PROBLEM TO BE SOLVED: To prevent floating of a detection member while avoiding the up-sizing and complication of the housing.SOLUTION: A detection member 40 is assembled movably between an initial position and a detection position for the housing 10, subjected to flexural deformation in the process from the initial position to the detection position, and held in such a state as returning to the initial position is regulated for a lock arm 21 at the detection position. A retainer 80 is attached to the housing 10. The retainer 80 is provided with a regulation part 86 that is arranged, when attached normally to the housing 10, at a position corresponding to the relief portion 46 of the detection member 40, in the process where the detection member 40 moves from the initial position to the detection position, and allowing deflection of the detection member 40, and arranged at a position deviated from the relief portion 46 when the detection member 40 reaches the detection position, and regulating deflection of the detection member 40. |
