ABSTRACT:
An electric motor is provided with a breather, which is made of elastic material such as rubber and provided with three triangular tongues protruding in the longitudinal direction of a tubular shaped breather body around about an aperture opening in the outside air. According to this invention, formation of waterdrops and membranous water is hindered in the aperture of the breather, and water penetration into the electric motor is prevented effectively.
