    • A joint boot fitted to an outer case formed in a non-circular outer peripheral shape capable being axially positioned without impairing mountability on the outer case. The joint boot (10) comprises a boot body (18) having a large diameter side mounting part (12), a small diameter side mounting part (14), and a bellows part (16) and a bush (20) interposed between the outer case and the large diameter side mounting part. The outer peripheral surface of the bush is formed in a circular shape in cross section, and a plurality of projected parts (16) are circumferentially dispersedly formed on the inner peripheral part of the bush fixedly fitted onto the outer case. A projection (56) fitted to a groove (54) formed in the outer peripheral surface of the outer case and extending in the circumferential direction is formed on the inner peripheral surface of the bush at a position out of the externally fitted area (Q) thereof by the large diameter side mounting part in the axial direction of the bush.
