<p>In order to practise an apparatus for driving an alternator of an engine which is capable of reducing a load on a transmission belt by a one-way clutch, a one-way clutch (27) is provided between an alternator shaft (11) and a rotor (19) in an alternator (1), which one-way clutch (27) is adapted to transmit a rotational force of the alternator shaft (11), which is transmitted from a crankshaft thereto via a transmission belt (3), to the rotor (19) when an angular speed of the crankshaft increases during the minute variation thereof, and stop the transmission of the rotational force between the rotor (19) and alternator shaft (11) so that the rotational inertial torque of the rotor (19) is not circulated to the crankshaft via the transmission belt (3) when the angular speed of the crankshaft decreases during the minute variation thereof. This enables the extension of the alternator shaft (11) to be rendered unnecessary even when the width of a pulley (la) connected unitarily to the alternator shaft (11) and having the transmission belt (3) passed therearound is small, and a one-way clutch-carrying alternator driving apparatus to be practised easily.</p> |
