Abstract
The connection structure of alternator mount stays with a drive frame and a rear frame is strengthened so that increased vibration of the alternator's rotor and a stator is prevented and, accordingly, generation of magnetic noise is suppressed. The alternator is provided with generally triangular engine-mounting stays which are secured to an engine. A plurality of stay-reinforcement ribs are integrally formed with sides of the engine-mounting stays of the alternator and with the bottom of outer peripheries of the alternator, thereby increasing the rigidity of the stays. Consequently, vibrations from the engine are not amplified by the engine-mounting stays or transmitted to the drive frame or to the rear frame, thereby suppressing an increase in vibration of the rotor and the stator. Deformation of the drive frame and the rear frame due to the vibration transmitted from the engine is also prevented. As a result, an increase in distortion of the magnetic field is prevented and harsh magnetic noise is suppressed.
