Vehicle steering apparatus

摘要

An electric motor (4) provided in a vehicle steering apparatus (1) includes a stator (25) coaxially surrounding a steering shaft (5), an inner rotor (26) disposed on the inner periphery of the stator (25), and an cuter rotor (27) disposed on the outer periphery of the stator (25). The facing area between the stator (25) and the rotor can be increased by providing the inner rotor (26) and the outer rotor (27) in the electric motor. Consequently, the electric motor (4) can be miniaturized while a certain output thereof is maintained. The vehicle steering apparatus (1) can be miniaturized by miniaturizing the electric motor (4).
