DOOR LOCKING DEVICE PAIR

It is an object of the present invention to provide a door lock device pair having good workability when a waterproof seal is fixed to a housing, and having a high yield of the waterproof seal. A door lock device pair 10 includes a right door lock device 10R and a left door lock device 10L. Each of the right door lock device 10R and the left door lock device 10L has a coupler wall 18a projecting from the housing, and a coupler seal 22 fixed to a flat portions 36R (in the case of the right door lock device 10R) or a flat portion 36L (in the case of the left door lock device 10L) to cover an outer peripheral wall 18ao of the coupler wall 18a. The coupler seal 22 has an inner peripheral surface 22a, an outer peripheral surface 22b, and an inclined surface 22e. The inclined surface 22e of the coupler seal 22 forms an acute angle part 22f with an angle of 45 degrees with the inner peripheral surface 22a, and forms an obtuse angle part 22g with the outer peripheral surface 22b. The inner peripheral surface 22a is brought into contact with the outer peripheral wall 18ao in an extending manner around the outer peripheral wall 18ao, and further brought into contact with the inclined surface 22e. The coupler seals 22 in the right door lock device 10R and the left door lock device 10L have shapes identical to each other.
