Patent ID: 8097997

Claim:
A driving device with a rotating electric machine, comprising: a case having an opening; a rotating electric machine stored in said opening of said case and having a stator; a gear wheel stored in said case and connected to said rotating electric machine; a cover sealing said opening; and a fastener fixing said rotating electric machine to said case, wherein said stator has first and second thrust end faces defining an axial length thereof, said first thrust end face is pressed against an inner surface of said case, said first thrust end face is located proximal to a shaft connected to an engine and said second thrust end face is located distal to said shaft, said stator has a stator core and a part of an outer periphery of said stator core is in contact with the inner surface of said case, and said second thrust end face is spaced from said inner surface of said case, the entire second thrust end face is not in direct contact with the case, and the driving device further comprising: a pressing member bringing the outer periphery surface of said stator core into contact with the inner surface of said case by pressing said stator core in a radial direction; and a hardened member extending along an inner length of the pressing member, wherein said fastener extends through the pressing member, the hardened member, a hole formed in said stator core and a portion of said inner surface of said case, said fastener fixing said pressing member to said stator core.
