An equilibrator for a universal head which is simple in construction, light-weight, and small-sized. The equilibrator includes a cylindrical cam which has an axis extending in a substantially horizontal direction, and is mounted on a base so as to be rotatable about the axis, and having a cam surface formed on an end thereof, in addition to a compression spring which is arranged so as to be substantially coaxial with the cylindrical cam and resiliently engaged with the cam surface of the cylindrical cam. The cam surface has a configuration sufficient to allow the balance between the force transmitted to the cam surface due to the inclination of the universal head and the restoring force of the spring, to be kept at any inclination of the universal head.
