ABSTRACT:
A stopper for a cylindrical elastic mount includes a concave portion which is formed at each of a plurality of locations on a circumference of a cylindrical portion of a stopper fitting, the concave portion being concaved in a radially inward direction to partially enlarge a width of an outward flange so as to provide a large width portion on an enlarged width portion of the outward flange of a first rubber portion. The stopper further includes a plurality of second rubber portions each of which is fixedly disposed only between adjacent concave portions in a circumferential direction of a bottom portion and protruding higher than the first rubber portion. The first and each of the plurality of the second rubber portions are separated by a groove-shaped gap that is provided so as to continuously extend around each of the plurality of second rubber portions.
