For integer n\geqslant 1 and real number z\geqslant 1, define M(n,z):=∑d|n, d\leqslant zμ(d) where μ denotes the Möbius function. Put \cal L(y):=exp\(log y)3/5/(log2y)1/5\ (y\geqslant 3). We show that, for a suitable, explicit, constant L>0 and some absolute c>0, we have S(x,z)= Lx+O(x/\cal L(3ξ)c) uniformly for x\geqslant 1, ξ\leqslant z\leqslant x/ξ.
