Claims

[Scope of utility model registration request]

The drive shaft of an automobile water pump is rotatably driven by an electric motor, and a driven pulley, which is rotatably driven via a belt by the rotation of the engine crankshaft, is attached to the drive shaft via a one-way clutch. , a driving device for an automobile water pump, in which this one-way clutch is only capable of transmitting the rotation of the driven pulley to the drive shaft.
