Title:
VIBRATION ISOLATION DEVICE
Document Type and Number:
Japanese Patent JP2018100727
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration isolation device capable of improving the durability of a vibration isolation base while differentiating spring constants in two directions perpendicular to the axis line.SOLUTION: A joint part to the outer periphery of which the vibration isolation base is joined includes a chamfered portion formed by cutting the corner where a flange part and the joint part are communicated, a base portion linked to the chamfered portion in its axial direction, and a front end portion linked to the base portion in its axial direction. Compared to the area of the first projection surface of at least the front end portion of the joint part projected in a first direction perpendicular to the axis line, the area of the second projection surface of it projected to a second direction perpendicular to the axis line and the first direction is set larger.SELECTED DRAWING: Figure 2
