Zero-field muon-spin-relaxation measurements have been carried out for LaSrCuZnO (LSCO)with 
= 0-0.10 in the overdoped regime up to 
= 0.30, in order to investigate whether the dynamical stripe correlations are pinned and stabilized even for the overdoped LSCO or not. It has been found that the Zn-induced slowing down of the Cu-spin fluctuations is weakened with increasing but takes place in the overdoped regime and disappears at = 0.30. This suggests that the stripe-pinning model holds good in the whole superconducting regime of LSCO and that there is no quantum critical point at 
0.19.
