Abstract

PURPOSE: To simplify conservation and inspection and make the device compact by supporting an outer rotor by means of an elastic body provided on an impeller.
CONSTITUTION: Ring-shaped projection 11 and conical projection 13 respectively of impeller 3 and outer rotor 2 are engaged with tapers 12 and 14, and thereby play in the radial direction is eliminated. At the same time, inward projection 8 of elastic body 5 comes into contact with conical projection 13 of outer rotor 2 and further pushes it to the motor side by resisting its elastic force. As a result, when outward projection 7 passes hole 10 of outer rotor 2, it is pushed inward, and after passing, it places itself outward by its elastic force and maintains the motion of impeller 3 in the axial direction. When impeller 3 is removed, push elastic body 5 inward from notch 9 of boss 4 and disengage the outward project from hole 10. The elastic force of inward projection 8 operates in the direction to separate impeller 3 from the outer rotor. Thus, it is possible to simplify conservation and inspection and to make the device compact.
