A snap-fit fastening system for use in attaching a member to an electric motor utilizes stator through-bolts with specially formed heads and the member includes a plurality of slots formed in a pattern similar to the pattern in which the through-bolt holes of the stator laminates are arranged, but with the slots extending radially relative to the central axis of the stator and being offset laterally relative to the associated holes. An annular flange integrally formed with each bolt intermediate its ends seats on the top laminate to confine deflection of the upper end of the bolt to movement in a generally radial direction. Bullet-shaped extensions integrally formed with the upper ends of the bolts telescoped into the slots so a lip formed in each extension snap-fits the member onto the bolts, the lips overlapping the edges of the slots to lock the member on the through-bolts. |
