<P>PROBLEM TO BE SOLVED: To prevent operation of an electric oil device from becoming unstable by a hydraulic fluid viscosity variation by the temperature. <P>SOLUTION: In this electric hydraulic device such as an electric hydraulic power steering device for a vehicle, an inverter 42 for controlling an electric motor 50 is integrally constituted adjacent to the electric motor 50 for driving a hydraulic pump 60. A hydraulic pipe 66 is arranged in close vicinity to the inverter 42, and heat generated from the inverter 42 and the electric motor 50 is transmitted to the hydraulic pipe 66, restraining a temperature change in a hydraulic fluid. <P>COPYRIGHT: (C)2011,JPO&INPIT |
