外筒固定ネジ４４は、図８に示すように、ネジ軸部４７、及びネジ頭部４８を有する。ネジ頭部４８は、ネジ軸部４７の一方のネジ軸端４７Ａに固定される。
外筒固定ネジ４４において、ネジ軸部４７は、図８に示すように、他方のネジ軸端４７Ｂから外筒固定長穴部４２に挿入して、内筒固定部４１（内筒固定板４６）の外筒固定ネジ穴部４３に螺着される。ネジ軸部４７は、外筒体３を移動自在として外筒固定長穴部４２に挿通される。外筒固定ネジ４４において、ネジ頭部４８は、外筒体３の外周面３Ｎに当接自在に配置される。 As shown in FIG. 8, the outer cylinder fixing screw 44 has a screw shaft portion 47 and a screw head portion 48. The screw head 48 is fixed to one screw shaft end 47 </ b> A of the screw shaft portion 47.
In the outer cylinder fixing screw 44, as shown in FIG. 8, the screw shaft portion 47 is inserted into the outer cylinder fixing elongated hole portion 42 from the other screw shaft end 47B, and the inner cylinder fixing portion 41 (inner cylinder fixing plate 46). ) And the outer cylinder fixing screw hole 43. The screw shaft portion 47 is inserted into the outer tube fixing long hole portion 42 so that the outer tube body 3 is movable. In the outer cylinder fixing screw 44, the screw head 48 is disposed so as to be in contact with the outer peripheral surface 3 </ b> N of the outer cylinder 3.

外筒固定ネジ４４は、ネジ軸部４７の一方の回転に伴って、ネジ頭部４８を外筒体３の外周面３Ｎに当接し、及び外筒体３の内周面３Ｍを内筒固定板４６（内筒固定部４１）に押付ける。
このとき、外筒体３、及び内筒固定板４６（内筒固定部４１）は、外筒固定ネジ４４の締付力を受けて弾性変形する。また、ネジ軸部４７は、外筒固定ネジ穴部４３に螺入されて、内筒体２の外周面３Ｎに接触することなく、ネジ空間δｅ内に突出される。
これにより、外筒体３の内周面３Ｍ及び内筒固定板４６（内筒固定部４１）は、締付力によって密接に接触して、外筒体３を内筒体２（内筒固定部４１）に固定して、内筒体２に対して外筒体３を移動不能にする。
外筒固定ネジ４４は、外筒体３を内筒体２に固定した後に、ネジ軸部４７の他方の回転に伴って、外筒体３の内周面３Ｍを内筒固定板４６（内筒固定部４１）から離間して、外筒体３の内周面３Ｍ及び内筒固定板４６（内筒固定部４１）の間に締付隙間δｄ（締付け空間）を空ける。
このとき、外筒体３及び内筒固定板４６は、外筒固定ネジ４４の締付力から開放され、外筒体３の内周面３Ｍ及び内筒固定板４６の間に締付隙間δｄ（締付空間）を形成する。
これにより、外筒体３は、内筒体２（内筒固定部４１）に対する固定が解錠されて、内筒体２に対して移動自在にされる。
このように、外筒固定手段５は、外筒固定ネジ４４（ネジ軸部４７）を回転（一方の回転、他方の回転）することで、外筒体３を内筒体２に移動不能に固定し、及び内筒体２に対する外筒体３の固定を解除して、外筒体３を移動自在にする。 The outer cylinder fixing screw 44 abuts the screw head 48 against the outer peripheral surface 3N of the outer cylindrical body 3 and fixes the inner peripheral surface 3M of the outer cylindrical body 3 to the inner cylinder with one rotation of the screw shaft portion 47. Press against the plate 46 (inner cylinder fixing portion 41).
At this time, the outer cylinder 3 and the inner cylinder fixing plate 46 (inner cylinder fixing portion 41) are elastically deformed by receiving the tightening force of the outer cylinder fixing screw 44. Further, the screw shaft portion 47 is screwed into the outer cylinder fixing screw hole 43 and protrudes into the screw space δe without contacting the outer peripheral surface 3N of the inner cylinder body 2.
Thereby, the inner peripheral surface 3M of the outer cylinder 3 and the inner cylinder fixing plate 46 (inner cylinder fixing portion 41) are in close contact with each other by the tightening force, and the outer cylinder 3 is fixed to the inner cylinder 2 (inner cylinder fixing). The outer cylinder 3 is made immovable with respect to the inner cylinder 2 by being fixed to the portion 41).
After the outer cylinder 3 is fixed to the inner cylinder 2, the outer cylinder fixing screw 44 moves the inner peripheral surface 3 </ b> M of the outer cylinder 3 to the inner cylinder fixing plate 46 (inner A clamping gap δd (tightening space) is opened between the inner peripheral surface 3M of the outer cylindrical body 3 and the inner cylinder fixing plate 46 (inner cylinder fixing part 41) apart from the cylinder fixing part 41).
At this time, the outer cylinder 3 and the inner cylinder fixing plate 46 are released from the tightening force of the outer cylinder fixing screw 44, and a tightening gap δd between the inner peripheral surface 3M of the outer cylinder 3 and the inner cylinder fixing plate 46 is obtained. (Tightening space) is formed.
As a result, the outer cylinder 3 is unlocked from being fixed to the inner cylinder 2 (inner cylinder fixing portion 41), and is movable relative to the inner cylinder 2.
Thus, the outer cylinder fixing means 5 makes the outer cylinder 3 unmovable to the inner cylinder 2 by rotating the outer cylinder fixing screw 44 (screw shaft portion 47) (one rotation, the other rotation). The outer cylinder body 3 is fixed and the outer cylinder body 3 is released from being fixed to the inner cylinder body 2 to make the outer cylinder body 3 movable.

脱気筒Ｘにおいて、外筒体３は、図７に示すように、外筒開口端３Ｂから内筒体２に外嵌される。
このとき、外筒体３に設けた各ガイド部３２を、内筒体２に設けた各ガイド溝部３１に摺動自在に挿入すると、各外筒固定長穴部４２のうち、１の外筒固定長穴部４２は、図９に示すように、内筒固定部４１（内筒固定板４６）に対峙して配置される。

また、外筒固定手段５において、外筒固定ネジ４４及び外筒固定長穴部４２は、外筒体３の移動を第１位置Ｐ１及び第２位置Ｐ２の間に規制する、外筒移動規制手段（又は外筒固定規制手段）となる。
外筒固定手段５は、第１位置Ｐ１及び第２位置Ｐ２を含む、第１位置Ｐ１及び第２位置Ｐ２間の任意の位置において、外筒固定ネジ４４を一方に回転し、又は他方に回転することで、外筒体３を内筒体２に移動不能に固定し、及び外筒体３の固定を解除して外筒体３を移動自在にする。 In the decylinder X, the outer cylinder 3 is moved with respect to the inner cylinder 2 while being guided by the guide groove portions 31 and the guide portions 32 (outer cylinder guide means 4). At this time, each guide part 32 slides in each guide groove part 31. Further, the outer cylinder 3 is moved while being guided by the outer cylinder fixing long hole portion 42 and the outer cylinder fixing screw 44.
When the outer cylinder 3 is moved toward the plate surface 15X of the support substrate portion 15 (the plate surface of the base plate 1), the screw shaft portion 47 of the outer cylinder fixing screw 44 becomes as shown in FIG. 3, the length of one long hole end 42 </ b> A [upper side (inner cylinder opening end 2 </ b> B side) of the outer cylinder fixing elongated hole portion 42 (the outer cylinder fixing elongated hole portion 42 facing the inner cylinder fixing plate 46).

At the first position P1, as shown in FIGS. 1 and 7, the outer cylinder 3 has a cylinder end gap δa (cylinder end) between the outer cylinder closed end 3A and the other inner cylinder opening end 2B of the inner cylinder 2. And an exhaust gap δc (exhaust space) is disposed between the outer cylinder opening end 3B and the plate surface 15X of the support substrate portion 15.
When the outer cylinder 3 is moved in a direction away from the plate surface 15X of the support substrate 15 (the plate surface of the base plate 1), the screw shaft portion 47 of the outer tube fixing screw 44 is moved as shown in FIG. Along with the movement of the cylindrical body 3, it comes into contact with the other long hole end 42 </ b> B [lower hole (base plate 1 side) long hole end] of the outer cylinder fixed long hole portion 42.
As a result, as shown in FIG. 31, the outer cylinder 3 is restricted from moving toward the other inner cylinder opening end 2B side of the inner cylinder 2 in the cylinder centerline direction IC of the inner cylinder 2. The opening end 3B is disposed (positioned) at the second position P2.

32 and 33, the humid air generated from the ground concrete A (concrete slab) flows into the inner cylinder 2 through the vent hole C and the exhaust hole 11 of the base plate 1, and the other inner cylinder of the inner cylinder 2. From the opening end 2B to the cylinder end gap δa (between the outer cylinder closed end 3A and the other inner cylinder opening end 2B) and the cylinder circumferential gap δb (the inner peripheral surface 3M of the outer cylindrical body 3 and the outer peripheral surface 2N of the inner cylindrical body 2) Flows in the order). The humid air flowing through the cylinder circumferential gap δb is exhausted (released) into the atmosphere from each outer cylinder fixing slot 42 and the exhaust gap δc [between the finishing layer D and the outer cylinder opening end 3B].
