The issue of the invention is to provide an arrangement structure of an electric automobile vibration isolating device with which it is possible to suppress a sudden increase in a dynamic spring constant of the electric automobile vibration isolating device when a load equal to or greater than a prescribed range acts on the electric automobile vibration isolating device. A through hole penetratingin an axial direction through an inner cylinder member (10) is not formed in a vibration isolating base body (30) in a position overlapping the inner cylinder member (10) in the direction of gravity,in a state in which an electric automobile vibration isolating device (100) is attached to a vehicle body of an automobile, and a characteristic of a load in the direction of gravity with respect toan amount of deflection of the vibration isolating base body (30) within a range of the amount of deflection of up to 30% of the free length of the vibration isolating base body is linear, and it is therefore possible to suppress a sudden increase in the dynamic spring constant when a load within a prescribed range acts on the electric automobile vibration isolating device (100) in the direction of gravity.
技术问题:提供一种能够在规定范围以上的载荷作用于电动汽车用防振装置的情况下,抑制电动汽车用防振装置的动态弹簧常数急剧增高的电动汽车用防振装置的配设结构。解决手段:关于电动汽车用防振装置(100),在与安装于汽车的车身的状态下的内筒部件(10)在重力方向上重叠的位置的防振基体(30),未形成沿着内筒部件(10)的轴向贯通的贯通孔,在到防振基体的自由长度的30%为止的挠曲量的范围内,重力方向的载荷相对于防振基体(30)的挠曲量的特性具有线性,因此能够在规定范围内的载荷在重力方向上作用于电动汽车用防振装置(100)的情况下,抑制动态弹簧常数急剧增高。
