It is aimed to maximally suppress the inclination of a terminal fitting in a terminal accommodating chamber. A connector includes a terminal fitting having a wire connecting portion connected to an end of a wire, a housing having a terminal accommodating chamber into which the terminal fitting is to be inserted from behind, and a sleeve fitted on a rear side of the terminal fitting while surrounding the wire connecting portion of the terminal fitting and functioning to retain the terminal fitting by locking both front and rear end parts to the terminal fitting and a wall surface of the terminal accommodating chamber. An inclination regulating portion configured to regulate such inclination of the terminal fitting relative to the sleeve as to incline axial lines of the terminal fitting and the sleeve relative to each other is provided near a fitting part of the terminal fitting and the sleeve.
