Claim Text:
1. A driver device comprising: a motor driven by an electric power supplied to a winding wire within the motor; a rear frame end serving as a first heat dissipater disposed on an axial end of the motor; a second heat dissipater having a heat generator fastened thereon; a connector case disposed on an outside of the second heat dissipater and having a connector connecting the second heat dissipater to an external device; and a plate member attached to a plate base that is formed on the connector case, the plate member contacting (a) the first heat dissipater with a motor-facing contact face and (b) the second heat dissipater with a motor-facing-away contact face, wherein heat conductivity of the plate member is equal to or greater than heat conductivity of the first heat dissipater and the second heat dissipater combined.
