The support side first engaging portion 31 is sandwiched between the two. Thereby, the holding member 5 holds the support side first engagement portion 31 and is fixed to the support member 2.

  In a state where the holding member 5 is fixed to the support member 2, the slit portion 9 a of the holding portion 9 is located at the tip on the opening 6 side. That is, the hollow part of the holding part 9 opens toward the opening 6 side. As shown in FIG. 3, the sheet 10 is held by the holding member 5 when the rod-like member 11 is inserted into the holding portion 9. The sheet 10 is fixed to the support member 2 via the rod-shaped member 11 and the holding member 5 and supported by the support member 2. Holding members 5 are attached to the supporting members 2 at both ends of the opening 6 in the width direction, and both ends of the sheet 10 are supported by the holding members 5. The rod-shaped member 11 can be slid from the end of the holding part 9 and inserted into the hollow part. The slit part 9a is expanded and inserted into the hollow part of the holding part 9 through the slit part 9a. It is also possible.

  For example, even if the user attaches the holding member 5 to the support member 2 after inserting the rod-like member 11 of the sheet 10 into the holding portion 9, the user can attach the holding member 5 to the support member 2. You may make it insert the rod-shaped member 11 of the sheet | seat 10 in the holding | maintenance part 9. FIG. The user first attaches the holding member 5 to the support member 2 after holding the sheet 10 on the holding member 5 according to the situation at the site, or attaches the holding member 5 to the support member 2 and then attaches the sheet 10 to the support member 2. It can also be held by the holding member 5. Therefore, according to the waterproof device 1-1 of the opening part which concerns on this embodiment, the workability | operativity at the time of installation can be improved.

  When water comes from the outside in a state where both ends of the sheet 10 are supported by the support member 2, water pressure is applied to the sheet 10 as shown in FIG. 3. At that time, the sheet 10 contacts the corner portion 24 of the support member 2. The sheet 10 is pressed toward the support member 2 and the opening / closing body 4 by water pressure, and comes into close contact with the support member 2 and the opening / closing body 4. The seat 10 closes the gap between the support member 2 and the opening / closing body 4 and suppresses the intrusion of water into the room. In addition, the seat 10 closes a gap between the door 41 and the door 42 and suppresses intrusion of water into the room. Further, the sheet 10 is pressed toward the floor surface 7 by water pressure. Thereby, the sheet | seat 10 block | closes the clearance gap between the opening / closing body 4 and the floor surface 7, and the clearance gap between the supporting member 2 and the floor surface 7, and suppresses the penetration | invasion of water to indoors. In addition, you may make it install a pressing member on the lower end part 10a of the sheet | seat 10. FIG. The pressing member is a member that presses the lower end portion 10a toward the floor surface 7 by its own weight. When the pressing member presses the lower end portion 10a of the sheet 10 toward the floor surface 7, the flooding between the sheet 10 and the floor surface 7 can be more reliably suppressed. The shape of the pressing member can be, for example, a flat plate shape.

  Moreover, in the waterproof device 1-1 of the opening part which concerns on this embodiment, when the water pressure is applied to the sheet | seat 10, the holding member 5 will remove | deviate from the supporting member 2, as demonstrated with reference to FIG. The engaging portions 30 and 50 are configured so as to be able to be suppressed.

  When water pressure is applied to the sheet 10, as shown by an arrow Y <b> 1 in FIG. 4, a force that pulls toward the opening 6 side acts on the sheet 10. Due to this force, the holding side first engagement portion 52 is subjected to a force in a direction to be inserted into the first groove portion 33 as indicated by an arrow Y2. On the other hand, as shown by the arrow Y3, a force in the direction pulled out from the second groove portion 34 acts on the holding-side second engagement portion 53. Therefore, it is desirable that the holding-side second engagement portion 53 can be prevented from being detached from the support-side second engagement portion 32 when the holding member 5 holds the sheet 10.

  In the waterproof device 1-1 for an opening according to the present embodiment, the holding-side second engagement portion 53 and the support-side second engagement portion 32 are deeply engaged. As shown in FIG. 4, the holding side second engaging portion 53 and the supporting side second engaging portion with respect to the meshing depth W1 between the holding side first engaging portion 52 and the supporting side first engaging portion 31. The meshing depth W2 with 32 is large. The meshing depth W1 is the width of the overlap between the protrusion 54 and the support-side first engagement portion 31 when the support-side first engagement portion 31 and the holding-side first engagement portion 52 are engaged. is there. The meshing depth W <b> 2 is a width of overlap between the distal end portion 55 and the protruding portion 39 when the support-side second engagement portion 32 and the holding-side second engagement portion 53 are engaged.

  Since the engagement depth W <b> 2 is larger than the engagement depth W <b> 1, the distal end portion 55 of the holding side second engagement portion 53 is deeply engaged with the support side second engagement portion 32. Accordingly, the holding-side second engagement portion 53 is prevented from coming out of the second groove portion 34 when the holding member 5 holds the sheet 10. Further, since the meshing depth W1 is shallower than the meshing depth W2, the force required when the holding member 5 is attached to and detached from the support member 2 is reduced. When the holding member 5 is attached to the support member 2, the holding side first engagement portion 52 is moved after the holding side second engagement portion 53 and the support side second engagement portion 32 are engaged first. If the support-side first engagement portion 31 is engaged, the holding member 5 can be engaged with the support member 2 with a small force. Further, when removing the holding member 5 from the support member 2, the holding side first engagement portion 52 is moved in the state where the holding side second engagement portion 53 and the support side second engagement portion 32 are engaged. If it pulls out from the one groove part 33, the holding member 5 can be removed from the support member 2 with small force.

  In the waterproof device 1-1 of the opening according to the present embodiment, the holding member 5 is fixed to the outdoor side surface of the support member 2.
