion 44b of the bottom frame 12, the recess 51a, the pair of opposing plate portions 54, and the pair of regulating plate portions 55 of the shoji stopper 5 are positioned in predetermined positions. This restricts the movement of the shoji stopper 5 in the up-down direction, the movement in the indoor / outdoor direction, and the movement in the width direction. In this way, since there is no need to engage the shoji stopper 5 with any portion other than the intermediate inner plate portion 445 of the bottom frame 12, the shoji stopper 5 can be attached to the bottom frame 12 even more easily.

[0047] In the sliding window 100, the end face of the lower end of the vertical frame 23 on the joining side of the door screen 2 that has moved in the opening direction may come into contact with the door screen contact plate 52, generating a moment that causes the door screen stopper 5 to point the outer end in the width direction downward. Since the lower surface 551d of the rotation restriction piece 551 comes into contact with the upper surfaces 444u of the inner rail support walls 443, 444 of the end inner rail portion 44c, the rotation of the door screen stopper 5 is restricted.

[0048] In the sliding window 100, the lower surface 56d of the second upper panel portion 56 of the sliding door stopper 5 is inclined upward toward the outside in the width direction of the sliding window 100. The height between the second upper panel portion 56 and the inner panel portion 42 of the lower frame 12 is greater on the end side (vertical frame 13 side) of the lower frame 12 in the width direction than on the center side in the width direction. .child As a result, in the unlikely event that rainwater or other water flows back from the outdoors to the indoors, the water can be guided along the slope of the underside 56d of the second upper panel portion 56 to the widthwise end side of the lower frame 12 (the vertical frame 13 side) where there is less air resistance, thereby preventing the water from leaking out to the inside of the width of the shoji stopper 5.

[0049] The shapes and combinations of the components shown in the above-described embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0050] For example, in the embodiment, the sash stopper 5 has the rotation restricting piece 551, but the present invention is not limited to this. The sash stopper 5 does not have to have the rotation restricting piece 551.

[0051] In the embodiment, the lower surface 56d of the second upper panel portion 56 of the shoji stopper 5 is inclined upward toward the outside in the width direction of the sliding window 100, but is not limited to this. The lower surface 56d of the second upper panel portion 56 may be formed along a horizontal plane. The shoji stopper 5 does not have to have the second upper panel portion 56.
