Patent ID: 8893625

Claim:
A rubber stopper for limiting relative displacement of a plurality of members, comprising: a holding fitting fastened by means of bolting to one of the plurality of members; and a rubber section that is held by the holding fitting and abuts against another of the plurality of members, wherein the holding fitting has a partition wall that divides between a peripheral edge of a bolt hole through which a fastening bolt is inserted and a holding section that holds the rubber section, in the rubber section, a rubber side abutment surface that abuts against said another member is provided to protrude from a top of the partition wall, and a bored section is formed near the partition wall; wherein said bored section of said rubber section that is formed near said partition wall is a recess in said rubber side abutment surface adjacent said partition wall configured such that upon compressing said rubber section by pressure of said another member against said rubber side abutment surface, said rubber section deforms into said recess such as to reduce local stress of the rubber section restrained by said partition wall.
