An in-wheel motor system for mounting a direct drive motor to a steering wheel comprises a first knucklewhich is connected to the non-rotary side of a geared motorby a connection member Ihaving elastic bodies and direct-moving guides for limiting movement to a vertical direction and locked in a steering direction by upper and lower suspension armsandand a second knucklewhich is connected to a steering rodand fitted with a brake unitand a wheelthrough a hub. This second knuckleis connected to the above first knucklein such a manner that it can turn on a king pin axis J in the steering direction and to the output shaft of the above geared motorby a connection shafthaving constant velocity jointsandat both ends, thereby reducing an increase in steering torque.
