Outer cutter assembly for an electric shaver

An outer cutter assembly for an electric shaver which comprises:

• an outer shearing foil formed with a plurality of hair entrance peripheral perforations arranged along the periphery thereof to be in hair shearing relation with an inner blade sliding against the inner surface of the outer shearing foil;
• a base frame on which the outer shearing foil is mounted with its peripheral edge supported thereby;
• a comb forming plastic member provided between the peripheral edge of the outer shearing foil and the upper end of the base frame to have its lower portion connected to the base frame, said comb forming member being provided at its upper portion with a comb having teeth defining between the adjacent ones thereof slits each of which is in open communication with one of the peripheral perforations as well as located inside of the outer shearing foil, the teeth being in alignment with each of a plurality of webs separating adjacent ones of the peripheral perforations;
• adjoining means for bringing each of the teeth in intimate contacting relation with each corresponding one of the webs to thereby prevent the presence of any gap therebetween;
• said base frame being formed at its upper end with a projection which defines said adjoining means projecting into said comb forming member to separate the comb from the lower portion of the comb forming member in such a way that the upper portion undergoes shrinkage upon its solidification substantially independently of the shrinkage in the lower portion of the comb forming member, whereby the comb is subjected to a lesser amount of shrinkage so as to assure an intimate contacting relation between the teeth of the comb and the webs of the outer shearing foil.
