The shaft-shaped member 64b is a long shaft extending from the lower side to the upper side of the opening / closing device 3, and transmits the rotational force of the shaft-shaped member 64a and the rotating body 61b connected to one end side upward. Yes. And the shaft-shaped member 64c is connected to the other end side of this shaft-shaped member 64b substantially horizontally via the universal joint 64e.
According to the illustrated example, the shaft-shaped member 64 c is connected to the center side of the gear on the winding shaft 32 side that constitutes the power transmission means 33, so that it rotates integrally with the winding shaft 32. Yes.

  Thus, according to the opening / closing device 3 shown in FIG. 4, when water is supplied to the inflow port 61a1 in a state where the opening / closing body 10 is fully closed, the rotating body 61b is rotated by the fluid pressure, and the rotational force Is transmitted to the take-up shaft 32 by a plurality of shaft-like members 64a, 64b, 64c and universal joints 64d, 64c. Therefore, the winding shaft 32 rotates in the winding direction, and the opening / closing body 10 opens.

  In addition, according to the said opening / closing apparatus 3, although the winding shaft 32 and the rotary body 61b are always interlock | cooperated, as another example, the winding shaft 32 and the rotary body 61b are made into the inflow port 61a1. A clutch mechanism or the like may be provided so as to be interlocked only when water is supplied.

  As another example of the rotational force transmitting means, the rotational force of the rotating body arranged on the lower side of the opening / closing device is transmitted to the upper side of the opening / closing device by a power transmission mechanism including a belt and a pulley or a chain and a sprocket. A mechanism that transmits the rotational force of a rotating body arranged on the lower side of the switchgear to the upper side of the switchgear by a plurality of gears, a mechanism that appropriately combines these mechanisms, and the like It is also possible to do.

  Moreover, the structure which automatically closes the opening-closing body 10 at the time of emergency, such as a fire, operates the automatic closing device which is not illustrated according to a disaster prevention signal, for example, and performs the release operation of the brake mechanism 42 of the opening / closing machine 40 by this automatic closing device. Then, the opening / closing body 10 may be closed by its own weight. As another example, the opening / closing body 10 can be electrically closed according to the disaster prevention signal.

  Moreover, according to the said embodiment, although the rotary body 61b is rotated with the pressure of the water which flows in into the inflow port 61a1, as an other example, water other than water, such as air and oil, is provided in the inflow part 61.
