Abstract
A cap of synthetic resin material for separating the wet and dry spaces of a motor/pump assembly and receiving the rotor of the motor has, at a bottom of the cap remote from the pump, a seat formed by axially-extending centering elements and detent arms which snap onto one of the bearings of the motor shaft and form-fittingly that retains that bearing in the axial and radial directions and prevents rotation thereof.
