The present invention relates to an inner shaft bearing bracket structure. The present invention includes: an inner shaft disposed in a vehicular width direction between a differential gear or a decelerator connected to an engine or a motor generating vehicle rotation power and a drive shaft which transmits rotation power to a vehicle wheel; a bearing that surrounds an outer circumferential surface of the inner shaft and is rotatably coupled with the inner shaft; and a bearing bracket that connects a pipe which accommodates and supports the bearing therein to a boss formed to protrude forward in the engine or the motor. The bearing bracket is arranged on a side surface of the boss, and is bolt-coupled in the vehicular width direction of a vehicle body. A natural frequency and dynamic stiffness of the bearing bracket can be increased, thus vehicle noise and vibration problems can be addressed. Also, the weight of the vehicle and the labor can be reduced. |
