Here, when the operation members 33 and 34 are slid upward, as shown in FIG. 6C, the flange 32C of the lock member 32 connected to the operation members 33 and 34 slides upward, and the flange 32C is the receiving portion. The lock member 32 is fitted into the receiving member 45 by being fitted into the groove 44 </ b> A of the main body 44. Accordingly, since the screen door 12 can be fixed to the frame body 11, it is possible to prevent the screen door 12 from being detached from the frame body 11 due to a strong wind or the like.

  According to the present embodiment, the sliding door type screen door 12 is arranged on the frame 11 of the four-sided frame attached to the opening of the frame, and the lock member 32 is arranged on the vertical rod 12d of the screen door 12. Operating members 33 and 34 are provided on the face 12d2 and 12d3 of the vertical rod 12d and the operating members 33 and 34 are slid in a state where the screen door 12 is closed to lock the locking member. Since the receiving member 45 that engages or disengages 32 is attached to the vertical frame 11c of the frame body 11, the screen door 12 can be fixed to the vertical frame 11, and the screen door 12 can be detached from the frame body 11 due to strong wind or the like. Can be prevented. Further, according to the present embodiment, since the lock member 32 is operated by sliding up and down, the shaft portion 32B and the flange 32C of the lock member 32 do not protrude greatly from the vertical rod 12d during the slide operation. Since the shaft portion 32B and the flange 32C are hardly exposed to the outside, the design of the screen door 12 can be improved.

  Moreover, according to this embodiment, since the lock member 32 is accommodated in the vertical hook 12d, this lock member is not exposed outside the vertical hook 12d. According to this, since the variation of the design of the downarm 12d increases compared with the conventional structure, the designability can be improved.

  In addition, according to the present embodiment, the lock member 32 includes the locking portion 51 that is locked to the vertical rod 12d in a state in which the lock member 32 is fitted to the receiving member 45. It is possible to prevent the lock from being released by dropping downward due to gravity. Further, according to the present embodiment, the receiving member 45 includes the holding portion 43A that holds the vertical frame 11c, and the holding portion 43A has a claw portion 43A1 that fits into the groove 42A formed in the vertical frame 11c. Therefore, the receiving member 45 can be firmly fixed to the vertical frame 11c. Therefore, by engaging the lock member 32 of the screen door 12 with the receiving member 45, the screen door 12 can be fixed to the vertical frame 11, and the screen door 12 can be prevented from being detached from the frame body 11 due to strong wind or the like. .

However, the present invention is not limited to this, and the screen door 12 can also be applied to a structure in which the screen door 12 is arranged in the frame body 11. In this case, as shown in FIG. 7, since the vertical rod 12d of the screen door 12 comes into contact with the frame piece 42, the lock member 32 cannot be accommodated in the vertical rod 12d. For this reason, it is good also as a structure which accommodates the locking member 32 in the case main body (case part) 90 on the outdoor side of the vertical shaft 12d. In this configuration, the case main body 90 extends to the outdoor side. However, since the case main body 90 is not exposed to the indoor side, the design variation of the vertical rod 12d is increased as compared with the conventional configuration. It is possible to improve the performance.

  Further, in the present embodiment, the configuration in which the lock member 32 is disposed on one vertical rod 12d of the screen door 12 has been described. However, the present invention is not limited to this, and the other vertical rod 12c or both vertical rods 12c and 12d The lock member 32 may be accommodated and the receiving member 45 may be attached to the vertical frames 11c and 11d corresponding to the vertical rods 12c and 12d. In the present embodiment, the configuration in which the flange 32C is formed in the lock member 32 and the groove portion 44A is formed in the receiving portion main body 44 has been described. However, the flange 32C and the groove portion 44 may be formed in reverse. Moreover, although the support member 43 demonstrated the structure provided with the clamping part 43A which clamps the vertical frame 11c, it is not restricted to this, For example, it is good also as a structure screwed to the vertical frame 11c.
