  The Kondo effect in a $p_x + {\rm i} p_y$-wave superconductor is studied by
applying the Wilson's numerical renormalization group method. In this type of
superconductor with a full energy gap like a s-wave one, the ground state is
always a spin doublet, while a local spin is shrunk by the Kondo effect. The
calculated magnetic susceptibility indicates that the spin of the ground state
is generated by the orbital effect of the $p_x + {\rm i} p_y$-wave Cooper
pairs. The effect of spin polarization of the triplet superconductor is also
discussed.
