Abstract
A wrapped bush having its ends joined at a joint. First and second joint portions are formed in the corresponding end portions of the bush that are to be joined at the joint, and they each have at least one pair consisting of a recess and a projection. The first and second joint portions are of the same configuration and of the same size but are formed at positions shifted along the corresponding end portions. Further, the first and second joint portions are arranged in such a manner that, when the end portions of the bush are joined, one joint portion formed in one end portion is supplementary with the other joint portion formed in the other end portion.
