Disclosed herein is a strut mount interposed between a vehicle body and a piston rod of a shock absorber of a suspension. The strut mount includes an interior member passed through by and fixed to the piston rod; an exterior member including a cylindrical part surrounding the interior member, and a bottom formed in a ring shape by extending radially inward from a lower end of the cylindrical part, an elastic member formed in a ring shape between the interior member and the exterior member, and sandwiched between a part of the vehicle body or an upper member and the bottom of the exterior member; and a positioner radially positioning the elastic member. The elastic member is not in contact with the cylindrical part of the exterior member over its entire axial length and over its entire circumference.
