Resumen:
In this paper we study a maximal operator Mf related with the best $ L^\phi $approximation by constants for a function $f \in L\phi'$. We get a necessary and su±cient condition which assure strong inequalities  for this maximal function.approximation by constants for a function $f \in L\phi'$.
