CYLINDRICAL VIBRATION CONTROL DEVICE WITH A PLURALITY OF KINDS OF BRACKETS AND ITS MANUFACTURING METHOD

Japanese Patent JP2023039593

A

To provide a cylindrical vibration control device with a plurality of kinds of new brackets and its manufacturing method, capable of efficiently manufacturing each cylindrical vibration control device by achieving positioning of a center shaft of each rubber mount to each mounting hole and positioning in a circumferential direction, while adopting various brackets according to difference in vehicle types and mounting positions in manufacturing each cylindrical vibration control device.SOLUTION: In cylindrical vibration control devices 10, 90 with a plurality of kinds of brackets, brackets 12, 92 and a rubber mount main body 16 have non-rotationally symmetrical structures around a shaft, and in each of the cylindrical vibration control devices 10, 90 with the plurality of kinds of brackets, uneven positioning portions 20, 96 around the shaft to a jig 100 for press-fitting assembly disposed on the brackets 12, 92 and an engagement positioning portion 132 around the shaft to respect to the jig 100 for press-fitting assembly disposed on the rubber mount main body 16 are configured to have a relatively same positional relationship around the shaft.SELECTED DRAWING: Figure 2
