PURPOSE: A bearing case assembly is provided to prevent oil from becoming leaked to between a case and a shaft since a ring shape of a closed loop is formed along the circumference of the shaft with a packing. CONSTITUTION: A bearing case assembly comprises a bearing case, a cover, a packing(130), an air path(140), and a guide path(150). The bearing case connects two shafts. The cover is coupled to the case to cover a part making contact with the case. The packing is formed in the cover to protect the shaft. The air path is formed on the cover to make contact with the packing. The guide path is formed on the cover to be communicated with the air path and guides air to the air path. The packing forms a ring shape of a closed loop along the circumference of the shaft. The air path forms a ring shape of a closed loop corresponding to the packing.
