Bending face 7w on.It is formed with circular hole 17 in the central authorities of sliding panel 7.Sliding panel 7 under assembled state (with reference to Fig. 1) is set to
Loosen the state on the upper pearl portion 3c of barrier film 3, and in the state of the underside shape along carrier 6, setting
For being installed in carrier 6 and barrier film 3 state in-between.Thus, under regular assembled state, the upper support of sliding panel 7
Portion 1 and carrier 6 are installed with the concentric with regard to axle center p.
In addition, as in Fig. 1 and Fig. 2 (b) so that, shown in dummy line, return portion k is also configured to be arranged on fore-and-aft direction
On a side of any one thinner thickness in the position of position and left and right directions, i.e. be arranged in the downside of flat part 6a
On gently sloping surface portion 7y.Or, also return portion k can be arranged on thickness change section, can also be arranged on described flat part 6a,
More than abundant part 6b, thickness change section one of are worked as.
As reference, it is arranged on using the existing sliding panel 7 between the carrier 6 of anisotropic structure and barrier film 3, i.e.
The sliding panel 7 of return portion k not figure 5 illustrates with oblique view.This sliding panel 7 includes having and is equivalent under flat part 6a
The gently sloping surface portion 7y of the shape of surface configuration, the facial 7w of bending of the shape with the underside shape being equivalent to abundant part 6b
Change face 7h with the shape with the underside shape being equivalent to thickness change section.
Here, the defect being interposed in the situation between carrier 6 and barrier film 3 to the existing sliding panel shown in Fig. 5 is entered
Row explanation., when beyong contemplation disappointing or when entering during garage, meeting is as shown in fig. 6, become barrier film 3 for air spring a
In the state missed of air, i.e. gas leakage state.Under gas leakage state, due to barrier film 3 sagging in the upper purgation with receiving portion 6
Between formed gap space sk, for this gap space sk, sliding panel 7 become as shown in Figure 6 except still be clamped inner circumferential
Side part, the sagging state of other parts.
Peripheral part sliding panel sagging on a large scale 7 is in the state almost not having upper and lower chucking power, thus vibrations etc. lead to
It is easier to rotate around the p of axle center, thus there is the rough sledding such as position skew.If position shifts, for example, delay
When inclined plane part 7y is located at the lower section of abundant part 6b, inflation thereafter can make the gently sloping surface portion 7y being clipped between barrier film 3 and carrier 6
Bear undue power, thus occurring sliding panel 7 to produce the faults such as cracking or crackle.
In order to prevent the generation of described rough sledding and fault, have and paste and slide in the carrier of upper supporting part and barrier film top
The method of dynamic plate.But, binding agent is coated uniformly on meeting expense and time known to the step on larger area, without
Also it is unfavorable for improve production efficiency while Ji.In addition, existing in sliding panel because carrier is different with the material of sliding panel
On crack, sliding panel that this splits leads to the risk of diaphragm injury, therefore also further room for improvement.
Here, by carefully studying, air spring a is the knot being provided with return portion k on sliding panel 7 in the present invention
Structure.As shown in Figure 4, even at gas leakage state, by the return portion k of carrier 6 upside, sliding panel 7 can avoid sagging, can
Maintain the state of the lower surface along carrier 6.Although return portion k is formed at the facial 7w of bending in the diagram, as dummy line institute
Show, can also be provided on gently sloping surface portion 7y.
The air spring a that return portion k is formed on the facial 7w of bending of corresponding abundant part 6b have the advantage that due to
It is the thick part of thickness in carrier 6, the bending face 7w that therefore easily will be provided with return portion k is pressed in abundant part 6b,
It is easy to grasp.
The air spring a that return portion k is formed on the gently sloping surface portion 7y of corresponding flat part 6a have the advantage that if
Carrier 6 and sliding panel 7 rotate against around the p of axle center, then in rotary moving so that return portion k and thickness change section abut, because
This can pin down to stop and be offset by the position that rotation causes.
