Abstract:
A flexible pipe connector comprising:a first cylindrical member;a second cylindrical member configured to be inserted into the first cylindrical member, the second cylindrical member being supported by the first cylindrical member so as to be slidably movable relative to the first cylindrical member in a cylindrical axis direction;an annular restricting groove defined in an inner peripheral face of the first cylindrical member;an annular attaching groove defined in an outer peripheral face of the second cylindrical member;a retaining member fitted to the attaching groove for coming into contact with an end face of the annular restricting groove in the cylinder axis direction so as to restrict a relative movement between the first and second cylindrical members in the cylinder axis direction; anda radial-expansion restricting portion defined in the first cylindrical member, the radial-expansion restricting portion restricting a radial-expansion of the retaining member via contact with the retaining member in a radial direction so as to prevent a withdrawing movement of the retaining member from the attaching groove when the retaining member comes into contact with an end face of the restricting groove due to the relative slidable movement,wherein said radial-expansion restricting portion includes a radial-expansion restricting face of a restricting member engaged and retained at one end of an inner peripheral face of the restricting groove in such a manner as to approach the outer peripheral face of the retaining member contacting against the end face of the restricting groove.
