Abstract: A racing pigeon foot ring shell comprises a body and a movable member. A first terminal of the body is formed with at least one pivoting hole, and a second terminal opposite to the first terminal is formed with a first engaging portion. A pivoting terminal of the movable member is formed with at least one protruding pivot, and the at least one protruding pivot is detachably inserted into the at least one pivoting hole to be pivotally connected with the body. An engaging terminal opposite to the pivoting terminal is formed with a second engaging portion, and the second engaging portion is detachably engaged with the first engaging portion. A pivot structure of the present invention is formed on the movable member, so that the body and the movable member can form a pivoting connection without an additional metal pivot.
