Abstract
PURPOSE: To facilitate boring work in a housing by constituting the bearing part of a drive shaft with a pair of bearings having the same diameter to be fitted in the boss part of the housing.
CONSTITUTION: The bearing part 30 for a drive shaft 11 to which a rotor 3 is fixed is composed of a cylindrical boss 31 provided beside the housing 1 body solidly and a pair of bearings 32, 33 with the same diameterfitted in the hole 31a excavated in the boss 31. Accordingly, the hole 31a designed for inserting the drive shaft 11 can be made straight with a uniform inside diameter, so that it can be machined in a single approach together with a space 8 to accomodate the pump body 3. Thus, the boring work in the housing can be facilitated.
