摘要

PROBLEM TO BE SOLVED: To provide a pipe connection structure whereby a tip of a pipe can be easily and quickly connected and fixed to a mating member.SOLUTION: A carriage body frame (11) of a baby carriage comprises: a pipe-like frame member (15) which extends in a width direction of the baby carriage and has an inwardly oriented flange part (15f) at a tip thereof, the inner peripheral edge of the inwardly oriented flange part forming a tip opening (15h); a mating member (13) having an open hole (13h) which extends in the width direction of the baby carriage; a connector (41) which connects the tip of the frame member with the mating member by a deformation part (42e) of the connector (41), which is inserted into the tip opening of the frame member through the open hole and which is so deformed as to expand a diameter of the deformation part (42e).
