Claim Text:
1. A lever-type connector, comprising: a housing connectable to a mating housing and including a front end that is connectable to the mating housing and a rear end opposite the front end, the housing further having a terminal accommodating portion extending substantially from the front end to the rear end and a substantially tubular fitting wall outward of the terminal accommodating portion, shafts projecting on opposite side surfaces and a contact-stop wall projecting from the opposite side surfaces between the terminal accommodating portion and the fitting wall and a forwardly open connection space being defined between the terminal accommodating portion and the fitting wall at positions forward of the contact stop wall, the contact stop wall being capable of stopping the mating housing; a seal ring mounted on the housing adjacent the contact-stop wall and being sandwiched in a fluid-tight manner between the two housings when the two housings are connected; and a lever including a coupling and arm plates projecting from opposite ends of the coupling to define a U-shape, the lever being mounted from an outer side to straddle the housing and being rotatable about the shafts while being engaged with the mating housing to generate a force multiplying action for connecting the two housings; wherein the contact-stop wall is arranged at a position facing the arm plates from inner sides of the arm plates and a confirmation window is provided in at least one of the arm plates through which the seal ring is visible, and wherein the fitting wall of the housing includes outward deformation preventing walls at outer sides of the arm plates to prevent excessive outward deformation of the arm plates when rotating the lever, at least one of the outer deformation preventing walls including an escaping portion defining an opening in at least one of the deformation preventing walls and extending from the contact-stop wall to a location forward of the seal ring and communicating with the confirmation window to make the seal ring visible.
