Claims

[Scope of claim for utility model registration] Inserting and fitting the protruding part of the connector provided at the tip of the pipe into the fitting hole of the mating part, and applying a sealant placed in advance to the base of the protruding part to receive the seal of the fitting hole. In a pipe connection structure that is pressed against a seat for sealing, a protruding stepped portion for an insertion guide is formed at the base of the protruding portion of the connector, leaving a tip portion, and a fitting hole of the mating component is formed to receive the protruding stepped portion. A receiving guide portion for the connector is formed at a corresponding position, and a seal receiving seat is formed at a position having a depth greater than the length of the tip end of the connector from the opening edge of the fitting hole. Connection structure.
