PROBLEM TO BE SOLVED: To reduce the weight of a vibration control device while imparting anisotropy to spring characteristics in an axial perpendicular direction. SOLUTION: A resin outer cylinder 14 surrounding a shaft member 12 is molded to have a weld part 28 in at least one place in the circumferential direction C by resin injected from a resin injection port 26 set to at least one place in the circumferential direction C. A circumferential position where the weld part 28 is formed is provided with a convex part 30 for raising a spring constant in the axial perpendicular direction Yb by projecting inward Yi of the axial perpendicular direction to narrow an interval from the shaft member 12. By this, the circumferential position where the weld part 28 is formed is formed to be thick. COPYRIGHT: (C)2011,JPO&INPIT |
