To provide a lever type connector capable of preventing deterioration of a seal property due to shrinkage during molding.

An annular seal ring 14 is fit on an outer circumferential face of a female side connector housing 10, and a lever 20 provided with a cam groove 24 is attached to an outer circumferential face of a hood part 12 covering its periphery. A male side connector housing 40 is provided with a cylindrical fitting part 41 capable of fitting in the female side connector housing 10 and a cam pin 43 is protrudedly provided on its outer circumferential face. In a normally fit state, an interior of the cylindrical fitting part 41 is sealed from an exterior by adherence of the seal ring 14 to a seal face S of an inner circumference of the cylindrical fitting part 41. Since the cam pin 43 is arranged deviated in a fitting direction to the seal face S, even when sinking occurs on the back side of the cam pin 43 during molding, deterioration of a sealing property due to this can be prevented.
