The movement of the opening / closing body 21 in the opening direction is restricted.

  When the opening 2 is closed, the outdoor space 3 and the indoor space 4 are communicated with each other by the plurality of small holes 30 of the opening / closing member constituting member 27, so that, for example, wind or light is transmitted from the outdoor space 3. It can be taken into the indoor space 4, and rattling of the opening / closing body 21 due to wind pressure can be suppressed.

  Further, when the opening 2 is closed, for example, a suspicious person cannot see the operation unit 50 of the locking means 51 in the indoor space 4 from the outdoor space 3, and thus knows the position of the operation unit 50. In addition, it is impossible to operate the operating portion 50 from the small hole 30 of the opening / closing body constituting member 27 with holes.

  Thus, according to the opening / closing device 1, the opening / closing body 21 is a blind-opening non-opening / closing body constituting member that visually shields the operation section 50 so that the operation section 50 of the locking means 51 cannot be seen from the outdoor space 3. 28, the operation part 50 of the locking means 51 cannot be seen from the outdoor space 4, and the operation part 50 cannot be operated from the small hole 30. Therefore, the locking means by a suspicious person or the like from the outdoor space 3 51 can be unlocked and crime prevention is good.

  In addition, since the baseboard part 24 that has been used conventionally can be used as it is by using the holeless opening / closing member constituting member 28, it is processed in comparison with the case of changing the type of the baseboard part 24, etc. Manufacturing costs including costs, etc. can be reduced, no blindfold dedicated member is required, and the number of parts is not increased.

  Further, since the small hole 30 of the opening / closing body constituting member 27 is not formed in a portion of the main body plate portion 31 inserted into the guide body 6, the main body plate portion 31 is moved when the open / close body 21 is moved. Therefore, the sound-absorbing member 11 is not scraped off at the periphery of the small hole 30, wear of the sound-absorbing member 11 can be prevented, and durability of the sound-deadening member 11 can be maintained. The perforated opening / closing member constituting member (punching slat) 27 is formed, for example, by cutting a plate member into a predetermined length and then punching the portion excluding both ends in the longitudinal direction of the cut plate member of the predetermined length. After that, the retaining member 36 is attached to both end portions that are not punched and manufactured.

  In the above embodiment, the structure in which the opening / closing body 21 has only one holeless opening / closing body constituting member 28 has been described. However, for example, the opening / closing body 21 is constituted by the holeless opening / closing body constituting member 28 from the bottom to the second. In this manner, the opening / closing body 21 may have only two perforated opening / closing body constituting members 28.

The operation part 50 of the locking means 51 cannot be seen from the outdoor space 4, and the operation part 50 cannot be operated from the small hole 30. Therefore, the suspicious part from the outdoor space 3 is not reduced without reducing the aperture ratio of the small hole 30. The unlocking of the locking means 51 by a person or the like can be prevented, and the same operational effects as the first embodiment can be achieved, such as good crime prevention.

  Further, since the blindfold member 61 is rotatably attached to the opening / closing member constituting member 27 directly above the skirting board 24, the wind from the outdoor space 3 passes through the small hole 30 and the space 70. After the blindfold member 61 is rotated to the indoor space 4 side, it smoothly flows into the indoor space 4 and sufficient ventilation can be secured. In this case, the free end portion 62 of the blindfold member 61 is used as the operation portion. Since the blindfold member 61 does not rotate more than necessary by coming into contact with 50, the blindfold function of the blindfold member 61 is maintained.

  In the above-described embodiment, the configuration in which the blindfold member 61 is attached only to the lowest holed opening / closing member constituting member 27 has been described. For example, the second lowest holed opening / closing member constituting member from the bottom is used. A configuration in which a blindfold member 61 is attached to 27 may be used.
