Claim 18:
19. The internal heat exchanger according to claim 17, wherein
a positional relationship between the distal end of the inner pipe, the inner pipe side sealing member, the distal end of the outer pipe, and the outer pipe side sealing member, and the inner pipe insertion portion, the outer pipe insertion portion, and the contact portion of the connector define a structure,
at inserting the inner pipe and the outer pipe into the connector,
first, the distal end of the inner pipe comes into contact with the inner pipe insertion portion, next, the distal end of the outer pipe comes into contact with the outer pipe insertion portion, after that, the inner pipe side sealing member comes into contact with the inner pipe insertion portion, after that, the outer pipe side sealing member comes into contact with the outer pipe insertion portion, and finally the contact portion comes into contact with the connector.
