That is, the upper coupling plate 410 and the lower coupling plate 420 of the present invention are firstly bonded by being connected by high energy density welding, and secondly by the adhesive 430 outside the welding portion 440. Are bonded.
- the upper coupling plate 410 and the lower coupling plate 420 are shown to be firmly bonded by the welding portion 440 and the adhesive 430. Since a plurality of fixing portions 415 are formed along the circumference of the upper adhesive surface, all portions corresponding to the fixing portions 415 are melted by high energy density welding, whereby the welding portions 440 are formed to form the upper coupling plate 410. ) And the lower coupling plate 420 are bonded to each other along the circumference.

- the shape of the lower coupling plate 520 is formed differently from the case of the fifth embodiment.
- both the upper coupling plate 510 and the lower coupling plate 520 are recessed, and when the two are bonded to each other, a wider sealed space 512 is formed therein.
- the fixing part 515 is alternately formed on the upper adhesive surface and the lower adhesive surface so that the upper coupling plate 510 and the lower coupling plate 520 are mutually symmetric, the upper coupling plate 510 and the lower coupling plate ( 520 is formed in the same shape with each other.
