Abstract
To reliably prevent the occurrence of a pull out phenomenon in a magnetic driving pump of a vehicle internal combustion engine where permanent magnets, magnetized to have alternate N poles and S poles around an axis of a drive shaft and a driven shaft, are respectively fixed to the drive shaft and the driven shaft. The drive shaft is interlocked with a crankshaft and the driven shaft is coaxially mounted with the drive shaft. Furthermore, the permanent magnets are magnetized to have alternate N poles and S poles 90 degrees or 180 degrees in phase in a peripheral direction.
