CYLINDRICAL VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To reinforce a rebound-side stopper function at a reverse start and improve the moldability of a stopper part in a cylindrical vibration control device applied as a rear engine mount. SOLUTION: A stopper part 4 comprising an insert member 41 whose outer surface is a substantially arc surface along the inner circumference of a substantially circular outer cylinder member 1 and a rubber layer 42 covering the surface is disposed in opposition to the crest of a substantially V-shaped rubber vibration isolator body 3 disposed between the outer cylinder member 1 and an inner cylinder member 2. End faces 44 of the insert member 41 continuous with the substantially arc outer surface are inclined inward of lines B connecting both end edges of the arc and the center of the outer cylinder member 1, so that a rubber material injected from both ends of the insert member 41 in molding flows smoothly along the end faces 44 and refrains from deformation, which leads to improved moldability.
