Door lock device pair
A door lock device pair includes right and left door lock devices; each of the door lock devices including: a housing; a coupler wall projecting from the housing; a flat portion formed on the housing; and a waterproof seal fixed to the flat portion and being wrapped around the coupler wall, the waterproof seal including: inner and outer peripheral surfaces; and an inclined surface that forms an acute angle with respect to the inner peripheral surface and an obtuse angle at another end of the inclined surface, the inner peripheral surface being in contact with the outer peripheral wall and being in contact with the inclined surface, and the waterproof seals in the door lock devices having the same shape, and the waterproof seals being wrapped around the respective outer peripheral walls in the same direction.
1. A door lock device pair applied to a vehicle, the door lock device pair comprising:
a right door lock device; and
a left door lock device, wherein
each of the right door lock device and the left door lock device includes:
a housing;
a coupler wall formed in a tubular shape and projecting from the housing;
a flat portion formed in a periphery of the coupler wall and on the housing; and
a waterproof seal fixed to the flat portion and being wrapped around and cover an outer peripheral wall of the coupler wall,
wherein the waterproof seal includes:
an inner peripheral surface;
an outer peripheral surface; and
an inclined surface that forms an acute angle with respect to the inner peripheral surface at one end of the inclined surface and forms an obtuse angle with respect to the outer peripheral surface at another end of the inclined surface,
wherein the inner peripheral surface is brought into contact with the outer peripheral wall of the coupler wall in an extending manner around the outer peripheral wall of the coupler wall and further brought into contact with the inclined surface,
wherein the waterproof seals in the right door lock device and the left door lock device are wrapped around the respective outer peripheral walls of the coupler walls in respective directions identical to each other,
wherein, when the right door lock device is placed in a right door of the vehicle and when the left door lock device is placed in a left door of the vehicle, the waterproof seal of the right door lock device and the waterproof seal of the left door lock device are not mirror-image symmetrical to each other,
wherein the waterproof seal of the right door lock device is not reversely arranged on the outer peripheral wall of the coupler wall in comparison with the waterproof seal of the left door lock device so that a shape of the waterproof seal of the right door lock device and a shape of the waterproof seal of the left door lock device appear identical to each other, and
wherein each flat portion is formed in a shape extending along a fixing surface of the respective waterproof seal.
2. The door lock device pair according to claim 1 , wherein
the coupler wall includes
a cylinder part having a constant height from the flat portion, and
a projecting portion further projecting from the cylinder part and being formed in a range of 180 degrees or less with respect to an entire circumference of the coupler wall.
3. The door lock device pair according to claim 1 , wherein
each of right door lock device and the left door lock device includes a plurality of housings, and
the flat portion is formed in an extending manner over each of the housings.
4. The door lock device pair according to claim 1 , wherein the acute angle formed at the one end of the waterproof seal is in the range of 40 degrees to 50 degrees.
5. The door lock device pair according to claim 1 , wherein a corner part formed on an inner peripheral side of the another end of the waterproof seal coincides with the obtuse angle part formed at the one end of the waterproof seal.
6. The door lock device pair according to claim 1 , wherein
the side view of the right door lock device shows the flat portion of the right door lock device with an area surrounded by the coupler wall of the right door lock device visible, and
the side view of the left door lock device shows the flat portion of the left door lock device with an area surrounded by the coupler wall of the left door lock device visible.
