The present invention provides a bearing bracket supporting a drive shaft to allow axial rotation. The bearing bracket comprises a first bracket and a second bracket. The first bracket includes: a first head part, into which a drive shaft is inserted; and a first mounting part extended from one end of the first head part and having an end fixed to a fixed body. The second bracket includes: a second head part, into which the drive shaft is inserted; and a second mounting part extended from one end of the second head part and having an end fixed to the fixed body. The first head part and the second head part are coupled in such a manner to open each other to allow the drive shaft to pass through. According to the present invention having the above described structure, coupling of the fixed body is formed at two spots, thereby improving the dynamic stiffness and unique number of vibrations. In addition, as coupling force is increased, aluminum is used as material instead of conventional cast iron, thereby allowing lighter weight. |
