PROBLEM TO BE SOLVED: To prevent a pipe connected to a pipe receiving part from being pushed into depth by external force. SOLUTION: This pipe receiving part comprises a receiving part 4 and a cap-shaped receiving member 13 slidably inserted into the receiving part 4, and a shock absorbing ring 18 elastically compressable in a pipe axial direction is provided between a step surface 4B formed at a depth end part of the receiving part 4 and a flange 17 formed at a depth end part of the cap-shaped receiving member 13. Pushing force applied to a pipe connected to the receiving member 13 is absorbed by elastic compression deformation of the shock absorbing ring 18, thereby the receiving member 13 is prevented from being pushed into depth.
