The engaging portion 55 located on the opposite side with respect to the seal portion 56 is a portion that engages with the space closing member 33 and is a protrusion protruding from the end surface of the accommodating portion 53.
The engaging portion 55 has a male screw portion 62 threaded on the outer surface.
The axis of the engaging portion 55 coincides with the central axis of the main body cylinder portion 51 and also coincides with the axis of the female screw portion 39 of the engaging hole 35. The nominal diameter, pitch, and the like of the male screw portion 62 are the same as those of the female screw portion 39.

The exterior member 52 is a net rolled into a cylindrical shape as shown in FIG. That is, the exterior member 52 is a net made of metal or resin, and is molded in a three-dimensional plastic deformation so that the cross-sectional shape can be read as “C” so as to be read from FIGS. 5 and 6. is there. That is, the cross-sectional shape of the exterior member 52 is a sector shape exceeding 180 degrees, as can be seen from FIGS.
In other words, it has an arc shape having a missing portion 63 of about 60 degrees to 100 degrees. The width of the missing portion 63 is equal to or slightly larger than the vent openings 60 and 61. In other words, the article storage container 50 can set the test object 40 in the storage portion 53 by matching the missing portion 63 with the ventilation opening 60 or the ventilation opening 61.

The exterior member 52 is wound around the outer side of the accommodating part 53 of the main body cylinder part 51 so that it can read from FIG. 4, FIG. More specifically, the missing part 63 is expanded by being elastically deformed, and is attached to the outside of the accommodating part 53.
Since the exterior member 52 has elasticity, the outer surface of the housing portion 53 of the main body cylinder portion 51 is fastened by the inner surface thereof. Therefore, the exterior member 52 can maintain the attached posture.
However, when the exterior member 52 is grasped with fingers and turned, the exterior member 52 rotates relative to the main body cylinder portion 51.

  As shown in FIG. 1, the container holding device 31 is a combination of a rotating chuck 65 and a linear motion device 66.

The rotary chuck 65 includes a claw 67 for gripping a member and a motor 68 that rotates the claw 67 as shown by an arrow in FIG. In the present embodiment, the claw 67 is specifically a three-claw, and the claw 67 is opened and closed by a driving device (not shown).

The linear motion device 66 includes a linear drive device such as a cylinder 69 and a moving plate 71 attached to the tip of a rod 70 of the cylinder 69. The rotating chuck 65 is attached to the moving plate 71.
Therefore, when the rod 70 of the cylinder 69 is expanded and contracted, the moving plate 71 moves linearly and the rotary chuck 65 moves linearly.
In the present embodiment, the rotary chuck 65 is attached to the moving plate 71 in the same direction as the cylinder 69. Therefore, when the rod 70 of the cylinder 69 is extended, the rotary chuck 65 moves in a direction away from the test unit 30, and when the rod 70 is contracted, the rotary chuck 65 moves in a direction approaching the test unit 30.
The stroke length of the cylinder 69 on the inlet side of the container holding device 31 is substantially the same as or slightly longer than the length of the storage portion 53 of the article storage container 50.
The cylinder 69 of the container holding device 31 employs a dual cylinder and can perform a two-step slow motion.

  As other members, a stock member 72 is provided in the vicinity of the container holding device 31. The stock member 72 is a shelf for temporarily placing the article storage container 50.

  Next, the operation of the environment forming apparatus 1 of the present embodiment will be described along the usage procedure.

  First, prior to the use procedure, the state of the environment forming apparatus 1 before the article storage container 50 is inserted into the test unit 30 will be described.

As shown in FIG. 11A, the environment forming apparatus 1 is in a closed state in which the space closing member 33 enters and exits to close the through hole 25 and seals the test chamber 3.
Specifically, the restricting portion 43 (see FIG. 9) of the guide groove 41 of the space closing member 33 and the convex portions 23 and 24 of the large diameter portion 27 of the entrance / exit through-hole 25 are engaged, and the space closing member 33 is engaged. Closes the large-diameter portion 27 of the through-hole 25. That is, the space closing member 33 is restricted from moving in the insertion direction (lateral direction) by the restriction portion 43, and the test chamber 3 is sealed by the space closing member 33.
The door member 18 is in a closed state, and the inside of the test chamber 3 is in an airtight state.

Before the article storage container 50 or the like is inserted into the environment forming apparatus 1, the test target article 40 is put in and out of the article storage container 50 as shown in FIG. 6.
