Abstract
A rotary electric machine includes a rotor, a stator, a circuit substrate, a tubular closed-top and closed-bottom motor case arranged to accommodate the rotor, and bearings. The motor case is axially divided into a first casing and a second casing. Each of a first and a second tap portion of the first and the second casings includes an inner circumferential surface and at least one groove arranged on the inner circumferential surface. A lead bush includes a through-hole arranged to guide a lead wire and at least three annular bulging portions arranged at a specified interval along an outer circumferential surface of the lead bush. A middle annular bulging portion of the three annular bulging portions is fitted to the groove of each of the first tap portion and the second tap portion so that the lead bush is gripped between the first tap portion and the second tap portion.
