A razor cartridge may include a frame including a receiving space formed therein. The razor cartridge may also include a blade housing receiving at least one shaving blade in a longitudinal direction and mounted on the frame in a mounting direction to enable at least one of movement and rotation with respect to the frame. The razor cartridge may further include a tension supporting unit supporting the blade housing to provide a restorative force to restore the blade housing to a rest position. The frame may further include a first recess formed at a top of a frame side wall and a second recess formed at the frame side wall and spaced apart from the first recess in the mounting direction. The blade housing may be mounted on the frame by inserting a mounting protrusion into the second recess through the first recess.
