One end is swingably attached, and the other end is a regulating arm 26 which is swingably supported by a support base 24 fixed to the tank top via a shaft 26a. The regulation means 22 is
It is not limited to the regulation arm 26 having such a configuration,
Various other modifications will occur to those skilled in the art.

Further, on the upper surface of the support frame 16,
Rail stand 30 for movably mounting the chair 4
Are fixed with bolts (not shown) or the like. In the present embodiment, the support frame 16 and the rail base 30 are described as separate bodies, but it goes without saying that the support frame 16 and the rail base 30 can be integrally manufactured. On the rail stand 30,
As can be better understood with reference to FIGS. 4 and 5, the stand of the chair 4, that is, the support shaft 4 in the shape of a rod.
In order to guide the lower end portion of A, a guide groove 32 is formed in the longitudinal direction, and the flange 4B formed on the chair support shaft 4A is guided in the longitudinal direction in a mode orthogonal to the guide groove 32, and a chair is formed. A restriction groove 34 for restricting the vertical movement of 4 is formed.

As mentioned above, the cabin chair 4 is
It has a seat portion 4C, a swingable back support portion 4D, and a support shaft 4A integrally connected to the seat portion, and a flange 4B is formed at a lower end portion of the support shaft 4A. The chair 4 is movably attached to the rail base 30 by fitting the flange 4B into the regulation groove 34 of the rail base 30 and the lower end of the support shaft 4A into the guide groove 32. Therefore, the chair 4 can move along the rail platform 30,
It can also be rotated on the spot. If necessary, the chair 4 may be provided with a lock mechanism on the flange 4B or the support shaft 4A so that the chair can be locked or unlocked by moving or rotating the chair.
