Abstract: A bush includes an inner cylinder, an outer cylinder, a cylindrical elastic member interposed between the inner cylinder and the outer cylinder, a flange formed on one edge of the outer cylinder, and an elastic brim extending from the cylindrical elastic member. The flange engages with one end face of the cylindrical member, and the elastic brim covers an end face of the flange. The flange includes a thick portion that protrudes toward the elastic brim side.

Abstract: There is provided a suspension arm mounting structure in which a mounting end portion 2 of a suspension arm 1 is fastened relative to a vehicle body 4 with a bolt 11 and a nut 12 and in which the wheel alignment is adapted to be adjusted by displacing the bolt in a direction orthogonal to an axis thereof through rotation of a pair of plate cams 15, 19 disposed at ends of the bolt, characterized in that a cylindrical collar 13 is provided over a shank portion 11b of the bolt; in that one 15 of the pair of plate cams and an engagement portion 16 for engagement with a turning tool are provided at one end of the cylindrical collar in such a manner as to prohibit a relative rotation therebetween, and in that an engagement portion 17 is formed on the other end of the cylindrical collar so as to prohibit a relative rotation between the cylindrical collar and the other 19 of the pair of plate cams.
