ROTARY ELECTRIC SHAVER

PROBLEM TO BE SOLVED: To allow a main blade to securely and smoothly cut long hair or vicious hair which has been cut by a hairline cutting blade. SOLUTION: A hairline cutting unit 5 is attached at the upper side, which is the upper direction of the rotational direction of an inner blade 2, of a body case 1 as well as is positioned at a height for 'combination cutting' in which a hairline cutting blade 41 attached above the hairline cutting unit 5 approaches the side of the main blade. Hair guiding holes 32 in which a group of small holes are arranged in a mesh form are formed at an inner blade contact-sliding range A of an outer blade 3, multiple long holes 33 are formed in parallel circumferentially at the right and left parts of the hair guiding holes 32 where is the upper direction of the rotational direction of the inner blade, and a part of the end of the long holes 33 where is the lower side of the rotational direction of the inner blade is overlapped on the end of the inner blade contact- sliding range A where is the upper side of the rotational direction of the inner blade. Long hair or vicious hair which has been roughly cut by the hairline cutting blade 41 is treated and guided into the long holes 33 of the outer blade 3 and cut by the inner blade 2, then is guided into the hair guiding holes 32 in a mesh form and finally cut by the inner blade 2.
