[0005] In this embodiment, a bearing beam 10 is attached to the outside of the case 1 with cover bolts 12 and 12 covering the drive pulley 3 and the driven pulley 7.
A bearing 6 for supporting the tip of the drive shaft 2 can be fixed inside the bearing beam 10, and a bearing 8 for supporting the tip of the driven pulley 7 can be fixed. In this state, as shown in FIG. 2, the tip of the drive shaft 2 is supported by a bearing 6 fixed inside a bearing beam 10. A packing 14 made of an elastic material such as rubber is provided on the outer periphery of the bearing beam 10, and a cover 13 is attached to the outside of the bearing 14 in a cover-like shape.

The bearing beam 10 is provided with several stud bolts 11, 11, 11 projecting outward, and each of the stud bolts 11, 11, 11 is made of an elastic material such as rubber. The collar 13 is fitted to the outside, the cover 13 is attached to the stud bolt 11 via the collar 15, and the nut 16 is fastened to each stud bolt 11 from outside to attach the cover 13. Therefore, the cover 13 is composed of the packing 14 and the collar 1.
5 is attached in a cover-like manner in a state where the vibration can be absorbed by the elastic force of No. 5. In such a structure, the vibration transmitted from the drive shaft 2 and the like is transmitted to the bearing beam 10, but the vibration is absorbed by the packing 14 and the collar 15 and is not transmitted to the cover 13, and the cover 13 causes film vibration.

As shown in a half sectional view of FIG. 3, the packing 14 may be attached to the case 1 so as to be in contact therewith.
The vibration is not transmitted to the cover 13 by the collar 15 and
Noise is reduced. Incidentally, with such a structure, the cover 13 can be made of a steel plate or a damping steel plate having a higher sound insulation effect, and the sound insulation effect can be further enhanced.
