A waterproof connector is a connectable to a device-side connector (80) and has a housing (30) with a fitting (34) that can fit into an outer tube (82) of the device-side connector (80). A connector seal ring (36) is fit on an outer peripheral surface of the fitting (34) and is held resiliently in close contact with the outer tube (82) and the fitting (34). Individual terminal accommodating portions (37) are provided in the housing (30) and can fit into device-side cavities (84) provided in the device-side connector (80). Individual seal rings (38) are fitted on outer peripheral surfaces of the individual terminal accommodating portions (37) and are held resiliently in close contact with inner peripheral surfaces of the device-side cavities (84) and the individual terminal accommodating portions (37). The connector seal rings (36) and the individual seal rings are displaced in a front-rear direction.
