Vibration isolating device

摘要

A torque rod includes a rod main body, a first bushing and a second bushing. The rod main body is made of resin and provided integral with a first ring section and a second ring section on each end of an arm section. A first rib extends from the arm section to a front lateral surface of the second ring section. In a plan view, a second rib is provided to overlap with the first rib. The first rib projects forwardly of and in the left and right directions of the second rib. This projecting portion forms an enlarged diameter portion. Due to this enlarged diameter portion, an area of the first rib is made larger than an area of the second rib thereby to increase a rigidity of a forward side of the second ring.

主权项

1. A vibration isolating device comprising:
a main body including an arm section, a first ring section, and a second ring section, said first and second ring sections being each located on a respective end in a longitudinal direction of the arm section; a first bushing being provided in the first ring section; a second bushing being provided in the second ring section; and a plurality of horizontal ribs that extend in a plane orthogonal to a center axis of the second bushing, being formed on an outer periphery of at least the second ring section of the ring sections in a direction of the center axis of the second bushing; wherein the second ring section has a front side portion, which is connected to the arm section on a forward side with respect to the center axis of the second busing, and a rear side portion located on an opposite side; and wherein, in a plan view, the horizontal ribs are placed in an upwardly and downwardly overlapping relationship with each other and include a first rib and a second rib, which are different in area, wherein the first rib of a larger area has an enlarged diameter portion extending outwardly of the second rib of a smaller area and connecting the arm section and the second ring section, and the second rib is provided to extend from the front side portion to the rear side portion; and wherein the first rib extends from the arm section to only an outer periphery of the front side portion.
