<p>PURPOSE:To stabilize the signal fetch by forming a signal fetch means for fetching the electrical signal from an electrical equipment to the outside of a control force transmission system with a slip ring held by a rotating member of the control force transmission system and wire contacts held by a holder of the fixed side. CONSTITUTION:An electric power steering device transmits the driving force of an electric motor 19 of an assist means 1b to a control force transmission system 1a through an auxiliary force transmission system 1c. It also comprises a slip ring mechanism 1e for fetching the electrical signal from a resistor 14 (electrical equipment) for detecting the control force to the outside of the control force transmission system 1a. In this case, the slip ring mechanism 1e consists of a disc type insulating plate 31 fixed to the back face of a driving force relaying member 4 and a holder 32 fixed to an axis-to-axis distance holding plate 16. Multiple wire contacts 33 are made to contact to multiple wave- patterned slip ring 31a provided in the back face of the insulating plate 31, and the slip rings 31a are connected to the resistor 14 through lead wires or the like.</p> |
