Blade of hair removal device and hair removal device including blade of hair removal device

A blade part for a hair removal device, the blade part comprising:

• a fixed blade;
• and
• a movable blade that reciprocatingly slides with respect to the fixed blade, the blade part being adapted to cut hair with the fixed blade and the movable blade, wherein
• the fixed blade has a plurality of fixed blade bars arranged side by side in a reciprocating sliding direction of the movable blade with respect to the fixed blade, and a plurality of fixed blade grooves arranged side by side in the reciprocating sliding direction,
• the movable blade has a plurality of movable blade bars arranged side by side in the reciprocating sliding direction, and a plurality of movable blade grooves arranged side by side in the reciprocating sliding direction,
• each of the fixed blade bars includes a fixed-side hair cutting region capable of cutting hair,
• each of the movable blade bars includes a movable-side hair cutting region capable of cutting hair,
• when a center of one of the movable blade bars in the reciprocating sliding direction is made coincident with a center of one of the fixed blade grooves in the reciprocating sliding direction in viewing along an overlapping direction of the fixed blade and the movable blade, edges on both sides of the movable-side hair cutting region in the reciprocating sliding direction are overlapped with the fixed-side hair cutting region,
• when a center of one of the fixed blade bars in the reciprocating sliding direction is made coincident with a center of one of the movable blade grooves in the reciprocating sliding direction in viewing along an overlapping direction of the fixed blade and the movable blade, edges on both sides of the fixed-side hair cutting region in the reciprocating sliding direction are overlapped with the movable-side hair cutting region,
• (1) widths of at least two fixed blade bars of the plurality of fixed blade bars in the reciprocating sliding direction are the same, except for the ones at opposite ends of the fixed blade, and (2) widths of the plurality of fixed blade grooves are the same in the reciprocating sliding direction,
• (1) widths of the plurality of movable blade bars are the same in the reciprocating sliding direction, and (2) widths of the plurality of movable blade grooves the are the same in the reciprocating sliding direction, and
• the widths of the movable blade grooves are different from the widths of the fixed blade grooves.
