Abstract
A housing for a door lock device has an irregular outer perimeter with inside and outside curved corners. A sub housing for the door lock device has a similarly configured outer perimeter coupled to the perimeter of the housing. An O-ring is inserted in a groove in the housing perimeter for sealing the perimeters of the housing and sub-housing. The O-ring has a plurality of spaced gripping portions that have a width greater than the width of the groove before insertion therein for keeping the O-ring from springing out of the groove during assembly.
