We construct the action-angle variables for the spherical part of conformal mechanics describing the motion of a particle near extreme Kerr throat. We indicate the existence of the critical point vertical bar p(phi)vertical bar = mcR(Sch) (with m being the mass of the particle, c denoting the speed of light, R-Sch =2 gamma M/c(2) being the Schwarzschild radius of a black hole with mass M, and gamma denoting the gravitational constant), where these variables are expressed in elementary functions. Out from this point the action-angle variables are defined by the elliptic integrals. The proposed formulation allows one to easily reconstruct the whole dynamics of the particle both in initial coordinates, as well as in the so-called conformal basis, where the Hamiltonian takes the form of conventional non-relativistic conformal mechanics. The related issues, such as semiclassical quantization and supersymmetrization are also discussed.
