  When only the rear opening door 30 is closed from the state in which both the doors 3 and 30 are opened, the rear opening door sealing member is interlocked with the closing operation of the rear opening door 30 as shown in FIGS. Only 21 rises to the sealing position. Therefore, the interior side surface of the lower part of the rear opening door 30 (the lower lid 50d) is pressed against the seal member 31 of the rear opening door sealing member 21 and the end of the seal plate 43 of the cover 41, and the lower part of the rear opening door 30. And the lower frame 2b are sealed in a watertight and airtight manner.

  Thereafter, when the front opening door 3 is also closed with the rear opening door 30 being closed, the front opening door sealing member is interlocked with the closing operation of the front opening door 3 as shown in FIGS. 20 also rises to the sealing position. Therefore, the interior side surface of the lower part of the front door 3 (lower lid 5 b) is pressed against the seal member 31 of the front door sealing member 20 and the end of the seal plate 43 of the cover 41, and the lower part of the front door 3. And the sealing member 20 are sealed in a watertight / airtight manner. At the same time, since the upper surface of the end portion of the front door sealing member 20 is brought into contact with the lower surface of the seal plate 43 of the cover 41, the gap G between the sealing members 20 and 21 is sealed in a watertight and airtight manner. Is done.

  If the rotation angle from the retracted position of the front opening door sealing member 20 to the sealing position is set slightly larger than the same rotation angle of the rear opening door sealing member 21, both sealing members 20 and 21 both rise to the sealing position, the upper surface of the end portion of the front opening door sealing member 20 is attached to the upper surface of the end portion of the rear opening door sealing member 21 of the cover 41 of the cover 41. Since it is pressed against the lower surface, the sealing performance is enhanced. At this time, the sealing members 20 and 21 are slightly elastically twisted around the longitudinal axis, so that the cover 41 is not damaged.

  According to this double door device 1, focusing on the opening / closing order of the doors 3, 30, the cover 41 is extended from the upper surface of the rear opening door sealing member 21 to the upper surface of the front opening door sealing member 20. Since the door is attached, the door-opening property of the doors 3 and 30 is not deteriorated, and the barrier-free property when the doors 3 and 30 are opened is improved. It is possible to achieve coexistence with the improvement of the water stoppage at the lower part of the doors 3 and 30.

  Another embodiment is shown in FIGS.

  Since the double door device according to this embodiment has basically the same configuration as the double door device 1 according to the previous embodiment, the same components are denoted by the same reference numerals and the description thereof is omitted. Only the differences will be described.

  The difference is that the gap Gx between the front-opening door sealing member 20 and the rear-open door sealing member 21 is set wider than the gap G in the above-described embodiment, and at the end of the rear-open door sealing member 21. Then, the eaves member 51 extending in the direction of the gap Gx is attached, and comes into contact with the eaves member 51 from below with the rotation of the sealing members 20 and 21 to the end of the front opening door sealing member 20. The contact member 52 to be obtained is attached.

  Specifically, as shown in FIG. 17, the eaves member 51 includes an insertion portion 54 that is inserted into and fixed to the hollow portion 53 at the end of the rear opening door sealing member 21, and the rear opening door sealing member 21. It has the 1st collar part 55 arrange | positioned substantially flush with the upper surface of the faceplate part 22, and the 2nd collar part 56 arrange | positioned in the inside. As shown in FIGS. 14 and 18, the contact member 52 contacts the insertion portion 58 to be inserted and fixed in the hollow portion 57 at the end of the front opening door sealing member 20 and the first flange portion 55 from below. It has the 1st contact part 59 which can contact | connect, and the 2nd contact part 61 which can contact | abut to the 2nd collar part 56 from the downward direction. The flange member 51 and the contact member 52 are made of rubber, resin, or the like having a certain degree of elasticity and flexibility.

  Also in this embodiment, there exists an effect similar to the previous embodiment fundamentally. Furthermore, in this embodiment, since the upper surface of the flange member 51 is substantially flush with the upper surface of the upper surface plate portion 22 of each sealing member 20, 21, when both the sealing members 20, 21 are collapsed to the storage position The barrier-free property is improved as compared with the previous embodiment. Further, in the present embodiment, as shown in FIG. 14, when both the sealing members 20, 21 rise to the sealing position, the gap Gx between the both sealing members 20, 21 is set to the first flange 55 and the first Since sealing is performed with the first contact portion 59 and sealing with the second flange portion 56 and the second contact portion 61 and sealing is performed twice, the sealing performance is improved as compared with the previous embodiment.
