(Situation shown in Figure 5).
この結果、第一、第二のクラッチ部材2.8の凸部同士
が整合し、第二のクラッチ部材8.8を両側に固定した
扉7が、前板1から遠ざかる方向に移動出来なくなり、
滅菌容器の開口部が閉じられる。As a result, the convex portions of the first and second clutch members 2.8 are aligned with each other, and the door 7 with the second clutch members 8.8 fixed on both sides cannot be moved away from the front plate 1.
The opening of the sterile container is closed.
この状態で滅菌容器内に高圧の水蒸気を送り込んでも、

と5i17との気密保持が図られる。The airtightness between the front surface of the front plate 1 and the rear surface of the folding screen 7 is maintained by a backing attached to a groove formed on the front surface of the front plate 1. During this time, pressure gas is sent in, and the backing is pressed against the rear surface of the door 7 by the pressure of this pressure gas, so that the front plate 1
and 5i17 are kept airtight.
(発明が解決しようとする課題)
ところが、上述の様に構成され作用する圧力容器の扉装
置に於いて、従来次に述べる様な不都合を生じた。(Problems to be Solved by the Invention) However, in the pressure vessel door device constructed and operated as described above, conventional problems have occurred as described below.
即ち、従来の扉装置の場合、捩り軸9の両端にカム板1

の扉7を上昇させる為に大きな力を要する事になる。That is, in the case of a conventional door device, cam plates 1 are attached to both ends of the torsion shaft 9.
0 and the handle 12 are fixed so that the rotation of the handle 12 is directly transmitted to the cam plate 10, so it is possible to provide a large reduction ratio until the movement of the handle 12 is transmitted to the door 7. If this is not possible and the weight of the door 7 is large, a large force will be required to raise the door 7.
又、扉7を下降させる場合には、重力により扉7が落下
しようとする方向と、ハンドル12の回転により、この
扉7を8勤させようとする方向とが一致する為、ハンド
ル12が勢い良く回転する傾向となる。Furthermore, when lowering the door 7, the direction in which the door 7 is about to fall due to gravity is the same as the direction in which the door 7 is about to move eight times due to the rotation of the handle 12, so the handle 12 is moved by force. It tends to rotate well.
カム板10の外周面形状は、扉7の重力による下降圧力
により、ハンドル12が回転する事のない様な形状とさ
れてはいるが、ハンドル12を不用意に勢い良く回した
場合、扉7の下降速度が早くなり過ぎる場合がある。The shape of the outer circumferential surface of the cam plate 10 is such that the handle 12 will not rotate due to the downward pressure caused by the gravity of the door 7, but if the handle 12 is inadvertently turned vigorously, the door 7 The speed of descent may become too fast.

せられる。For example, when raising the door 7 to open and close the door 7, by rotating the handle 12 in an appropriate direction, the threaded shaft 24 screwed into the nut member 22 is rotated, as shown in FIG. The door 7 is pushed up via the roller 27, the bracket 26, and the reinforcing member 19 by the cam member 25 that is moved to the right and pivotally supported at the end of the screw shaft 24. Since the contact portion between the cam member 25 and the roller 27 draws a helical locus, the reduction ratio between the handle 12 and the Jji 17 can be made sufficiently large, and the door 7 can be raised with a light force.
