  We present results of phase shift for I=2 $S$-wave $\pi\pi$ system with the
Wilson fermions in the quenched approximation. The finite size method proposed
by L\"uscher is employed, and calculations are carried out at $\beta=5.9$
($a^{-1}=1.934(16)$ GeV from $m_\rho$) on $24^3 \times 60$, $32^3 \times 60$,
and $48^3 \times 60$ lattices.
