<p>A vibration isolator includes: an inner cylindrical metal member 10; a stopper member 13 which is fixed at its axial intermediate position and is projected into a vibration input direction; an outer cylindrical metal member 28 arranged outside the inner cylindrical metal member; a rubber elastic member 20 which elastically connects between the inner and outer cylindrical metal members; and a support metal member 30 which is forced into an axial hole of the inner cylindrical metal member and has one end projecting from the inner cylindrical metal member. An axial intermediate portion of the inner cylindrical metal member including a locating portion of the stopper member is a large-diameter portion 11 which is slightly bulged into a diametrical direction and has inner and outer diameters slightly larger than inner and outer diameters of other portions. The support metal member is forced and inserted into the axial hole of the inner cylindrical metal member, and thereby, the large-diameter portion receives no influence; therefore, no damage is given to the stopper member. Moreover, a small-diameter portion of the inner cylindrical metal member is elastically deformed by a force fit, and thereby, a drawing force of the support metal member can be secured. <IMAGE></p> |
