Razor head

A razor head, comprising:

• a frame;
• and
• elongated blades arranged on an inner side of the frame, wherein the frame includes:
• two opposing long side walls;
• two opposing short side walls;
• and first, second, and third bridge walls each extending between the two opposing long side walls in an interior of the frame,
• the first bridge wall extends between a middle of the two opposing long side walls in a longitudinal direction of the frame,
• the second bridge wall and the third bridge wall extend on opposite sides of the first bridge wall, respectively,
• the second bridge wall and the third bridge wall are symmetrical with respect to the first bridge wall,
• a length of the first bridge wall in the longitudinal direction is greater than lengths of the second and third bridge walls in the longitudinal direction,
• the second bridge wall has a first narrow portion recessed from a side surface of the second bridge wall facing the first bridge wall and the third bridge wall has a second narrow portion recessed from a side surface of the third bridge wall facing the first bridge wall,
• the first and second narrow portions between the two opposing long side walls are portions where the second and third bridge walls are connected to one of the two opposing long side walls, the second and third bridge walls each including include protrusions projections arranged in an arrangement direction of the blades,
• a length of each of the protrusions in the longitudinal direction is equal to the lengths of each of the second and third bridge walls in the longitudinal direction,
• each of the blades is held between adjacent protrusions of the second and third bridge walls,
• each of the protrusions includes:
• a first flat surface that is in contact with one of the blades located on one side of the protrusion in the arrangement direction;
• a second flat surface that is in contact with another of the blades located on the other side of the protrusion in the arrangement direction;
• and
• a third flat surface and a fourth flat surface that are inclined with respect to the first flat surface and the second flat surface,
• the first flat surface is parallel to the second flat surface,
• the third flat surface is parallel to the fourth flat surface,
• in each of the second and third bridge walls,
• the first flat surface and the second flat surface are offset from each other in a longitudinal direction of the blades so as not to overlap each other as viewed in the arrangement direction, and
• the first flat surfaces are located on the same position as viewed in the arrangement direction and the second flat surfaces are located on the same position as viewed in the arrangement direction.
