る。However, the above-mentioned vertical steam sterilizer has the following problems. Lid 68
The packing 70 is fitted into the concave and convex between the lid 68 and the lid 68 is completely tightened by the handle 66 with a predetermined tightening force. When the interval of the gap W between the lower surface and the upper surface 54a of the sterilizer main body 54 is equal to or less than a predetermined interval, even when pressure is applied to the packing 70 from high-pressure steam, the lid 68 and the sterilizer main body 54 are separated from each other. There is no possibility that the steam leaks out from the upper surface 54a by being shifted outward. But,
Since the tightening work of the handle 66 is manually performed,
There is variation in the tightening force and the tightening is loose.
The gap W between the lower surface of the sterilizer main body 54 and the upper surface 54a of the sterilizer main body 54 may be wider than a predetermined interval. In such a case, the packing 70 is displaced by the pressure received from the high-pressure steam, and the steam may leak from the space between the lid 68 and the upper surface 54a of the sterilizer main body 54, which is dangerous.

The guide portion 12 is formed by slightly projecting from the lower surface of the guide member. As a result, the guide portion 12 completely surrounds the entire packing 70, and its inner peripheral surface is in contact with the outer peripheral surface of the packing 70 to prevent the packing 70 from coming off the gap W.
In other words, the gap of the gap W between the lid 68 and the upper surface 54a of the sterilizer main body 54 is reduced by the guide portion 12 in a state where all or a part of the packing 70 is left inside the guide portion 12. Packing 70
Is restricted from moving outside. In this example, the entire packing 70 remains inside the guide portion 12.
Note that the cylindrical body 14 and the guide portion 12 may be integrated with the lid 68 in some cases.

ることができる。Therefore, the positional relationship between the cam 26 formed on the lower surface of the detection cylinder 28 and the operating lever 32a at the initial position is determined by taking into account the screw pitch of the screw rod 62 and the amount of tightening rotation of the handle 66. By doing so, when the screw rod 62 moves down from the initial position by a predetermined distance, the cam 26 of the detection cylinder 28 is moved to the operation lever 32a of the second limit switch 32
Can be pressed downward so that the second limit switch 32 is turned on. The distance between the arm body 56 and the upper surface 54a of the sterilizer main body 54 is such that the other end of the arm body 56 is
Since it is constant in the state of being suppressed by being fitted into 0,
An inverse relationship is established between the amount of downward movement of the screw rod 62 and the interval of the gap W between the lid 68 and the upper surface 54a of the sterilizer main body 54, and the amount of downward movement from the initial position of the screw rod 62 is detected. By making the amount of downward movement constant while the cover 6
It is possible to make the distance between the gap W and the upper surface 54a of the sterilizer main body 54 constant. In addition, the downward motion sensor 24

体５４の上面５４ａに押圧力が加わるからである。The operation of the vertical steam sterilizer 10 will be described. The operator fits the other end of the arm body 56 into the holding portion 60, turns the handle 66 to lower the lid 68 together with the screw rod 62, closes the opening of the sterilization container 52, and further attaches the lid 68 via the packing 70. And press against the upper surface 54a of the sterilizer main body 54. When the other end of the arm body 56 is fitted into the holding portion 60, a gap may be formed between the upper surface 56a of the other end of the arm body 56 and the inner upper surface 60a of the holding portion 60,
By turning the handle 66 and lowering the screw rod 62 so that the lid 68 is pressed against the upper surface 54a of the sterilizer main body 54, the arm body 56 is moved from its one end as a starting point to the other end, so that the holding section The first limit switch 22 is turned on by contacting the inner upper surface 60a of the first switch 60. The position of the screw rod 62 with respect to the arm body 56 in this state is defined as the above-described initial position. Because the arm body 56 is held down by the holding unit 60 and the other end does not move upward, the pressing force is actually applied from the lid 68 to the upper surface 54a of the sterilizer body 54 only after the screw rod 62 is further lowered.

As a result, the torque applied from the handle 66 to the screw rod 62 becomes a constant torque.
It is possible to mechanically prevent application of excessive pressure that may cause a failure to each component of the steam sterilizer 10, such as the packing 70 and the lid 68. As an example, as shown in FIG. 11, the torque limiter 36 is a disk portion 38 formed at the upper end of the screw rod 62 rotatably fitted in the handle 66.
And a hole 40 which is opened on the outer peripheral surface of the disk portion 38 and extends radially from the rotation axis of the screw rod 62, and a spring 4 is provided in the hole 40.
A sphere 44 constantly biased outward by 2 and stored;

When the user rotates the sphere 6, the sphere 44 urged by the spring 42 fits into the concave portion 46 at a position where the concave portion 46 of the handle 66 and the sphere 44 of the screw rod coincide with each other. As a result, the handle 66 and the disk portion 38 of the screw rod 62 are connected via the sphere 44, and when the handle 66 is turned, the screw rod 62 also rotates. However, the lid 68 contacts the upper surface 54a of the sterilizer main body 54,
As in the case where the downward movement of the screw rod 62 starts to be regulated,
When an external force is applied to block 2 to prevent rotation, and the external force increases, the force of the spherical body 44 pushed into the hole 40 from the concave portion 46 also gradually increases, and the pushing force urges the spherical body 44. When the biasing force of the spring 42 is exceeded, the sphere 44 moves into the hole 40, the engagement between the sphere 44 and the concave portion 46 is released, and the handle 66 idles with respect to the screw rod 62.
