We obtain a local regularity result for solutions to Kψ,θ -obstacle problem of A-harmonic equation divA(x, u(x), ∨ u(x))=0, where A: Ω×R×Rn → Rn is a Carath\'eodory function satisfying some coercivity and growth conditions with the natural exponent 1<p<n, the obstacle function ψ≥0$, and the boundary data θ ∈W1, p(Ω).
Key words: local regularity; A-harmonic equation; obstacle problem
