<p>A fluid pump (1, 1 a, 1 b, 1 c) includes a drive shaft (10, 10a, 10b, 10c) driven by power from an engine, a rotor (20) adapted to be provided at a housing (11, 11 a, 11 b, 11 c, 12) and rotating unitarily with the drive shaft (10, 10a, 10b, 10c), a driving wheel (30, 30c) which is provided separately from the drive shaft (10, 10a, 10b, 10c) and to which the power from the engine is always transmitted when the engine is running, a driven wheel (40, 40a, 40b, 40c) transmitting the power from the engine to the drive shaft (10, 10a, 10b, 10c) upon being in contact with the driving wheel (30, 30c), and a displacement mechanism (50, 50c) causing the driving wheel (30, 30c) and the driven wheel (40, 40a, 40b, 40c) to be out of contact from each other by moving at least one of the driving wheel (30, 30c) and the driven wheel (40, 40a, 40b, 40c).</p> |
