1. A quick connector comprising:
a connector body into which a piped body having an annular boss can be inserted; and
a retainer provided movably relative to the connector body from an initial position to a confirmation position by a push-in operation in a direction crossing an axial direction of the connector body, and the retainer locking in the axial direction to the annular boss at the confirmation position,
the retainer including:
a base;
paired locking legs provided at both ends of the base,
allowing passing of the annular boss at the initial position, and locking in the axial direction to the annular boss at the confirmation position; and
paired detecting legs provided at both ends of the base and on an inner side in the axial direction from the paired locking legs, bending to the inner side in the axial direction by contact with the annular boss at the initial position, and allowing the retainer to move to the confirmation position in a state where the paired detecting legs bend,
each of the paired detecting legs including:
a detection portion provided on the end side of the detecting leg to protrude inward in a diametric direction, and contacting with the annular boss at the initial position; and
a push-in inhibition portion provided to the detecting leg on the side of the base from the detection portion, locked in a push-in direction to the connector body in a state where the detecting leg does not bend to the inner side in the axial direction at the initial position, and put in such a state as being not locked in the push-in direction to the connector body in a state where the detecting leg bends to the inner side in the axial direction.
2. The quick connector as set forth in claim 1, wherein
the bending of the detecting leg to the inner side in the axial direction is canceled at the confirmation position,
the detection portion is locked in the pull-out direction to the connector body at the confirmation position, and
the push-in inhibition portion is put in such a state as being not locked in the pull-out direction to the connector body at the confirmation position.
3. The quick connector as set forth in claim 1, wherein
the connector body includes a push-in locked portion locked to the push-in inhibition portion at the initial position, and
at least one of the push-in inhibition portion and the push-in locked portion has a push-in inhibition inclined face inhibiting the moving of the retainer in the push-in direction in such a manner that the push-in inhibition portion and the push-in locked portion are pressed onto each other and the detecting leg then bends to the insertion side in the axial direction, when the push-in operation of the retainer is carried out in a state where the detect leg does not bend to the inner side in the axial direction.
4. The quick connector as set forth in claim 3, wherein
at least one of the push-in inhibition portion and the push-in locked portion has a return inclined face guiding the push-in inhibition portion so as to cancel the bending of the detecting leg to the inner side in the axial direction, when the detecting leg comes into contact with the annular boss at the initial position to bend to the inner side in the axial direction and the contacting of the detecting leg onto the annular boss is then canceled.
5. The quick connector as set forth in claim 4, wherein
the push-in inhibition inclined face is formed in the push-in locked portion,
a normal vector of the push-in inhibition inclined face has a component on the insertion side in the axial direction and a component in the pull-out direction,
the return inclined face is formed on the inner side in the axial direction from the push-in inhibition inclined face, in some of the push-in locked portion, and
a normal vector of the return inclined face has a component on the inner side in the axial direction and a component in the pull-out direction.
6. The quick connector as set forth in claim 1, wherein
the push-in inhibition portion is provided to protrude outward in the diametric direction of the detecting leg.
