  We derive a variety of exact black hole solutions in a subclass of
Horndeski's scalar-tensor theory possessing shift symmetry, $\phi\to\phi+c$,
and reflection symmetry, $\phi\to-\phi$. The theory admits two arbitrary
functions of $X:=-(\partial\phi)^2/2$, and our solutions are constructed
without specifying the concrete form of the two functions, implying that black
hole solutions in specific scalar-tensor theories found in the literature can
be extended to a more general class of theories with shift symmetry. Our
solutions include a black hole in the presence of an effective cosmological
constant, the Nariai spacetime, the Lifshitz black hole, and other nontrivial
solutions, all of which exhibit nonconstant scalar-field profile.
