PROBLEM TO BE SOLVED: To provide a locking structure of a terminal fitting and a connector housing which can suppress the damage of an elastic locking arm portion.SOLUTION: A locking structure 1 of a terminal fitting and a connector housing locks the terminal fitting 10 in a terminal storage chamber 30 by a locking protrusion 15 of the terminal fitting 10 and an elastic locking arm portion 50 of the connector housing 20. The elastic locking arm portion 50 extends a part of a tip end to a position at least partially covering the locking protrusion 15 at a locking position, and has a tip end extending portion 51 made by forming a locking protrusion corresponding shaped surface 51a in a shape fitting with the outer shape of the locking protrusion 15 so as to decrease a clearance between the tip end extending portion 51 and the locking protrusion 15 at the locking position, while the elastic locking arm portion 50 is elastically neutral. If separation force is applied on the terminal fitting 10, while the terminal fitting 10 is locked to the elastic locking arm portion 50, the separation force is applied at a lower side position of a slip-off preventive surface 50a and near a base end portion 51b of the tip end extending portion 51. |
