摘要： In a suspension bushing of a vertical type, a spring in the axial direction is increased and a spring in a twisting direction is decreased thereby reducing a stress strain. [Means for solving the object] A suspension bushing is comprised of an inner cylinder 22, an intermediate plate 26, an outer cylinder 24 and an elastic member 28 for elastically connecting these components. An axis C of the inner cylinder 22 is arranged vertically in an up and down direction (a Z direction). The inner cylinder 22 is provided with an expanded portion 30 in an axially central region. The expanded portion 30 is enclosed by a curved surface section 40 formed in an axially central region of the intermediate plate 26. An axially outward expanded end section 44 is provided on either side of the curved surface section 40 of the intermediate plate 26 via a most approaching portion 42. An inside annular recess 54 and an outside annular recess 56 are provided on an axially outward end of the elastic member 28. When the twist is inputted, the outer cylinder 24 and the intermediate plate 26 are changed relative to the inner cylinder 22. However, due to the provision of the expanded end section 44, a twist angle Θ is increased so that the intermediate plate 26 is hard to interfere with an end portion 34 of the inner cylinder 22 and a spring in a twisting direction is decreased. In addition, since a volume increasing portion 58 is provided in a concave of the most approaching portion 42, a spring in the axial direction is increased.
