PURPOSE: To avoid inherent noise and to provide satisfactory damping by forming a thick-walled part in an annular shape, providing a bulkhead starting from a projecting part and having a thickness increasing in the direction of the thick-walled part, and allowing one side of a rubber mount to abut to a support body of a receive base by the thick-walled part. CONSTITUTION: A thick-walled part 8 is formed into an annular shape and extends in parallel with a projecting part 4 across an interval in the radial direction from the projecting part 4. A bulkhead 3 starts from the projecting part 4 and has a thickness increasing in the direction of the thick-walled part 8. At least one side of a rubber mount can abut to a support body 9 of a receive base 1 by the thick-walled part 8. Consequently, it is possible to avoid inherent noise and provide satisfactory damping of vibration having a large amplitude. |
