A weak temperature dependence was observed in the Knight shift at the O site ($^{17}K$). The spin part of $^{17}K$ ($^{17}K_{\\rm spin}$) is estimated from the plot of $^{17}K$ against bulk susceptibility $\\chi$. The $^{17}K_{\\rm spin}$ decreases in the SC state, indicative of the decrease in the in-plane component of the spin susceptibility.
