PURPOSE:To reliably seal a compressor, and easily mount and remove a sealing member, by providing the sealing member with an invertible portion, by inverting the invertible portion to bring the invertible portion into pressure contact with an inner wall of a tube. CONSTITUTION:A sealing portion 22b for sealing an end opening of a tube 21 is formed at its central portion with an invertible portion 22c having an arcuate shape in section. In mounting a sealing member 22 to the tube 21, the invertible portion 22c is pressed to be inverted in the same direction as an inserting direction of the sealing member 22, thereby bringing the sealing portion 22b into pressure contact with an inner wall of the tube 21. Thus, the sealing may be effected at the inner wall of the tube 21 to reliably seal a compressor. Further, the sealing member 22 may be easily removed by prying same with a cap opener or the like.
