Claims

[Scope of utility model registration request]

In a joint cover made of rubber or resin, which is attached to surround a joint and includes a bellows part that expands and contracts in accordance with the rotation of the joint, the bellows part is formed by changing the width of the bellows, and A joint cover characterized in that, during rotation, the inner surface of the bellows portion is positioned outward from the rotational movement locus of the end of the joint portion constituting the joint.
