Abstract
A power steering apparatus provided with an electromagnetic clutch disposed between an output shaft of a steering assisting motor and a transmission shaft connected to a steering mechanism, an intermediate transmission shaft supported between the output shaft and transmission shaft and supporting an armature part of the electromagnetic clutch, and a biasing member to bias the intermediate transmission shaft in the axial direction. The intermediate transmission shaft is pressed to the side of the output shaft by the biasing member and a fixed initial gap is formed between a friction plate fixed to the output shaft and another friction plate fixed to the armature part. In addition, this power steering apparatus is provided with a shielding member between a reduction unit and the electromagnetic clutch for shielding these two from each other. Lubricant scattering from the reduction unit is prevented from reaching the electromagnetic clutch owing to the presence of the shielding member.
