VIBRATION CONTROL BUSH
DRIVE
April 30, 2020
To provide a vibration control bush that ensures improved durability of a rubber elastic body. An inner pipe film portion of the vibration control has an inclined surface whose inclination angle θ with respect to an axis O direction is set to one degree or more and less than three degrees, and the inner pipe film portion has an end portion in the axis O direction whose thickness dimension is set to a quarter or less of a dimension in an axis O perpendicular direction from an outer peripheral surface of an inner pipe to an apex of the protruding portion. This ensures reducing a rubber elastic body to deform so as to bend (close contact) between the inner pipe film portion and the outer pipe film portion when a load in a wrenching direction is input. Accordingly, a durability of the rubber elastic body can be improved.
