US 2002/0002099 A1 · Mounting arrangement of vehicle rotary electric machine

Abstract

A vehicle rotary electric machine to be mounted in an engine is comprised of a rotor having a shaft, a stator, a front housing, a rear housing and a pulley. The front housing has a first mounting stay disposed at a side of the front housing to be fixed to a cylinder block of an engine by a bolt and a second mounting stay disposed at the opposite side of the front housing with respect to the shaft to be fixed to a cylinder head of the engine by a bolt having the same outside diameter. The rear housing has a third mounting stay to be fixed to the cylinder head at the same side of the rear housing as the second mounting stay. The first mounting stay has an elliptical first bolt-hole extending perpendicularly to the stack direction. The a major axis of the elliptical hole extends in parallel to the stack direction.
